SPS - Syndiotactic Polystyrene

Description

Xarec™ syndiotactic polystyrene is a high-performance semicrystalline material that owes its syndiotactic structure and therefore outstanding properties to the polymerisation of polystyrene and a metallocene catalyst.

Its excellent CTI value and low dielectric constant, combined with a low dielectric loss factor, make Xarec™ SPS the perfect choice for many applications in e-mobility, high-frequency applications and data transfer.

Xarec™ SPS offers high dimensional stability, a low specific weight, very good heat and chemical resistance, low water absorption and good surface properties. These features mean that Xarec™ SPS is often used for automotive thermal management, drinking water and food contact applications.

The SPS product family from Idemitsu is suitable for a wide range of applications such as pump parts, bathroom fitting parts, plugs, switches, coil formers, and airline and microwave dishware.
