  PBT plastic refers to a kind of plastic composed of polybutylene terephthalate, also known as polytrimethylene terephthalate
PBT for short
It is a condensation polymer of terephthalic acid and 1,4-butanediol
Together with pet, PBT is called thermoplastic polyester
PBT is milky white, translucent to opaque, crystalline thermoplastic polyester
It has high heat resistance, toughness, fatigue resistance, self lubrication, low friction coefficient, weather resistance and low water absorption, which is only 0
1%
It still maintains various physical properties (including electrical properties) and electrical insulation in humid environment, but has large volume resistance and dielectric loss
It is resistant to hot water, alkali, acid and oil, but it is easy to be eroded by halogenated hydrocarbons
It has poor hydrolysis resistance
It can crystallize rapidly at low temperature and has good formability Characteristics a and mechanical properties of PBT: high strength, fatigue resistance, stable size and small creep (there is little change under high temperature conditions); b
Heat aging resistance: the enhanced UL temperature index reaches 120 ~ 140 ℃ (outdoor long-term aging resistance is also very good); c
Solvent resistance: no stress cracking; d
Water stability: PBT is not easy to decompose in water; e
Electrical performance: 1
Excellent insulation performance (it can maintain stable electrical performance even in humidity and high temperature, so it is an ideal material for manufacturing electronic and electrical parts); 2
Dielectric coefficient: 3
0-3
2; 3
Arc resistance: 120sf, molding processability: injection molding or extrusion of ordinary equipment
Due to the fast crystallization speed and good fluidity, the mold temperature is also lower than that of other engineering plastics
When machining thin-walled parts, it only takes a few seconds, and it only takes 40-60s for large parts 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 retardancy, electrical insulation, molding processability); b
Automobile: 1
External parts: mainly including corner grid, engine heat release hole cover, etc; 2
Internal parts: mainly including endoscope brace, wiper bracket and control system valve; 3
Automotive electrical parts: automotive ignition coil, twisted tube and various electrical connectors
(the number of PBT used in automobiles is less than that of nylon, polycarbonate and polyformaldehyde, but with the emergence of low warpage PBT, it will be more 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, as well as a large number of gears, cams, buttons, electronic watch shell Camera parts (with heat-resistant and flame-retardant requirements) PBT process features PBT must be dried at 110 ~ 120 ℃ for about 3 hours before injection molding
The molding temperature is 250 ~ 270 ℃, and the mold temperature should be controlled at 50 ~ 75 ℃
Because the material will solidify and crystallize immediately after cooling from the molten state, its cooling time is short; If the nozzle temperature is not properly controlled (low), the flow channel (nozzle) is easy to cool and solidify, and the nozzle will be blocked
If the barrel temperature exceeds 275 ℃ or the molten material stays in the barrel for more than 30 minutes, it is easy to cause the material to decompose and become brittle
Large water inlet is required for PBT injection molding, and hot runner system is not suitable
The mold exhaust should be good, and & ldquo; High speed, medium pressure, medium temperature & rdquo; For molding and processing, fireproof material or PBT nozzle material with glass fiber should not be recycled
PE or PP material should be used to clean the material pipe in time during shutdown to avoid carbonization
