Electrical/Electronic Materials
DeWAL Industries is a leading manufacturer of PTFE (polytetrafluoroethylene) film products used throughout the electronics industry.

DeWAL Industries is an industry leader in the manufacture of quality tapes used in the electrical / electronic industry. Our electrical insulation tape products include substrates of PTFE, Polyimide, glass fiber fabrics, FEP, and polyester films. Combined with a group of proprietary high performance and high temperature adhesive systems, these substrates provide excellent dielectric strength, reliable dimensional and thermal stability along with superior tensile strength.

The DW 904, DW D-Wrap and DW 303 ESD are primarily used in printed circuit board manufacturing applications. DeWAL circuit board tapes are manufactured from the highest quality blue or clear polyester films, coated with clean release silicone adhesive. These tapes conform easily to irregular shapes and allow for superior masking of the most intricate details.

DeWAL Industries takes great pride in the breadth of electrical insulating tapes offered. From simple glass cloth tapes to surface treated skived PTFE to FEP adhesive tapes, DeWAL has the solution for all electrical insulation demands.

The DeWAL Advantage
Since our beginning in 1974, DeWAL, now part of Rogers Corporation, has become an industry leader in the manufacture of high performance polymer films and pressure sensitive tapes. Our films are among the longest and widest splice free lengths in the industry.

DeWAL uses only the highest quality engineered resin blends. Consult your DeWAL Representative for more information.

Hugo DiClemente and Edward Walsh established DeWAL Industries in 1974 to process PTFE resin into film that was seen as the best-made product on the market. Both Hugo and Ed had worked together previously and already had over 20 years of experience under their belt. The original company, located in Hope, RI, employed 3 people, while today DeWAL has grown to over 150 employees in Narragansett, RI. 

The business started processing high quality sintered, skived PTFE films and expanded to include skived UHMW-PE films. Over the 39 years since the beginning in 1974, DeWAL has stayed in the forefront of technology in the fluoropolymer products markets. We not only skive the highest quality PTFE and UHMW films, we also offer a wide array of Pressure Sensitive Tapes, extruded / unsintered PTFE films along with highly technical Expanded PTFE as well as Porous PTFE and UHMW products for a wide range of industries, including:


Over this time DeWAL has never lost focus on the products that the company started with and is considered an industry leader in thin film technology. DeWAL Industries is an ISO 9001:2015 Registered Company, focused on “High Quality Products” and “Innovative Solutions.” Everyone in the DeWAL family of employees is committed to help our customers compete in the ever-growing competitive world market.
