What is PBT resin plastic granules?
Injection grade PBT (Polybutylene Terephthalate) is a high performance engineering plastic, full name polybutylene terephthalate. It has excellent comprehensive properties, including high mechanical properties, thermal stability, electrical insulation, chemical corrosion resistance, etc. 4. Because of its unique properties, this material has been widely used in the fields of automobiles, home appliances, communication electricians and power tools
The following are the main performance of PBT resin :
1. Heat resistance
PBT has a high thermal deformation temperature, up to 200ºC, and has good heat stability .
2. Mechanical properties
PBT has high strength and hardness, good fatigue resistance, and has good bending strength and rigidity .
3. Electrical properties
PBT has good insulation properties and arc resistance, small dielectric constant, suitable for electronic and electrical fields .
4. Chemical stability
PBT has good acid and alkaline resistance, oxidation resistance and corrosion resistance, and can remain stable in a variety of chemical environment .
5. Processing performance
PBT is easy to form and can be processed into various shapes by injection molding, extrusion, blow molding and other processes, especially suitable for injection molding complex parts.

Injection molding process of PBT granules :
Drying: PBT needs to be dried at 110~120ºC for about 3 hours before injection molding.
Molding processing temperature: generally 250 ~ 270 ºC, mold temperature control at 50 ~ 75 ºC is appropriate.
Cooling time: As PBT from the molten state will immediately solidify and crystallize once cooled, so the cooling time is short.
Note:
If the barrel temperature exceeds 275°C or the melt stays in the barrel for more than 30 minutes, it is easy to cause the material to decompose and become brittle. PBT injection need to use a large water inlet rubber, should not use the hot channel system, mold exhaust should be good, should use high-speed, medium pressure, medium temperature conditions molding processing, fireproof material or glass fiber PBT nozzle material should not be recycled, shut down need to use PE or PP material timely clean the material pipe, so as not to carbonize.
