Detailed Product Description

Characteristic

PPS-hb1 has processed by screw granulation which has higher apparent specific gravity than hb0. It 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. Its brittle. Therefore, it needs to be modified by some modifier.

Applications

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.

Properties

Remark: The statistics above are typical value, not be proved as receiving inspection standard.
