Polystone® P SK/GK

Polystone® P SK/GK is an isotactic, highly heat-resistant polypropylene homopolymer (PP-H) grade by Rochling Engineering Plastics. Is available in natural, grey and special colors. Due to backing on one side, it can be bonded with other materials. The material used for the backing is either a polyester stretch (SK) or knitted glass fiber (GK), in case of strongly diffusing chemicals and/or high temperature fluctuations. Exhibits excellent weldability, processability, high adhesion in a composite system and high chemical- & corrosion resistance. Polystone® P SK/GK is suitable for processing by extrusion and designed for extruded sheets and coils. Used in chemical engineering, tank building, galvano technology, relining, corrosion protection and re-construction. Complies with UL 94 HB flame rating.
