Thermoplastics SKF Ecotal Special materials
SKF Ecotal is a semi-crystalline polyacetal- All standard materials can be modified to
SKF Ecoptfe copolymer (POM) which is used for anti meet specific application requirements .
SKF Ecoptfe is a thermoplastic material extrusion rings, guide rings, bushings and Contact SKF for more information .
based on polytetrafluoro-ethylene (PTFE) scrapers . This material has good mechanical
with 15% glass fibre and 5% graphite . It is proper ties, low water absorption and good
mainly used for back-up rings, selected lip chemical resistance . It can be used in mineral
seals and buffer seals . It has outstanding oils and in water-based, fire-resistant
chemical and temperature resistance . hydraulic fluids (HFA, HFB and HFC) .
Thanks to the fillers, this material has
optimized compression strength and sliding
properties .
