Material Notes:
A Fluoropolymer used mainly for its excellent chemical resistance. It has poor mechanical features. The strain, even under low weight, makes it very suitable as a gasket material.Features:Chemical: a typical fluoropolymer with very high chemical resistance. Mechanical: the mechanical features such as tensile stress and compressive strength are poor. Notably the bearing strain is very low.Very good resistance to low and high temperatures up to 260° C. as well as to UV rays.Low flammabilityLow friction coefficientColour: naturalWeak Point:Poor mechanical properties. The strain is very high, even simply under the weight of the piece.Application:Chemical: very high chemical resistance to alkali and acids is the main feature of the fluoropolymers. PTFE is used for parts in the petrochemical and chemical industries.Food contact: physiologically inert it is approved for use in contact with food by some standards, whilst in some countries this use is questioned.Electrical: very good dielectric, self-extinguishing and weather stability properties make it suitable for this field.Mechanical: the low friction coefficient makes it suitable for bearings, provided that they work under low charge.Information provided by Omnia Plastica s.p.a. for semifinished products such as sheet, rod, and tube.
