FEP Film
FEP film is a transparent fluoroplastic with unique properties, such as high-temperature resistance (204°C), chemical resistance, extreme non-stick surface, UV stability, non-flammability, high electrical insulation, and high light transmittance.
We offer high quality FEP films with the following features:
- 0.012mm - 0.5mm thickness
- 50mm - 1200mm width
- High transparent
- Roll and sheet options
- Surface treatment
FEP Film Grades
High-Performance Grade
- Excellent chemical resistance and electrical insulation.
- Works well in extreme temperatures.
- Ideal for semiconductor and pharmaceutical uses.
Mold Release Grade
- Smooth surface for easy part removal from molds.
- Reduces friction and resists heat.
- Common in molding processes for plastics, rubber, and composites.
Welding Grade
- Optimized for heat sealing, bonding, and welding applications.
- Provides strong, uniform welds.
- Used in sealing and bonding chemically resistant materials.
Available Shapes
FEP Film Roll
- Comes in rolls, typically used for applications requiring continuous, flexible material.
- Thinner and more flexible than sheet forms.
- Due to the roll format, FEP film in this form is more suited for wrapping, covering, and coating complex or large surfaces.
FEP Film Sheet
- Available in flat sheets, which are more rigid and typically used for cutting or forming into specific sizes.
- Thicker than rolls, offering more rigidity and easier handling.
- Often used in industries where need the specific size film, such as in semiconductor manufacturing or laboratory equipment.
