PRECISIONSIL™ offers dimensional stability, durability, excellent tensile strength and low elongation. The products surface friction is much higher than that provided by a fabric coated with PTFE, yet allows the user to retain comparable release characteristics. In fact, some products that may adhere to PTFE coated fabrics may not adhere to silicone coated surfaces. Choose any of a variety of PRECISIONSIL™ colors for use where a surface grip with excellent release is desired.
