Expanded PTFE Manufacturer and Supplier

MCP Engineering Plastics Limited are Expanded PTFE suppliers and manufacturers.

Expanded PTFE is manufactured from 100% pure PTFE resin paste extrusion. The expansion process begins with paste extrusion of fine powder PTFE, using typical lubricants or mineral spirits. The lubricant is then completely removed by heat. Expansion can be done by uniaxial or biaxial stretching of PTFE. The biaxial expanded PTFE has an increased tensile strength and improved recovery properties.

Key properties of expanded PTFE:

• Expanded PTFE adapts excellently to the sealing surfaces and compensates for considerable unevenness at changing temperatures and loads
• Chemically inert, hydrophobic, non-flammable, FDA approved.
• Higher permeability to gases and liquids due to its porous structure
• Sealing performance maintained over long term
