Low Chlorine type of PPS-hb. It is specially used in E/E industry which requires the chlorine content. PPS-hb is high rigidity crystalline polymer that offers high-temperature resistance, innoxious, flame resistance, radiation resistance, solvent resistance, electrical insulation, arc resistance, low water absorption, low mold shrinkage, good dimensional stability and radiation resistance. It's brittle. Therefore, it needs to be modified by some modifier.

Owing to its high performance, it's widely used in medical, electronic/electric industry. Such as: rotproof sealed appliances, plugs, and contactors. It can be modified by different modifiers to make different PPS compounds.
