Polytetra Processors benefits — why PTFE outperforms in corrosive and high temperature service.
PTFE retains its properties after exposure to temperatures beyond the limit of almost all other thermoplastics and elastomers. Depending on end user requirements it is rated for continuous service as high as 500 F and can sustain short exposure higher still.
Extraordinary resistance to high temperature and flames thanks to a very high melting point, high auto ignition temperature and exceptional thermal degradation thresholds. Rate of heat release and smoke generation is very low.
One of the lowest coefficients of friction of any solid material. Abrasion resistance is adaptable to demanding environments using inorganic fillers such as glass fibre, carbon or graphite.
Chemically pure and inert, with no lubricants, stabilizers, plasticizers or antioxidants that can contaminate process fluids.
Extremely low surface energy in the solid state gives an excellent anti-stick, non-wetting contact surface; in molten form the resins become low surface-tension liquids.
PTFE retains its excellent properties even at cryogenic temperatures, with impact resistance exceeding that of most other polymers.
Excellent retention of properties over long periods even at elevated temperatures and in the presence of oils, solvents, UV light and oxidizing agents.
One of the lowest refractive indexes; visual appearance does not change after exposure to ultraviolet or infrared light.
Remarkable dielectric strength, low dielectric constant, low loss factors and high specific resistance across a wide range of environmental conditions.
Inert to microbiological and enzymic attack because the pure polymer provides no nourishment or porosity for growth.
Completely resistant to hydrolysis and a good barrier to water permeation, with dimensional stability unchanged after long periods in water.
