Polymide Film with Fluoropolymer Coating

ESONE PI/PTFE composite film is a family of heat sealable fluoropolymer-coated high strength polyimide materials specifically engineered for the aerospace and cable industries.

This composite film offers a balanced range of properties, making it an ideal choice for applications in airframes, hookup wires, and general aircraft wiring. 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.

THV Film

ESONE’s THV (Tetrafluoroethylene-Hexafluoropropylene-Vinylidene fluoride) Fluorothermoplastic, a polymer made from tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride, offers unique advantages such as bonding capabilities with elastomers and hydrocarbon-based plastics, along with flexibility and optical clarity. ESONE THV films, produced via melt extrusion casting from THV resin, exhibit exceptional performance characteristics, including low processing temperatures and excellent flexibility. These films can be heat-sealed, thermoformed, and laminated to various substrates, making them ideal for multilayer hoses, tubes, sheets, and films.

Advantages of THV Foil

• Very high optical clarity and light transmission
• Outstanding flexibility compared to other fluoroplastics
• Good weatherability and UV stability
• Flame retardant and good dielectric properties
• Excellent chemical and permeation resistance
• Bondable to itself and other substrates for multilayer constructions
• Low processing temperatures for co-processing with olefinic plastics and hydrocarbon elastomers

PTFE Casting Film/PTFE Cast Film

ESONE’s PTFE Casting Film is crafted entirely from pure PTFE (Polytetrafluoroethylene) using a cast manufacturing method. This film can be produced as either a multi-layered or single-layer film, making it versatile for a wide range of applications. It is specifically engineered to withstand exposure to chemicals, heat, and mechanical stress, where low friction properties are essential. This makes it particularly suitable for environments where gases or corrosive liquids may be present, especially at elevated temperatures.
