PBT (polybutylene terephthalate) 325M-54018 plastic raw materials: Innovative Plastics (USA) 



 Advantage 

 ☆ a very low moisture absorption 

 ☆ good dimensional stability 

 ☆ even if still in hot or humid environment with excellent electrical performance 

 ☆ excellent chemical resistance 

 ☆ good heat resistance and heat aging properties 

 The ☆ Enhanced specification with high strength and stiffness 

 ☆ easy injection molding, PBT production cycle is very short 

 ☆ good wear resistance 



 PBT as a milky white translucent to opaque, crystalline thermoplastic polyester. Tasteless, odorless, nontoxic, the relative density of 1.31 to 1.32; melting temperature of 224 ~ 228 ℃, the softening temperature of 170 ~ 180 ° C (lower than PET 80 ~ 90 ° C), long-term use temperature of 120 ℃; with high heat resistance, toughness, fatigue resistance, self-lubricating, low friction coefficient, weather resistance, low water absorption of only 0.1% in wet conditions remain a variety of physical properties (including electrical properties), electrical insulation, but the volume resistivity, dielectric big loss. 



 PBT has a high melting point and crystallinity, water absorption and thermal expansion coefficient is very low, so it has excellent dimensional stability. In addition, with excellent electrical insulating properties, small changes in electrical properties caused by moisture absorption, high insulation voltage. Crystalline and amorphous regions of PBT in the aggregation structure, Thus, by adding other substances can easily be modified to give its various functions. Existing flame retardant grade, high-speed molding type grade, high impact grade given to the various functions of the various grades. Connection, small switches, capacitors, shells and other electronic parts, OA machinery keyboard and VTR, telephones, the function of mechanical components, automotive electronic components, door external handle automotive parts. Also, medical equipment, construction materials, precision machinery is widely used in many of our daily supplies appliances
