Polyester tubing heat-shrinks at lower temperatures than other shrink tubing, thus reducing the risk of heat-damaging components in devices such as medical equipment. New sizes of ultra-thinwall, high-strength tubing rapidly shrink by 5% or less at temperatures as low as 185°F, and by up to 15% at 200 to 300°F.
