Angst+Pfister APSOplast® PTFE 125 PTFE + 25% glass fibre
Categories:	Polymer; Thermoplastic; Fluoropolymer; Polytetrafluoroethylene (PTFE); Polytetrafluoroethylene (PTFE), Glass Filled, Molded
Material Notes:	The glass fibres result in increased compressive strength, which is particularly useful at high temperatures. Chemical resistance is only negligibly restricted. The dielectric and anti-adhesion properties are reduced somewhat in comparison with virgin PTFE. This type is unsuitable for non-lubricated sliding functions with a soft steel mating partner due to the abrasive glass fibres. This material is more suited to static applications. Type PTFE GF25 FDA is suitable for contact with foodstuffs. Information provided by Angst + Pfister
