RAYCHEM SCT Adhesive-lined, semirigid, polyolefin heat-shrinkable tubing (extended temperature range) SCT is a high-quality, dual-wall tubing SCT has a tough outer wall made of This barrier provides exceptional designed to insulate and seal radiation crosslinked, flame-retardant, protection against corrosion. automotive wire splices and semirigid polyolefin. The inner wall is components made by ultrasonic a unique, specially formulated hot- Because SCT has a high shrink ratio, welding, clip-and-dip, or soldering. melt adhesive designed to function at only a few sizes are needed to cover Typical applications are insulating and an extended temperature range. The a wide range of splice and sealing splices in an under-the-hood adhesive forms an outstanding barrier component diameters. automotive environment. against moisture and automotive fluids.
