PTFE virgin white 55 Shore D

Virgin PTFE is renowned for its exceptional chemical resistance, non-flammable nature, and outstanding sliding properties, making it ideal for use in chemically aggressive or ultra-clean environments. Its non-elastic structure provides dimensional stability but limits its suitability under high mechanical loads or dynamic stress.

While virgin PTFE offers a wide operating temperature range, users should note its low thermal conductivity, high coefficient of thermal expansion, and relatively low load-bearing capacity when used as a bearing material. These properties should be considered during application design, especially in high-pressure or high-load sealing systems.
