Product Description
Meteial properties of MIPS strongly depend on the content and particle size of rubber, bonding strength between rubber and matrix, and homogeneity. Generally MIPS retain medium level of mechanical properties between GPPS and HIPS. Due to high impact strength and glossiness, LG chemical MIPS can be applied to several products especially in electric/electronic components, toys, stationary articles, and food containers.
