                PBT

                 
                Introduction to Materials:Poly (butylene terephthalate), of PBT for short, is a polyester series, 1.4-the pbt butanediol (1.4-Butylene glycol) and terephthalic acid (PTA) or polyethylene terephthalate (DMT)condensation, made through the mixing process and milky white translucent to opaque, crystalline thermoplastic polyester resin. Collectively referred to as a thermoplastic polyester or unsaturated polyester and PET.

                Performance Profile:PBT as a milky white translucent to opaque, crystalline thermoplastic polyester. 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, volume resistivity, dielectric, dielectric loss. Heat water, alkali, acids, oils, but are vulnerable to erosion of halogenated hydrocarbons, poor resistance to hydrolysis, rapid crystallization at low temperatures, good formability. The disadvantage is that the notched impact strength, mold shrinkage. Therefore, most of the glass fiber reinforced or inorganic filler modified the tensile strength, bending strength can be increased more than doubled the thermal deformation temperature has significantly increased. At 140 ℃ for long glass fiber reinforced products, vertical and horizontal shrinkage inconsistent, easy to make products warpage.

                Market applications:PBT has been widely used in automobiles, electrical equipment, machinery, structures: transport equipment, textiles, paper making machinery, etc..

                Product categories and use:
                Product Category Use of Specific uses
                Enhance the flame-retardant PBT Electronics, consumer electronics Auto ignition / heater automatic control of electrical appliances, electronic vitality of high voltage parts, electronic connectors, etc.
                Resistant UV retardant PBT Electronics, industrial electronics Instrumentation, connectors, relays, junction boxes, switch parts, coil skeleton, lighting components, the car handles, door latches, etc.
                Low precipitation resistance PBT High breaking Reed automatic control of electrical, electronic vitality, high voltage parts, electronic connectors, etc.
