PVC Foam Board — Structural Composite Core Materials

Jiangsu Changhai Composite Materials Holding Co., Ltd. is a Changzhou supplier of glass-fiber reinforcement and thermoplastic composite materials. Its current official catalog and the 2026 China Composites Expo directory support roving, chopped strands, chopped strand mat, surface and continuous mat, woven roving, biaxial and stitched combinations, mesh, LFT reinforcement, CFRT tape and glass-reinforced thermoplastic panels. GetFRP assigns measured-demand phrases such as chopped strand mat, fiberglass cloth, fiberglass mat, fiberglass chopped strand mat and fiberglass panels only to these published products. The thermoplastic honeycomb offer is described as a core with continuous-glass-fiber-reinforced CFRT skins, not as a solid fiberglass panel or a claim that every honeycomb grade contains glass. Product-specific roving end uses do not mean Changhai manufactures the customer's finished pipe, SMC part or pultruded profile. The complete current logo was downloaded on 2026-08-26 from the exact CDN asset referenced by the official header, trimmed only to remove transparent canvas, and stored locally by GetFRP. Capacity, market-position and certification statements remain company claims pending certificate- and plant-level verification.

Ningbo Motong Composite Materials Co., Ltd. presents an integrated product, process, mold, equipment and line-development offer for series production of continuous-fiber composites. Its current official website describes non-preforming integrated prepreg compression molding (PPCM), hybrid CFRP or GFRP molding with metal, sandwich molding with paper fiber, foam, honeycomb or aramid, and a complete Type IV hydrogen-cylinder forming-process package covering liner, boss connection, high-speed low-carbon winding and rapid curing. SMC, HP-RTM and autoclave are listed as technology reserves. China Composites Expo independently lists the Ningbo company in its N directory. GetFRP treats these as engineering, process and line solutions. CFRP, GFRP, prepreg, metals and core materials are process inputs, while the Type IV vessel is a process-package target; none is presented here as Motong's standard raw-material or finished-cylinder catalog.

Diab Technology (Changshu) Co., Ltd. is the Jiangsu, China entity currently identified in the footer and contact information throughout Diab's Chinese website. The official portfolio covers Divinycell PVC, PET, PES and PEI foam cores, ProBalsa balsa, finishing, pre-cut kits and composite consulting. China Composites Expo lists the matching entity as DIAB TECHNOLOGY (CHANGSHU) CO., LTD. under foam core, balsa and sandwich panels. Diab's long group history, worldwide sites and application references do not automatically establish the Changshu entity's incorporation date, capacity or individual delivery record. This profile therefore leaves the establishment year empty and does not transfer every group approval to the Changshu company. Product and performance information still requires grade-, thickness-, finish- and manufacturing-site-specific verification.

Founded in 2011, Baoding Visight Advanced Material Technology Co., Ltd. presents itself on its official site as a developer, manufacturer and seller of high-strength lightweight structural core materials. The current portfolio covers Vicell V-series PVC foam, T-series PET foam, P-series PMI foam and B-series balsa core, with stated applications in wind energy, aerospace, marine, rail, new-energy vehicles, medical equipment, sporting goods and radomes. The site identifies operating or production entities in Baoding, Weihai, Lianyungang and Wangdu, plus a Gansu contact. China Composites Expo lists the same entity under foam core, balsa, sandwich panels and composite parts. Capacity, market-position, performance and application statements are company- or organizer-published and have not been independently audited by GetFRP.

