TPE plastic raw material:
1, Type and application:
Non-flame retardant.USB connecting line,amarok line, earphone line, cellphone charger line,data cable, UL wire, power line and other flexible requirement.
2, Introduction
TPE is the material which is combined with the rubber and plastic
It produce different cable products by intruding, molding
With properties of flame-retardant, abrasion–resistant, aging-resistant, UV proof, cold-resistant, excellent electrical property, smooth and round surface
Can be applied to wires, power line and connector plug
Its properties can meet the UL1581/UL758 requirement and its environmental properties can meet the laws and regulation of RoHS, Sony SS00259 and REACH requirements
3,Processing:
Intruding processing: it should be processed by the normal intruder, which screw L/D≥20
It is better to use the low compression ratio low smoke halogen-free screw
The following temperature (°C) profile of extruder is recommended:

Note: recommended dried the materials 2 to 4 hours in the temperature 80°C before using it
4, Storage and transport:
25kg/bag, PE membrane inside bag, and Kraft outside bag
Storage and transport: avoiding in direct sunlight and weathering
The storage place should be in clean, cool, dry and ventilated conditions
