PBT is a milky white translucent to opaque, crystalline thermoplastic polyester. Has the advantages of high heat resistance, toughness, fatigue resistance, self lubrication, low friction coefficient, weathering resistance, low water absorption rate, only 0.1%, in the humid environment remains properties (including electrical properties), electrical insulation, but the volume resistivity, dielectric loss. Water resistance, alkali, acid, oil, halogenated hydrocarbons but are vulnerable to erosion, hydrolysis resistance, low temperature crystallization can be rapidly, good formability. Drawback is the low impact strength, high mold shrinkage. It is mostly filled with glass fiber reinforced or inorganic modification, the tensile strength, bending strength can be increased one times above, thermal deformation temperature is also significantly improved. Can work at 140 ℃, glass fiber reinforced products longitudinal, transverse shrinkage is not consistent, easy to make the product warpage.
Applications:Electrical/Electronic Applications;General Purpose.