Changzhou Tiansheng Composite Co., Ltd. is a structural-core exhibitor from Changzhou, Jiangsu listed by China Composites Expo under the English name CHANGZHOU TIANSHENG COMPOSITE CO., LTD. The current official website of Changzhou Tiansheng New Materials Group identifies Tiansheng Composite in its group structure and says a wholly owned subsidiary produces and processes structural foam. This is a parent-operated website, not a separate subsidiary domain. The official product pages list Strucell PVC structural foam, surface processing and pre-cut kits within the structural-foam range, while the expo classifies the exhibitor under foam cores, honeycomb cores and sandwich panels. The history page uses a shortened early subsidiary name, so the public official record reviewed here does not establish the current legal entity's incorporation year without ambiguity; no establishment year is assigned. The expo description also applies the parent's 2011 stock-market listing to the subsidiary profile, which must not be read as evidence that the subsidiary itself is listed. Corporate relationship, product, performance, market-position, project and certification statements are group- or organizer-published and have not been independently verified by GetFRP.

Yangzhou MAXTONE Composite Co., Ltd. (MTC) states that it has manufactured fiberglass composite panels and FRP sheets since 1996 and is a wholly owned subsidiary of Shanghai-listed Zhejiang Wazam New Materials Co., Ltd. (603186). Its published range focuses on FRP sandwich panels and flat sheets, PP honeycomb materials, and body panels or CKD kits for refrigerated, insulated and dry-freight vehicles, RVs and caravans.

Chengzi Tainuo (Shandong) New Material Technology Co., Ltd. is based in Feicheng, Tai'an, Shandong. Its current Chinese and English official sites publish the full legal identity under MIIT filing Lu ICP 2022005349. A 2024 issuer disclosure by Feicheng City Asset Management Group lists Chengzi Tainuo as a first-tier subsidiary with a 60% holding and classifies its business as chemical-fiber manufacturing. The official site focuses on continuous-fiber reinforced thermoplastic composites (CFRT), including UD prepreg tapes, thermoplastic laminates, PET-foam and PP-honeycomb sandwich panels, and composite sheets for vehicle bodies, containers, construction and pipeline reinforcement. China Composites Expo lists the same mainland-China entity under glass-fiber cloth/tape/mat, sandwich panel and finished-composite categories, while its exhibitor list publishes booth 7L15. Capacity, patent-count and domestic-first statements are company claims and have not been independently site-audited by GetFRP.

Dalian Yatai Science and Technology New Material Incorporated Co., Ltd. (Yatai Technology / Yatai Flame Retardant; NEEQ 832241) is a mainland-China magnesium flame-retardant and environmental-material supplier in Dalian, Liaoning. Its current Chinese and English sites present the incorporated identity, securities code, 2003 establishment and Dalian contacts, with content through 2025–2026. The site lists magnesium hydroxide and low-smoke halogen-free materials for cable, rubber, insulation-laminate/FR-4 and aluminum-panel uses, plus activated powder, core compounds, masterbatch, magnesium composite core rolls, mineral powders and desulfurization slurry. It also claims four mines, R&D and import/export. China Composites Expo lists a simplified DALIAN YATAI SCIENCE AND TECHNOLOGY NEW MATERIAL CO., LTD. identity and magnesium flame-retardant scope. The former limited-company wording, current incorporated name, English variants, Yatai brands, 832241 code, yataifr.com and historical dlyatai.cn have been deduplicated as one company. Unrelated Yatai companies are excluded.

Sinauva Composites Co., Ltd. presents itself as a Beijing-based developer, manufacturer and exporter of fiberglass-composite panels, structural foam cores, reinforcement materials and finished FRP products.

The company also states that it works with associated factories to broaden the range of related fiberglass products available to buyers.

Changzhou Utek Composite Co., Ltd. is based in Changzhou, Jiangsu. Its official website says the company was established in 2012, initially focusing on fiberglass, resins, SMC and BMC, and now positions the business as an overall composite-material solution provider. Its published catalog spans reinforcements, resins and chemicals, process consumables, core materials and axial fans. The company's China Composites Expo exhibitor listing says it produces powder- and emulsion-bonded chopped-strand mat, stitched mat, combination mat, warp-knitted fabric, core mat and fiberglass cloth, while also supplying alkali-resistant glass fiber, SMC/BMC, gratings and composite geosynthetics. These establishment, production and product-scope statements are company- or expo-published and have not been independently verified by GetFRP.
