Introduction to Sabit American DuPont PBT Crastin SK615SF:
Polybutylene terephthalate, also known as polytetramethylene terephthalate. Abbreviated as PBT. It is a polycondensate of terephthalic acid and 1,4-butanediol. Together, PBT and PET are known as thermoplastic polyesters.
Sabit American Dupont PBT Crastin SK615SF Features:
a. Mechanical properties: high strength, fatigue resistance, dimensional stability, and small creep (very little change under high temperature conditions);
b. Heat aging resistance: the enhanced UL temperature index reaches 120~140°C (the outdoor long-term aging resistance is also very good);
c, solvent resistance: no stress cracking;
d. Water stability: PBT is not easy to decompose when it meets water;
e. Electrical performance:
1. Insulation performance: excellent (it can maintain stable electrical properties even under humidity and high temperature, and 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 with ordinary equipment. Due to the fast crystallization speed and good fluidity, the mold temperature is lower than other engineering plastics. When processing thin-walled parts, it only takes a few seconds, and it only takes 40-60s for large parts.
Sabit American DuPont PBT Crastin SK615SF Application:
a. Electronic appliances: connectors, switch parts, household appliances, accessory parts, small electric covers or (heat resistance, flame retardancy, electrical insulation, molding processability);
b. Car:
1. Exterior parts: mainly corner grille, engine heat release escutcheon, etc.;
2. Internal components: 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 be more used in automobile parts in the future)
c. Mechanical equipment: belt drive shafts of video tape recorders, electronic computer covers, mercury lamp covers, electric iron covers, baking machine parts, and a large number of gears, cams, buttons, electronic watch cases, and camera parts (with heat resistance, flame retardant requirements)
