Material Notes:
Thermal properties: Kocetal has excellent heat stability; heat degradation is little under long term and high temperature application, compared to other POM. Maximum applicable temperature of products of Kocetal are short term: 140-150C and long term: 100-120C.Mechanical Properties: Kocetal is an engineering plastic that has excellent strength, stiffness and wear endurance. Also, it offers an excellent balance of several properties. For example, mechanical properties are stable in the practical temperature zone (-50C to 80C), compared to Nylon and PBT resins. Although it has slightly lower initial strength, compared to homopolymer, the long term properties of "elongation at break and impact strength" are superior.Electrical Properties: Kocetal has excellent electrical properties. Its electrical properties, volume resistivity, dielectric constant, dissipation factor and dielectric strength change little with temperature. It also has a feature of good anti-pollution properties on electrical contact. Kocetal has such a permanent anti-static grade that can be applied to the specifics.Chemical Properties: Kocetal has excellent chemical resistance to organic chemicals, oils, fats and detergents. It is also strongly resistant to inorganic chemicals except strong acids.Information provided by US distributor, API-Kolon.
