Advantages and disadvantages of PBT engineering plastics
PBT plastic data function
1. advantages:
Excellent mechanical function, especially high rigidity and hardness
Good heat resistance, hot deformation temperature up to 180 ℃
Good appearance gloss function, especially suitable for spray free electronic and electrical products
Fast crystallization speed, good fluidity and excellent formability
Good thermal stability, especially low thermal expansion and scale shrinkage
Good chemical, solvent and weather resistance
High dielectric strength and good electrical function
Low hygroscopicity, little impact on Electrical and scale stability
2. defects:
The molecule contains ester bond, which will decompose under the action of strong acid, strong base and water vapor
The data is sensitive to the gap and brittle
