German imports of PET stick

PET resin, glass transition temperature is high, crystallization speed, long molding cycle, long molding cycle, mold shrinkage, poor dimensional stability, crystallization forming brittle, heat resistance and low. By nucleating agents and crystallization agents and glass fiber reinforced to improve, PET in addition to the nature of PBT, there are the following characteristics: 1. Heat distortion temperature and long-term use in general engineering plastics thermoplastic temperature is highest; 2. Because heat is high, reinforced PET in a solder bath at 250 ℃ immersed 10s, almost no color distortion, particularly suitable for the preparation of soldering electronic, electrical parts; 3. Bending strength 200MPa, elastic modulus reached 4000MPa, creep and fatigue resistance is also very good, high surface hardness, mechanical properties similar to thermosetting plastic; 4. Since the production of PET used in the production of ethylene ratio used PBT butanediol price is almost half the cost, so PET resin and reinforced engineering plastics PET is the lowest price, with a very high price. Use of glass fiber reinforced PET for electrical and electronic and automotive industries, for a variety of coil skeleton, transformers, televisions, tape recorders and shell parts, automobile lamp, lamp, incandescent lamp, relay, selenium rectifiers. PET plastic consumption ratio currently several application areas are: 26% of electrical and electronic, automotive 22%, 19% machinery, appliances 10%, consumer goods 10%, other 13%. The current total consumption PET plastic is not large, only 1.6% PET total.
