PBT
Key words:
PBT material molecules are relatively easy to slip, easy to orientation, crystallization, resulting in large shrinkage of the material, causing warping deformation of PBT parts, especially large thin-walled parts. For glass fiber reinforced PBT, due to the anisotropy of the added glass fiber, the shrinkage rate of the material is different in different directions in the injection molding, which increases the warping deformation of the parts, which not only affects the surface quality and installation performance of the plastic products, but also affects the strength of the plastic.
Key words:
PBT is a polyester material with excellent physical properties and chemical stability, which is widely used in electronics, automobiles, home appliances and other fields. With the development of science and technology, the application prospect of PBT in more fields will be more broad. PBT is widely used in the insulation materials of electronic components, such as sockets, connectors, insulators, etc. PBT is more and more widely used in auto parts, such as lights, instrument panels, electronic control modules, etc. PBT is used in the manufacture of household electrical appliances shell, switch, socket and other components, with good heat resistance and weather resistance.
