Cast PTFE Films

Versiv PTFE cast films have a special multi-layer construction comprised of various layers configured with different polymers and polymer blends, which can be customized to meet your unique needs.multilayer films manufactured using a proprietary process and can be customised to meet specific application requirements.

Their unique construction is inherently void- and pinhole-free, while delivering the intrinsic properties of PTFE in an isotropic manner, with consistent performance in all directions.

This combination provides excellent dielectric properties, conformability and reliability, making the films ideally suited to a wide range of niche applications.

Key Properties of Cast PTFE Films

Isotropic properties: Uniform mechanical performance and dimensional stability in both the machine and transverse directions.

Minimised defects: Multi-layer construction reduces voids and pinhole defects.

High-temperature resistance: Suitable for continuous service temperatures up to 260°C (500°F), while maintaining release performance across a range of substrates.

Excellent conformability: Conforms readily to irregular shapes, making it ideal for mould-release applications, including at elevated temperatures.

Excellent chemical resistance: Resistant to almost all common chemicals.

Low coefficient of friction

Tight dimensional tolerances

Available in a range of colours

Common Applications

Static control in various manufacturing
Anti-static conductive provides a protective, insulating, and non-stick layer that helps manage and dissipate static electricity while offering durability and resistance to various environmental factors. Used in a wide range of industries, including electronics manufacturing, cleanroom environments, and places where static control is essential for safety and product quality.

Vacuum bagging
Non-stick properties, heat and chemical resistance, and flexibility make them essential for creating a controlled and efficient environment for consolidating and curing composite materials, resulting in quality finished products. Crucial for easy removal of vacuum bag once curing complete.

When used as vacuum bagging films, they excel due to performance at ultra-high temperatures (315°C / 600°F) and are highly comfortable (with 550% elongation).

Manufacturing processes (Mold release)
By providing non-stick, low friction surface that promotes easy release of molded parts.

Heat weldable
PTFE Cast Films promotes smooth and consistent welding processes. Their use leads to improved weld quality, reduced equipment maintenance, and enhanced safety, making them a valuable tool in various welding operations throughout industry.
