PUBLIC COMPANY PROFILE

Hangzhou JLS Flame Retardants Chemical Co., Ltd.

Public profile · Not claimed
Hangzhou JLS Flame Retardants Chemical Co., Ltd. · Hangzhou, Zhejiang, China

Hangzhou JLS Flame Retardants Chemical is presented as a source-reviewed supplier profile centered on JLS-PNA220 intumescent flame retardants for PE, with company-published capability separated from buyer-side verification requirements.

Hangzhou JLS Flame Retardants Chemical Co., Ltd. is a Hangzhou supplier of halogen-free flame retardants, concentrates and wire or cable compounds. Its current catalog explicitly lists PNA, MB, PMP, MC, APP and FR families for PP, PE, glass-fiber PP, glass-fiber PA, CFRT, thermosets, TPE or TPU, PVC, ABS, coatings, textiles, sealants and adhesives. The 2026 China Composites Expo H directory lists the matching entity. Product fields contain only current grades and uses that can be traced to official pages. Although several grades are formulated for glass-fiber reinforced plastics and continuous-fiber thermoplastic composites, JLS is not presented as a fiberglass or carbon-fiber producer and substrate names do not trigger unrelated reinforcing-material traffic phrases. Buyers should qualify a grade against their own polymer, reinforcement, color, thickness, process and regulatory target rather than transferring a website example directly into production.

Company overview

This procurement profile is built for formulators, processors and procurement teams comparing chemistry, processing window, cured performance and regulatory documentation. It organizes Hangzhou JLS Flame Retardants Chemical Co., Ltd.'s published products, processes, certificate references and official sources around the primary topic “Hangzhou JLS Flame Retardants Chemical JLS-PNA220 intumescent flame retardants for PE.” The objective is to help a buyer decide whether to open a controlled RFQ, not to turn a broad company catalog into an unsupported approval.

Hangzhou JLS Flame Retardants Chemical Co., Ltd. currently lists 12 product or service groups and 10 manufacturing or support capabilities in this reviewed record. The public scope indicates what to investigate, while the buyer remains responsible for drawings, design calculations, standards, current certificates, sample approval and order-specific commercial confirmation. Claims below are attributed to the attached source set unless GetFRP explicitly labels them as qualification guidance.

Products & services summary

A flame-retardant package affects fire performance, mechanics, rheology, appearance, blooming, weathering and processing stability at the same time, so the RFQ must start with the exact polymer, reinforcement and process. Provide the PP, PE, PA, TPE, TPU, PVC, ABS or thermoset grade, glass or continuous-fiber type and content, target fire result, specimen thickness, color, molding route, temperature and shear history. State whether halogen-free, antimony-free, low-smoke, low-toxicity, low-VOC, hydrolysis, damp-heat, UV or electrical performance is required. For powder, lock chemical basis, active content, particle-size distribution, moisture, bulk density, whiteness, dispersion, thermal stability, impurities and package. For concentrate, lock carrier, flame-retardant loading, melt flow, pellet geometry, let-down ratio, matrix compatibility, drying, storage and lot variation. A finished cable compound also requires hardness, tensile, elongation, tear, abrasion, low temperature, heat aging, oil, water and chemical resistance, extrusion surface and line speed. CFRT, LFT-G, LFT-D, GFPP and GFPA programs should evaluate retained fiber length, wet-out, interface, flow, warpage, impact, blooming, mold deposit and recycled-content tolerance. Official pages mention examples or compatibility with UL94, BS476, ASTM E84, REACH and RoHS, but require the exact grade, formulation, thickness, color, laboratory, report number and revision; a result for one formulation cannot be transferred to another resin or part. Request current TDS and SDS, lot CoA, regulatory declarations, controlled samples, formulation trials, change notification and retention samples, and agree moisture-protected packing, shelf life, transport classification and complaint traceability. No original certificate or test file aligning company, address, scope, number, grade and validity was obtained in this review, so certifications and supported standards remain empty.

SOURCE-REVIEWED PROCUREMENT PROFILE

How to evaluate Hangzhou JLS Flame Retardants Chemical Co., Ltd. for JLS-PNA220 intumescent flame retardants for PE

Evaluate Hangzhou JLS Flame Retardants Chemical Co., Ltd. as a potential composite resin supplier for JLS-PNA220 intumescent flame retardants for PE, PP and glass-fiber PP, verify the public evidence and prepare a comparable RFQ.

Published product scope, translated into buying checks

JLS-PNA220 intumescent flame retardants for PE, PP and glass-fiber PP

Hangzhou JLS Flame Retardants Chemical Co., Ltd. includes this product in its published supply scope. Treat that listing as a starting point: request the current datasheet or drawing, material and construction, available grades or dimensions, guaranteed properties, production site, quotation revision and evidence that represents the exact item offered.

JLS-PNA flame retardants for glass-fiber PA6, PA66 and thermosets

For JLS-PNA flame retardants for glass-fiber PA6, PA66 and thermosets, buyers should convert the catalog description into an acceptance specification. Confirm standard and custom options, raw-material system, critical tolerances, surface or finish, test basis, sample route, MOQ, lead time and packing. Any alternative proposed by Hangzhou JLS Flame Retardants Chemical Co., Ltd. should be identified explicitly rather than treated as automatically equivalent.

