Shrinks to 1/2 its original diameter. Fabric heatshrink tubing, a unique mixture of polyolefin and polyester yarns, is the ideal way to form the only shrinkable fabric of its kind. The woven construction makes this product extremely flexible and resistant to trapping water, heat, and humidity. Provides outstanding abrasion, chafing, and cutting protection, even at high temperatures. Shrinkflex fabric tubing is designed primarily to provide mechanical abrasion protection for components such as rubber hoses, plastic pipes, and harness wiring bundles. Also suitable for other applications, such as noise and rattle suppression.
