Ningbo Forever Plastic Rubber Co.,Ltd

Ningbo Forever Plastic Rubber Co.,Ltd is based in China and currently lists eight active products across rubber items, gaskets, industrial sheets and specialised paper. The catalogue includes graphite gasket sheet, reinforced graphite sheet, gasket paper material, spiral wound gasket, reinforced graphite gasket, general rubber sheet, silicon rubber sheet and neoprene rubber sheet. Each product falls under the broader HS chapters for graphite (chapter 39) and rubber (chapter 40), which are the standard tariff headings used for customs clearance. The supplier’s portfolio reflects a focus on sealing solutions and sheet‑type materials used in industrial applications. The listing does not specify any certifications held by the company, so buyers should verify compliance with relevant standards during procurement.

The eight products are described using generic category names rather than brand or model identifiers. Graphite‑based sheets and gaskets are typically classified under HS code 3919, while silicone, neoprene and general rubber sheets correspond to HS codes in the 4000 series such as 4008 or 4015. The catalogue’s inclusion of both reinforced and spiral wound gasket formats indicates capability to serve high‑pressure sealing needs. By covering both metal‑free graphite and elastomeric rubber sheets, the supplier addresses a range of temperature and chemical resistance requirements. Buyers reviewing the list should cross‑reference each item with the appropriate HS code and material specification for import documentation.

The product list comprises graphite gasket sheet, reinforced graphite sheet, gasket paper material, spiral wound gasket, reinforced graphite gasket, general rubber sheet, silicon rubber sheet and neoprene rubber sheet. In the gasket market, graphite sheets are commonly supplied in grades such as 300 µm to 800 µm thickness, with reinforcement fibers to improve tensile strength, while spiral wound gaskets combine metal carriers with soft filler layers for high‑temperature service. Rubber sheets are usually offered in thicknesses from 1 mm to 10 mm and conform to ASTM D2000 or ISO 37 for hardness and tensile testing. Silicon rubber sheets often meet IEC 60950 for flame retardancy, and neoprene sheets are frequently graded for oil and weather resistance according to ASTM D412.

Industry practice shows that buyers of these sealing materials request data on compression set (typically ≤ 20 % after 70 °C for 24 h), tensile strength (e.g., ≥ 10 MPa for reinforced graphite sheets) and hardness (Shore A 40‑80 for elastomers). Typical certifications include ISO 9001 quality management, CE marking for EU markets, and UL listings for North American applications. Suppliers may also provide material safety data sheets (MSDS) and test certificates that reference standards such as ASTM D573 for thermal aging of rubber. The catalogue’s mix of graphite and elastomeric sheets aligns with sectors that need both chemical inertness and flexible sealing.
