PTFE (polytetrafluoroethylene) film is available in several primary types, including skived, cast, extruded, and oriented films. Each type is manufactured through distinct processes, resulting in specific properties suitable for different applications. Skived film offers high strength, cast film provides excellent chemical resistance, extruded film is cost-effective, and oriented film delivers superior dielectric strength.

This article explores the various types of PTFE coatings available for metal parts.

Semi-metallic gaskets offer enhanced sealing performance, durability, and resistance to extreme temperatures and pressures.

Metallic gaskets are crucial sealing components used in high-pressure, high-temperature, and corrosive environments where non-metallic gaskets fail. They function by deforming to fill imperfections between flange surfaces, creating a leak-tight seal. This article explores the main types of metallic gaskets, such as ring-type joints (RTJs), spiral-wound gaskets, and metal jacketed gaskets, detailing their distinct designs, materials, and typical industrial applications. Understanding these variations is key to selecting the optimal gasket for specific operating conditions and ensuring system safety and integrity.

This article provides an overview of the primary categories of non-metallic gaskets.
