RPC / ABS alloy material combines the excellent properties of PC and ABS, and compensates the physical defects of ABS and PC. due to the poor heat resistance and strength of ABS material, and the high viscosity of PC affects the processability and the stress cracking resistance of products are relatively poor, so ABS processability and rubber are used to compensate for stress cracking defects. Therefore, on the one hand, PC / ABS alloy material can provide the impact resistance, heat resistance and rigidity of thin-walled products of ABS, on the other hand, it can improve the melting fluidity, processability, electroplating ability and appearance of ABS.
