PTFE coated glass fiber fabric is made of high performance glass fiber fabric impregnated with PTFE emulsion. It’s designed for varieties of applications in diverse industries where high temperature, non-stick, chemical resistance and dimensional stability characteristics.

We manufacture many styles of PTFE coated glass fiber fabrics from 0.08mm to 1mm thick. Our PTFE coating percentages range from 15% to over 60% by weight.

We offer PTFE coated woven fiber glass fabric and PTFE coated glass fiber open mesh fabric.

• PTFE coated woven fiber glass fabric: tightly knit glass fiber yarns weaved fabric as substrate material, which is coated with PTFE (Teflon) emulsion.
• PTFE coated glass fiber open mesh fabric: glass fiber open mesh fabric as substrate material, and it is coated with PTFE (Teflon) emulsion.

Main properties

• High-temperature resistance(-100 to +550).
• Non-sticky and easy to clean.
• Food grade and nontoxic.
• Heat resistance and fireproof.
• Resistant to chemical corrosion, strong acid and alkali.
• Good dimensional stability, high strength, and has good mechanical properties.
• Low friction coefficient (0.05-0.1), the best choice for oil-free self-lubrication.
• Light transmittance up to 6%~13 %.
• High insulation property (the value of dielectric constant is only 2.6, and the value of tangent is less than 0.0025).
• Anti-static and Ultraviolet-proof.

Classification

Depending on application requirements, PTFE coated glass fiber fabric can be produced different grades.

• Common industrial grade
  - PTFE coated glass fiber fabric has good heat resistance, corrosion, non-stick properties, mainly used in various industrial fields.
• Standard grade
  - Using imported materials production, in addition to good corrosion resistant properties, the surface is more smooth, flat, non-stick performance is good, both can be applied to general industrial applications, more advantages in some products used plastic stripping or separation sheets, gaskets, off mold surface.
• Food grade
  - Smooth surface, good release properties, heat resistance and easy to clean, use more secure in the food industry.
• Anti-static grade (anti-static cloth)
  - In addition to traditional performance of PTFE coated glass fiber fabric, adding anti static agent when producing PTFE coated glass fiber fabric, so that it has anti-static properties to meet specific customer’s requirements.
