Commentary

A polymer consisting of benzene rings linked by sulfur, produced by polycondensation of paradichlorobenzene and sodium sulfide. It is a material with good flowability and is easily reinforced with filler. 40% glass fiber grades is the standard.

Key points

Unreinforced products are easily cracked by impact. Therefore, many grades are reinforced with fillers such as glass fiber.

Filler-reinforced products have good mechanical properties and are chemically resistant, heat resistant, and flame retardant.

Since the main chain contains sulfur, corrosive gases may be generated during high-temperature molding.

使われ方
