PBT engineering plastics,also known as thermoplastic polyester plastics,are suitable for use by different processing industries.Generally,additives are added or blended with other plastics.Different proportions of additives can be used to manufacture different specifications.PBT engineering plastics are widely used in electronic appliances,auto parts,machinery,household goods,etc.due to their heat resistance,weather resistance,chemical resistance,electrical properties,water absorption and gloss.PBT products are also used with PPE.PC,POM,PA,etc.are collectively referred to as five general-purpose engineering plastics.
The downstream industries of PBT engineering plastics include automotive,electronics/electrical appliances,and machinery.Connector connectors are bridges between signals.They are an indispensable component for transmitting electronic signals and power connections.PBT's balanced physical properties and prices are in line with The need for a connector.PBT engineering plastics are usually blended with 30%glass fiber as a connector.PBT is widely used due to its mechanical properties,solvent resistance,formability and low price.PBT is not suitable for use on SMT type connectors due to poor solder heat resistance.
The second major use of PBT engineering plastics is to use a cooling fan.The cooling fan is placed in the machine for a long time to help dissipate heat.The physical properties of the plastic are required to be heat-resistant,flame-retardant,insulating and mechanical.PBT is usually added with fiber.30%form application as cooling fan outside frame and fan blade
The third use of PBT engineering plastics is as a winding shaft in transformers and relays,generally 30%injection molding with PBT and fiber.The physical properties required for the bobbin include insulation,heat resistance,solder resistance,fluidity,strength,etc.Suitable materials are phenolic resin,PBT,PA6,PET.
The properties of phenolic resin are good,but their formability is inferior to that of PBT.Therefore,PBT resin is used for products with small size and complicated shape.Although PBT solder has poor heat resistance,it has increased its environmental protection awareness in Europe,America and Japan.The trend of recycling PBT.The automotive industry consumes about 2,200 metric tons of PBT in the automotive industry.Half of the PBT is a PBT/PC alloy with PCs that can be used as a car bumper.In addition,PBT can also be used for window motor casings,locomotive motor parts,and automotive transmission gear boxes.Other PBT other uses,such as 15%glass fiber application as the inner seat and outer casing of the energy-saving bulb base,PBT/PC rubber as the skate sole,others such as relay housing,socket,switch,tuner housing.