JLS-PNA380 flame retardant for glass-fiber reinforced PA

This product broadens the supplier's public portfolio, but GetFRP does not infer approval from a product name alone. Ask Hangzhou JLS Flame Retardants Chemical Co., Ltd. for the grade or model designation, manufacturing route, current technical file, production and test location, batch traceability and the limits that apply to published performance values.

Manufacturing and service capability review

Halogen-free intumescent flame-retardant formulation

Hangzhou JLS Flame Retardants Chemical Co., Ltd. publishes Halogen-free intumescent flame-retardant formulation as part of its capability scope. Buyers should ask which site and equipment perform the work, the practical size or material limits, the normal control records and whether the proposed order uses the same route. Subcontracted stages should be visible in the quality plan.

Flame-retardant powder manufacture with particle and moisture control

The relevance of Flame-retardant powder manufacture with particle and moisture control depends on the requested product and acceptance criteria. During qualification, request a process flow, critical control points, inspection or test method, operator or equipment qualification where applicable, nonconformance handling and a recent example that represents the offered production route.

PP, PE and PA carrier masterbatch pelletizing

For sourcing purposes, PP, PE and PA carrier masterbatch pelletizing is a capability signal rather than independent verification. Confirm capacity, tooling or fixture availability, setup and changeover assumptions, lot definition, sample approval and traceability. The quotation should identify any limitation that could affect geometry, performance, appearance or delivery.

Flame-retardant formulation for GFPP, GFPA and CFRT

Buyers evaluating Flame-retardant formulation for GFPP, GFPA and CFRT should connect the process claim to evidence: an equipment list, controlled procedure, representative report, production photograph or witnessed sample may each answer a different risk. Hangzhou JLS Flame Retardants Chemical Co., Ltd. should also explain how the result is checked before release and recorded for the shipment.

Application fit to evaluate

These are sourcing contexts suggested by the published product scope, not confirmed project references. Validate the exact application, design basis and evidence in the RFQ.

Composite reinforcement and laminate production

Hangzhou JLS Flame Retardants Chemical Co., Ltd.'s reinforcement range can be screened for laminating, pultrusion, winding, molding or conversion programs. Buyers should confirm grade, sizing, architecture, width, tex or areal weight, package, splice and moisture limits, then run a representative processing trial before approving the material for repeat production.

Composite molds, dies and production tooling

Hangzhou JLS Flame Retardants Chemical Co., Ltd.'s tooling scope can be considered for new or replacement production tools. Buyers should release controlled product and interface drawings, material and process assumptions, critical datums, tool material and treatment, heating or flow requirements, trial conditions, acceptance measurements, ownership, maintenance and protected transport.

Pultrusion, winding and closed-mold processing

Hangzhou JLS Flame Retardants Chemical Co., Ltd.: The resin portfolio may be relevant to continuous or closed-mold composite processing. Qualification should cover viscosity, mix ratio where applicable, gel or reaction profile, cure conditions, exotherm, reinforcement wet-out and the cured properties required by the actual line and section thickness.

Supplier qualification checks

State the process, reinforcement, part thickness, cure equipment and target production cycle.
Request current technical and safety data sheets, mix ratio, viscosity window, storage life and handling controls.
Define cured mechanical, thermal, fire, chemical or surface properties with test methods and conditioning.
Run a representative process trial and record resin temperature, mix accuracy, gel profile, cure and observed defects.
Confirm batch certificate fields, shelf-life policy, change notification and complaint sample retention.
Review dangerous-goods status, packaging, temperature exposure and destination regulatory documentation.

What to include in an RFQ

  1. 1Product definition: identify the requested JLS-PNA220 intumescent flame retardants for PE, PP and glass-fiber PP, drawing or grade revision, dimensions, material construction, quantity and expected annual demand.
  2. 2Performance: state the loads, environment, temperature, chemical, fire, electrical, appearance or service-life requirements that actually control selection.
  3. 3Process and source: ask whether Halogen-free intumescent flame-retardant formulation is performed by Hangzhou JLS Flame Retardants Chemical Co., Ltd. at the named production site and disclose subcontracted stages.
  4. 4Standards and evidence: name the required standard edition, test methods, report scope, laboratory or witness expectation and acceptance values.
  5. 5Quality plan: define the approved sample, incoming-material records, in-process controls, final inspection, sampling level, traceability and treatment of nonconforming product.
  6. 6Commercial boundary: request tooling or setup, MOQ, lead time, payment, warranty, Incoterm, export documents, packing dimensions and responsibility for transport damage as separate items.
  7. 7Change control: require written approval before changes to material, formulation, reinforcement, production site, tooling, critical process, specification or certificate status.

Evidence and review scope

Hangzhou JLS Flame Retardants Chemical Co., Ltd.'s source record currently includes Official JLS Website, JLS Product Directory, Thermoplastic Composite HFFR Masterbatch, Official JLS Contact. These links let a buyer distinguish company-published information from GetFRP's own qualification guidance and return to the original context when a claim changes.

No company-level certification is presently listed in the reviewed profile. That does not prove that no document exists, but it means the RFQ should ask for the quality-system certificate and every product-specific test or approval needed by the buyer rather than assuming a certification from market reputation.

GetFRP last recorded a public-source review date of 2026-08-25. Public websites and catalogs can change after review, so commercial decisions should use newly downloaded files and direct supplier confirmation. GetFRP's public or claimed status describes profile ownership and identity controls; it does not certify every product statement or predict order performance.
