PTFE Films
CHEMFILM PTFE films are used to provide a high temperature, chemical resistant material in a number of applications. Our PTFE films are either skived or cast. Skived film products include premium skived, flex barrier and UHMWPE. These skived films offer up to 60 inch wide webs and superior flatness for the tightest tolerances in the industry. Cast film products include mold release, vacuum bagging, monolayer, cementable adhesive coated, anti-static conductive, and heat weldable films. Our cast films are made up of very thin layers which have been individually deposited, sintered and fused together to produce a material with more uniform properties than can be achieved by any other manufacturing process.

DF100, Type C and Type CD Monolayer Films
CHEMFILM DF100 is a standard gauge multilayer 100% cast PTFE film. CHEMFILM Type C and CD films are ultra-thin, multilayer 100% cast films. Type CD indicates duplex winding (2 film layers wound on a single core).

DF1100 and DF1200 Cementable Adhesive Coated Films
CHEMFILM DF1100 is a multilayer cast PTFE film, fully fused, with one surface modified to render it receptive to many conventional adhesives, elastomers, resins and potting compounds. The surface treatment was developed to assure that its application over pure PTFE would not degrade or discolor the basic film. After surface treatment, the PTFE film loses none of its excellent physical and electrical characteristics. CHEMFILM DF1200 is DF1100 laminated to 2 mils of acrylic pressure sensitive adhesive.

DF1400 and DF1471 Anti-Static Conductive Films
CHEMFILM DF1400 and DF1471 are anti-static, conductive films. CHEMFILM DF1400 is multilayer cast PTFE film with a non-conductive, fully-fused PTFE core and a conductive fluoropolymer formulation on both surfaces of the film. CHEMFILM DF1471 is a multilayer cast PTFE that is fully conductive between both surfaces of the film.

DF1700 and DF1900 Heat Weldable Films
CHEMFILM DF1700 and DF1900 are heat weldable multilayer cast fluoropolymer films produced using a proprietary process. These films have a PTFE core with a thin layer of FEP or PFA on one surface. Double bondable films are also available with PFA on either surfaces or FEP on one surface and PFA on the other surface.

Flex Barrier Films
CHEMFILM flex barrier films are manufactured from high quality, virgin PTFE resins which are molded into billets, sintered and skived to the required thickness with extremely tight tolerance control. Using a specialized modification process, single and multi-layer films are manufactured with significantly improved flexibility and low permeability properties.

MR and VB3 Films for Composite Molding
CHEMFILM MR films, or mold release films, for composite molding combine the chemical inertness and universal non-stick properties of PTFE polymers with maximum conformability and heat resistance. CHEMFILM VB films, or vacuum bagging films, offer an ultra-high temperature, maximally conformable vacuum bagging film for extreme composite molding applications. The high elongation and unmatched drapability allows for superior conformability for irregular shapes, making MR and VB films the ideal solution for composite molding.

Premium Skived Films
CHEMFILM premium skived films are manufactured from the highest quality virgin PTFE resins. These PTFE films offer great electrical properties, and are additionally engineered to meet the requirements of demanding mechanical and chemical needs. Premium skived films offer a non-stick solution with a low coefficient of friction.

UHMWPE Films
CHEMFILM PTFE Films include a range of Ultra High Molecular Weight Polyethylene (UHMWPE) films, engineered for protection in the most demanding applications. UHMWPE films are self-lubricating and abrasion resistant because of their non-stick surface. They are very durable films that are 5 times more abrasion resistant than stainless steel.
