Brief introduction:

PC-PBT [1] is a blend of PC and PBT, usually supplied with pellet shape after blending. If we simply mix the two materials directly after injection, the effect will be very poor, and there will be stratification.

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. The advantage of PBT is that its rigidity is not affected by temperature and its deformation is small. Thus, PC-PBT retains the advantages of both.

PC-PBT has higher surface hardness, higher rigidity and toughness, higher resistance to high temperature shape, and higher resistance to stress cracking; its mechanical properties are between the two.

High temperature resistant deformation is of great significance for large shell materials.
