Glass fiber needle punched felt is a new type of fabric with excellent heat resistance and corrosion resistance, which can be used to manufacture various high-temperature heat-resistant felt with good thermal stability and corrosion resistance. The application range of fiberglass needle felt is very wide, including electronics, home appliances, aerospace, automotive and other fields. It can be used for manufacturing heat pipes, heat cables, heat pipe clamps, heat pipe sheaths, etc; It can be used for manufacturing spark plug dust covers, spark plug clamps, turbocharger heat pipes, cooling system heat pipes, and turbocharger heat pipe clamps, etc; It can be used to manufacture heat pipe insulation layers, heat pipe sheaths, insulation felt, and heat pipe shields. In addition, fiberglass needle felt can also be used to manufacture heat pipe sheaths, heat pipe covers, heat pipe covers, turbocharger heat pipes, heat pipe insulation layers, heat pipe sheaths, insulation felt, etc.
