Suzhou Delong Composite Materials Co., Ltd

What Suzhou Delong Composite Materials Co., Ltd does

Suzhou Delong Composite Materials Co., Ltd (苏州德龙复合材料有限公司) is a privately-held Chinese high-tech enterprise founded in 2009, specializing in Expanded Polypropylene (EPP) foam materials and precision die-cut components. The company is headquartered in Suzhou's Wuzhong Economic Development Zone with manufacturing operations in Huzhou (Zhejiang, 20,000 sqm, 150 staff) and Beijing (Fangshan, 10,000 sqm), and maintains international distribution via its Japan subsidiary Derlone (株式会社Derlone) and a Taipei Technical Service Center. Its core technology is EPP molding — a closed-cell polypropylene foam with density 17-100 kg/m³, temperature resistance from -40°C to 110°C, 100% recyclability, and energy-absorbing cushioning properties — which it converts into molded parts, sheets, and die-cut components for automotive, industrial packaging, and consumer applications.

The company serves three primary segments: (1) Automotive — supplying EPP bumper cores, side-impact protection, seat cushions, headrests, sun visors, tool boxes, and turnover/logistics containers to OEMs including Tesla, Benz, BAIC, and Chinese brands; (2) Industrial Packaging — protective EPP solutions for IGBT modules, LCD displays, communication equipment, medical devices, and silicon wafers; and (3) Cold-Chain Logistics — insulated EPP boxes for fresh produce, seafood, dairy, and food delivery. Adjacent product lines include EPP battery packaging for electric two-wheelers, EPP HVAC/fresh-air components, EPP water-cooling plate insulation pads, and precision die-cutting for EPP/EVA/EPDM materials. The company holds IATF 16949 automotive certification, ISO 9001, BSCI social compliance, Bureau Veritas, and National Safety Standardization certifications.

The business model is direct B2B manufacturing and OEM sales — quote-based pricing with MOQ around 1,000 pieces and stated production capacity of 10,000 pieces per week. Revenue is generated through custom EPP product manufacturing, custom mold development (15-20 day lead time after sampling), and integrated packaging solutions including panel boxes (围板箱) and wooden boxes. Disclosed annual sales revenue is 140 million RMB (~$19.5M USD). The company employs 200+ people including 50+ research personnel, runs deep industry-university-research (产学研) collaboration with multiple Chinese universities and research institutes, and distributes via its own domestic sales team, Alibaba international platform, and Japan distribution subsidiary.
