Polytetrafluoroethylene(PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications and makes it one of the best-performing materials in the field of sealing technology. PTFE has one of the lowest coefficients of friction of any solid. Where used as a lubricant, PTFE reduces friction, wear, and energy consumption of machinery.
Broad operating temperature range -200°C to +260°C
Optimum electrical insulating properties and great dielectric properties
Superior longevity, weather-resistant
Excellent frictional characteristics, no "stick-slip"
PTFE is self-lubricating component, which means that bearings and dynamic seals can run dry under certain conditions
Chemical resistance
Non-flammable
Extremely low water absorption
聚合物类型Thermoplastic
材料明细Virgin PTFE

温度范围-200 / +260
耐磨性Low
FDA 认证Yes
耐压强度Low
耐化学性High
Virgin PTFE material is highly resistant to heat, as well as attack from most chemicals. The electrical properties are excellent. Though it's high impact strength, its resistance to wear, durability and creep resistance are low as compared to alternative engineering grade thermoplastics. FDA approved.
