Coated on both sides with fluoropolymer materials(including PTFE coating, PFA coating or FEP coating) tailored for the wire and cable sector, ESONE composite films are compatible with wire constructions that include tin, silver, and nickel-plated conductors, as well as copper conductors.

The ESONE composite film comprises polyimide (PI) coated with fluoropolymer resins such as PTFE or PFA or FEP. It boasts excellent thermal, chemical, mechanical, and electrical insulation, along with outstanding release properties, making it suitable for various demanding applications.

Semi-Conductive Black UHMW Film (ultra-high molecular weight polyethylene) is designed for general applications requiring release, non-stick properties, or enhanced robustness. These films offer superior abrasion resistance and durability under mechanical stress, along with self-lubricating characteristics similar to Skived PTFE Films. Their anti-stick surface and sound-deadening properties make them ideal for demanding applications.

Additionally, Skived UHMW-PE Films can be bonded without etching, using methods such as thermal activation or bonding agents. UHMW exhibits exceptional abrasion resistance, often surpassing that of steel. With broad chemical resistance and a low coefficient of friction, UHMW serves as a versatile engineering material suitable for severe duty applications.

Characterized by its slipperiness akin to PTFE, UHMW polymers possess a molecular weight average ten times greater than that of conventional high-density polyethylene resins, enhancing their performance in various applications.
