Using our specially-formulated sodium naphthalene solution, we’ve been able to corrode the bonding surface of PTFE, obtaining a rough, reddish-brown surface that can be easily adhered to with ordinary adhesives like epoxy. This solution opens up new possibilities for using PTFE in composite applications, making it a more versatile and cost-effective material option.
Our Etched PTFE Sheet comes in a unique reddish-brown color and is highly adhesive, making it suitable for a wide range of applications. Its increased adhesive properties make it perfect for use in waterproofing applications, electrical insulation, and even in the food and beverage industry.
We understand how difficult it can be to find suitable PTFE materials for your specific needs. That’s why we’ve created this innovative product to help you overcome some of the challenges posed by PTFE’s smooth surface. With the Etched PTFE Sheet, you can be confident that your project will be completed to the highest standard.
Our team is dedicated to providing you with the best quality products and services. We’re also committed to maximizing your user experience while maintaining a sustainable and eco-friendly approach to producing our products.
