Fre-Thane 85A is one of our most popular tubing products. There are two general classes of polyurethane and both are commonly found in the market: ether-base and ester-base. Chemically, these are made from two different polyol alcohols that cause similar, but different reactions in the isocyanate. From the user's standpoint, the ester-based polymer is less expensive however it degrades when exposed to moisture. Because of this, we manufacture our Fre-Thane® polyurethane tubing using the ether-based material. Freelin-Wade's Fre-Thane has a high resistance to abrasion while being highly flexible and kink resistant. Its most notable quality though is its "memory." Fre-Thane will stretch and flex but always return to its original shape. Freelin-Wade began manufacturing polyurethane tubing in 1980 and it remains our core product today. It is available in 28 in-stock colors and a virtually infinite number of color variations, including clear tubing. Fre-Thane is Freelin-Wade's most versatile product, with more options and variations available than with any other tubing.
