Overview

Expanded PTFE gaskets come in a complete range of specifications, including V-shaped, U-shaped, and L-shaped according to the different inner core structures. In the petroleum, chemical, pharmaceutical, and food industries, some containers, pipelines, and valve connections are often sealed with polytetrafluoroethylene gaskets to ensure material cleanliness.

Product Details

Expanded PTFE gasket with complete specifications

PTFE flange gasket is a non-metallic gasket generally composed of a coating layer and an embedded material. The coating layer mainly serves the purpose of corrosion resistance and is usually made of polytetrafluoroethylene material. The embedded material (filler) is a non-metallic sealing material with or without a metal reinforcement layer, usually asbestos rubber sheet, which has good elasticity. The sealing gasket is divided into V-shaped, U-shaped, and L-shaped according to the different core structures. In the petroleum, chemical, pharmaceutical, and food industries, some containers, pipelines, and valve connections are often sealed with polytetrafluoroethylene gaskets to ensure material cleanliness.
Application scope of PTFE flange gasket:
It is widely used for sealing various strong acids, strong bases, strong oxidants, and non polluting media.
Application of PTFE combination sealing ring product: This material product has the characteristics of acid and alkali resistance, high temperature resistance, and resistance to various organic solvents. Widely used in the chemical and pharmaceutical industry, it can be regarded as the leader in the gasket industry. Used for sealing the piston and piston rod of reciprocating ultra-high pressure hydraulic cylinders.
Scope of application: Hydraulic cylinders for metallurgy, mining, and general equipment.

High temperature resistance - operating temperature up to 250 ℃.
Low temperature resistance - with good mechanical toughness; Even if the temperature drops to -196 ℃, it can maintain a 5% elongation rate.
Corrosion resistance - exhibits inertness towards most chemicals and solvents, and can withstand strong acids, alkalis, water, and various organic solvents.
High lubrication - refers to the coefficient of friction in solid materials.
Non adhesive - refers to the small surface tension in solid materials that does not adhere to any substance.
Non toxic - physiologically inert, implanted as artificial blood vessels and organs without adverse reactions.
