    2.Product Description
    2.1Properties:
    The series of products are made of the basic material polyolefin resin and auxiliaries such as halogen-free flame retardant and antioxygen, with the process of mixing, plasticizing and pelleting. The halogen, heavy metal, PBB and PBDEs content of the environmental-friendly products meet the EU environmental protection requirement (RoHS directive), according to the detection of SGS Company. The series of products are of good mechanical, physical, electrical, flame retardant and processing properties. The products can no crackles low temperature (-25℃) embrittlement tests.
