Chengdu Yulong Chemical is presented as a source-reviewed supplier profile centered on Melamine cyanurate (MCA) halogen-free flame, with company-published capability separated from buyer-side verification requirements.
Chengdu Yulong Chemical Co., Ltd. is a chemical-materials company in Qingbaijiang, Chengdu, Sichuan. Its official site traces the operating history to a state-owned small nitrogen-fertilizer demonstration plant established in 1958, described as the first of its kind in Southwest China. The current product center lists MCA halogen-free flame retardants, melamine foam, polyurea, urea, organosilicon catalysts and water-treatment chemicals, while separately identifying low-viscosity PVB resin as made by a controlled company. China Composites Expo lists the same entity as CHENGDU YULONG CHEMICAL CO., LTD. and publishes historical descriptions of melamine, ammonia, urea, ammonium bicarbonate and compound-fertilizer operations; its current net-show entry supplies neither a product category nor booth number. Historical origin, capacity, performance and market-position statements are company- or organizer-published and have not been independently site-audited by GetFRP.

This procurement profile is built for formulators, compounders and procurement teams comparing additive chemistry, dispersion, process compatibility, finished-material performance and regulatory evidence. It organizes Chengdu Yulong Chemical Co., Ltd.'s published products, processes, certificate references and official sources around the primary topic “Chengdu Yulong Chemical Melamine cyanurate (MCA) halogen-free flame.” 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.
Chengdu Yulong Chemical Co., Ltd. currently lists 7 product or service groups and 6 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.
The principal composites-relevant product is melamine cyanurate (MCA) flame retardant. The official site says its base MCA is used in synthetic resins, rubber, lubricants and fire-protection coatings; modified MCA-1/MCA-2 target PA6/PA66 and MG-3 targets silicone, with company-stated formulations reaching UL 94 V-0. These statements come from a 2018 company product page and are not a current product certificate or a blanket guarantee for every finished compound. An RFQ should define MCA grade, CAS/chemistry, purity, particle-size distribution, moisture, whiteness, decomposition temperature, loading, polymer and glass-reinforcement system, target thickness and flame rating, and require current TDS, SDS, batch CoA, impurity/heavy-metal/ionic data and accredited test reports for the exact formulation and thickness. Melamine foam needs density, open-cell content, dimensions, acoustic absorption, thermal conductivity/stability, smoke-toxicity and fire-test methods. Polyurea needs A/B chemistry, mix ratio, solids/VOC, gel and tack-free time, tensile/elongation, adhesion, thickness, media resistance, substrate preparation and application equipment. Organosilicon catalyst orders need active chemistry, impurities, particle size, dosage and methylchlorosilane-process conditions. The official urea page cites GB/T 2440-2017, but buyers should confirm the current standard revision, agricultural or industrial grade, biuret, moisture, particle size and packing. A 2018 company-introduction page claims ISO 9001, ISO 14001 and cleaner-production audit status but exposes no current certificates, numbers, scopes, expiry dates or issuer status; no certification is recorded as verified here. The PVB page expressly names controlled company Chengdu Longcheng Advanced Materials Co., Ltd. as manufacturer, so quotation, contract, invoice, production site, CoA and quality responsibility must identify the actual legal entity. Before ordering any chemical, verify the current SDS, hazard and transport classification, Chinese hazard label, regulatory inventory status, HS code, packing and storage conditions. Export transactions also require current customs, export-control and sanctions review based on exact composition, use, destination and end user.
No company-level certification is listed on this profile.
Evaluate Chengdu Yulong Chemical Co., Ltd. as a potential composite additive and functional-filler supplier for Melamine cyanurate (MCA) halogen-free flame retardants, verify the public evidence and prepare a comparable RFQ.
Chengdu Yulong 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.
For Melamine and melamine foam, 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 Chengdu Yulong Chemical Co., Ltd. should be identified explicitly rather than treated as automatically equivalent.
This product broadens the supplier's public portfolio, but GetFRP does not infer approval from a product name alone. Ask Chengdu Yulong 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.
A useful RFQ for Catalysts for direct synthesis of methylchlorosilanes should describe the buyer's application without disclosing unnecessary proprietary detail, then state the measurable product requirements. Compare Chengdu Yulong Chemical Co., Ltd.'s response against the same dimensions, quantity, inspection, documentation, Incoterm and delivery assumptions used for every shortlisted supplier.
Chengdu Yulong Chemical Co., Ltd. publishes MCA nitrogen-based halogen-free flame-retardant production and modification 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.
The relevance of Melamine and open-cell melamine-foam production 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.
For sourcing purposes, Two-component polyurea formulation and application support 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.
Buyers evaluating Organosilicon-catalyst production 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. Chengdu Yulong Chemical Co., Ltd. should also explain how the result is checked before release and recorded for the shipment.
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.
Chengdu Yulong Chemical Co., Ltd.: A flame-retardant additive must be qualified in the actual polymer, reinforcement, filler package, thickness and process. Buyers should define the target fire, smoke, electrical, mechanical and aging requirements and request current evidence for the complete tested formulation rather than treating an additive description as finished-product compliance.
Chengdu Yulong Chemical Co., Ltd.: For masterbatch or compound supply, define carrier, active content, let-down ratio, pellet or powder form, dispersion, color, volatiles and batch tolerance. A representative processing trial should reproduce the intended equipment and record both process stability and finished-part properties.
Chengdu Yulong Chemical Co., Ltd.'s coating chemistry should be evaluated as a complete applied system. Define substrate preparation, primer, mix ratio, pot life, film build, cure conditions, adhesion, chemical and weather exposure, repair method and the current test evidence for the proposed formulation and thickness.
Chengdu Yulong Chemical Co., Ltd.'s source record currently includes Official Yulong Company Profile, Official Yulong Product Directory, Yulong MCA Flame-Retardant Page, Yulong Melamine-Foam Page. 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 2026-08-13. 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.
