Product Description

Supply chemical resistant PC-PBT to withstand low temperature impact JH-5220U

PC-PBT is a blend of PC and PBT, usually supplied with pellets after blending. If only two kinds of materials are simply mixed, the effect of direct injection is very poor, and there will be delamination phenomena of chemical and physical characteristics: PC/PBT has comprehensive characteristics of PC and PBT, such as high toughness and geometric stability of PC, chemical stability, thermal stability and lubrication characteristics of PBT, etc. The advantage of PC is that the room temperature is rigid and tough, but the thermal deformation is serious under high temperature. The disadvantages of PBT are stress cracking and high viscosity, its rigidity is not affected by temperature and its deformation is small, so the blended material PC-PBT retains the advantages of both PC-PBT, which has higher surface hardness, higher rigidity and toughness, higher resistance to high temperature deformation and higher resistance to stress cracking. Its mechanical properties lie between the two and the high temperature deformation resistance is of great significance for large shell materials.

Typical application area: the application feature of automotive exterior parts is to replace steel with plastic and reduce vehicle weight. Automotive exterior accessories include front and rear bumpers, hood, radiator grille, fender, door handle, rear guide plate, body decoration strip, etc. In addition to the function of interior decoration, exterior decoration also requires high strength, high toughness, environmental resistance and impact resistance. Polyester (PBT) and polyester/polycarbonate alloy (PBT/PC), especially elastomer toughened PBT/PC alloy and PET/PC alloy are ideal materials for automotive exterior decoration. They are suitable for making automotive body panels, side guards, fenders, door frames, etc. PC+PBT is a plastic alloy, which maintains the chemical resistance and easy formation of crystalline material PBT, as well as the toughness and dimensional stability of amorphous material PC. Gear boxes, automobile bumpers and products requiring chemical reaction resistance and corrosion resistance, thermal stability, impact resistance and geometric stability. Its products are widely used in car bumpers, car handles, car interior parts, vacuum cleaner shell, electronic components, communication equipment, lighting equipment and so on. PC/PBT has comprehensive characteristics of PC and PBT, such as high toughness and geometric stability of PC, chemical stability, thermal stability and lubrication characteristics of PBT.
