Kaxite Sealing is a premier China-based manufacturer and supplier of molded PTFE sheet gaskets (Model KXT PMS) – high‑quality gaskets produced from compression‑molded PTFE sheets with exceptional chemical resistance, low friction, and wide temperature tolerance. Our molded PTFE sheet gaskets are available in virgin, modified, and filled grades (glass, carbon, graphite, bronze, etc.) to meet specific mechanical and thermal requirements. They can be furnished with sodium ammonia or sodium naphthalene surface etching on one or both sides to ensure excellent bonding to flange surfaces, making them ideal for demanding applications in chemical processing, electronics, heavy electricals, valves, pumps, and more. With thicknesses up to 50 mm and custom sheet sizes, we provide tailored gasketing solutions for critical service conditions.
As a trusted factory direct supplier in China, Kaxite offers custom sizes, surface etching, and filled compounds at competitive wholesale pricing. Request your price list and free sample →
Molded PTFE sheets – available in various thicknesses and sizes
Astonishing resistance to almost all chemicals – ideal for corrosive media.
From -200°C to +250°C – suitable for cryogenic and high‑heat services.
Excellent insulation – ideal for electronics and heavy electricals.
Lowest coefficient of friction of any solid material – reduces wear.
* Custom thicknesses, filled compounds, and etch patterns available. Contact our technical team.
Our molded PTFE sheet gaskets can be furnished with sodium ammonia or sodium naphthalene etching on one or both surfaces. This chemical treatment modifies the PTFE surface, creating a microscopically rough and chemically active layer that enables excellent adhesion to flange surfaces, coatings, or adhesives. This is particularly beneficial for applications where gasket movement or blowout resistance is critical. Custom etch patterns and partial etching are also available.
* Etching services available upon request – inquire with our sales team.
Molded PTFE sheet gaskets are die‑cut or custom‑fabricated gaskets produced from compression‑molded PTFE sheets. They offer the same outstanding properties of PTFE – chemical inertness, low friction, wide temperature range – and can be tailored in thickness, size, and filler content to meet specific application requirements.
Etching creates a chemically active, roughened surface that allows adhesives, coatings, or flange surfaces to bond securely to PTFE, which is otherwise non‑stick. This prevents gasket displacement and improves sealing reliability under high pressure or vibration.
We offer thicknesses from 1.5 mm up to 50 mm, with custom thicknesses available on request. Sheet sizes can be up to 1500×1500 mm or custom dimensions.
Yes, we offer glass‑filled, carbon‑filled, graphite‑filled, bronze‑filled, and other compounds to enhance mechanical strength, wear resistance, and thermal conductivity. Please specify your requirements when ordering.
Yes, our virgin PTFE grades comply with FDA 21 CFR 177.1550 and are suitable for food, beverage, and pharmaceutical contact applications. Filled grades may require additional validation.
