Waterproof moisture-proof odourless non-toxic resistance to low temperature

☆Cold resistance to low temperature performance is good (the lowest temperature can reach 70 ~ 100 ℃)；
☆Chemical stability is good, most alkali erosion (except for the oxidation of acid)；
☆Small water imbibition, good electrical insulation performance；
☆Three-dimensional structure, easy to packing；
☆Shape, size, open mode, can be arbitrary choice。
