Teflon coated high-temperature cloth is a composite material made of high-performance glass fiber cloth as the substrate and coated with polytetrafluoroethylene (PTFE, commonly known as Teflon) on the surface. It combines the mechanical strength of glass fiber cloth with the excellent chemical properties of Teflon, and performs well in extreme environments such as high temperature and strong corrosion.

The core performance characteristics and application advantages of Suzhou Mitai PTFE coated high-temperature cloth are summarized as follows:

Performance characteristics

Excellent high temperature resistance with a wide operating temperature range: it can be used for a long time at extreme temperatures ranging from -70 ℃ to 260 ℃ (some products can reach up to 300 ℃), with short-term temperature resistance even higher.

Excellent thermal stability: Dimensional stability in high temperature environments, not easily deformed or decomposed, ensuring the reliability of equipment operation.

Excellent chemical stability and strong corrosion resistance: it can almost resist the erosion of all strong acids, strong bases, organic solvents, and chemical drugs, and is suitable for corrosive environments such as chemical and pharmaceutical industries.

Good anti-aging performance: it is not easy to age after long-term exposure to chemical media, and has a long service life.

Excellent non stick and easy to clean surface with low friction coefficient: The PTFE coating has a smooth surface and an extremely low friction coefficient (0.05-0.1), exhibiting excellent non stick properties.

Easy to clean: Adhesive substances such as oil stains, resins, and coatings can be easily removed, reducing downtime for maintenance and improving production efficiency.

Excellent electrical insulation performance, low dielectric constant: dielectric constant of about 2.6, high breakdown voltage, suitable for high-frequency circuits, electronic components and other fields with high insulation requirements.

Anti static: Some products are treated with special processes to have anti-static functions, meeting the special needs of industries such as electronic manufacturing.

Good mechanical performance, high strength and dimensional stability: Glass fiber substrate endows the material with high tensile strength and tear resistance, with an elongation coefficient of less than 5 ‰ and excellent dimensional stability.

Good flexibility: bendable and foldable, suitable for wrapping or cushioning complex shapes.

Fireproof and environmentally friendly flame retardant performance: Complies with UL94 V-0 flame retardant standards, self extinguishing upon ignition, and high safety.

Environmentally friendly and non-toxic: certified by FDA, RoHS, etc., it can directly come into contact with food and is suitable for food processing, medical devices, and other fields.
