PBT Virgin Plastic
Product Details
PBT virgin plastic
a. Mechanical properties: high strength, fatigue resistance, dimensional stability, and small creep (very few changes under high temperature conditions);
b. Heat aging resistance: the enhanced UL temperature index reaches 120~140℃ (long-term outdoor aging is also very good);
c. Solvent resistance: no stress cracking;
d. Stability to water: PBT is not easy to decompose in water;
e. Electrical performance:
1. Insulation performance: excellent (it can maintain stable electrical performance even under humidity and high temperature, it is an ideal material for manufacturing electronic and electrical parts);
2. Dielectric coefficient: 3.0-3.2;
3. Arc resistance: 120s
f. Molding processability: injection molding or extrusion molding by ordinary equipment. Due to the fast crystallization speed and good fluidity, the mold temperature is also lower than that of other engineering plastics. When processing thin-walled parts, it only takes a few seconds, and it only takes 40-60s for large parts.
2. Application of PBT (usually refers to modified varieties);
a. Electronic appliances: connectors, switch parts, household appliances, accessory parts, small electric covers or (heat resistance, flame resistance, electrical insulation, molding processability);
b. Car:
1. Exterior parts: mainly include corner grids, engine vent cover, etc.;
2. Internal parts: mainly include endoscope stays, wiper brackets and control system valves;
3. Automotive electrical parts: automotive ignition coil twisted tubes and various electrical connectors, etc.
(The number of PBT used in automobiles is less than that of nylon, polycarbon and polyoxymethylene, but with the emergence of low-warpage PBT, it will definitely be used in automobile parts in the future)
c. Mechanical equipment: belt drive shaft of video tape recorder, electronic computer cover, mercury lamp cover, electric iron cover, baking machine parts and a large number of gears, cams, buttons, electronic watch casings, camera parts (with heat resistance, Flame retardant requirements)
