TPU Elastomer Material Green Environmental Plastic TPU Rubber Electrical Insulation Cable Sheath Material

Green Environmental TPU, fully known as thermoplastic polyurethane elastomer, is a linear block copolymer composed of soft segment of oligomer polyol and hard segment of diisocyanate-chain extender. It has excellent elasticity, wear resistance, cold resistance, environmental protection and non-toxic characteristics, and can be made by salivation, blowing film, calendering or coating of film. TPU elastomer is widely used in many fields of the national economy because of its excellent performance, and is known as the “fifth largest plastic”.

Green Environmental TPU  elastomer material has the elasticity of rubber and the strength of engineering plastic. The soft segment gives it elasticity so that it behaves like rubber. The hard segment gives it processability making it like plastic. It has better processability and longer Life. Compared with the engineering materials, tpu elastomer cable sheath material the same high strength characteristics. And flexibility and dynamic mechanical properties better.

Feature

  • Good electrical insulation;
  • Low acetaldehyd content, good color,;
  • Stable viscosity and low heavy metal content;
  • Higher strength;
  • Green Environmental TPU elastomer cable sheath material has better barrier, transparency;
  • Good machining performance;
  • With excellent barrier performance;
  • can meet the requirements of hot filling beverage filling below 90ºC. And the bottle deformation rate is low;
  • Through modified TPU, the flame retardant level can reach VO level, no halogen low smoke flame retardant;
  • With flexible and high strength characteristics, hydrolysis and aging resistance;
  • thermoplastic extrusion processing, simple process;
  • the surface fog surface, will not produce precipitation, strong stability;
  • Meet the environmental protection requirements of RoHs and REACH;

Application

  • The oil resistance, water resistance, and chemical resistance of the TPU sheath make it an ideal choice for cables used in marine applications.
  • TPU Elastomer Material Outdoor optical cable sheath materials. Such as pipeline optical cables, direct buried optical cables, underwater optical cables, etc.;
  • Sheaths for industrial machinery and equipment;
