Environmental Friendly TPU Elastomer Cable Sheath Material Environmental Friendly Flame Retardant Thermoplastic Polyurethane

The recycled thermoplastic polyurethane tpu elastomer is a kind of environmental friendly inflaming retarding thermoplastic elastomer cable material.It has excellent  mechanical  performance and  processing  performance,and fine flame retardant  property.It meets IEC-60332-1-1 standard.  TPU elastomer material is widely used in metro,ships,program-controlled machine room of power cable,optical cable,signal cable and various data transmission cable.

Feature

  • Good electrical insulation;
  • Has flame retardant;
  • Low acetaldehyd content, good color,;
  • Stable viscosity and low heavy metal content;
  • TPU Elastomer has higher strength;
  • Better barrier, transparency;
  • Good machining performance;
  • With excellent barrier performance;
  • Tpu elastomer 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;
  • Thermoplastic polyurethane 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.
Outdoor optical cable sheath materials, such as pipeline optical cables, direct buried optical cables, underwater optical cables, etc;
Plastic TPU Sheaths for industrial machinery and equipment;
