Semi-Rigid Polyolefin Heat-Shrink Tubing: A Comprehensive Guide
Semi-rigid polyolefin heat-shrink tubing is a versatile and widely used material in various industries. It offers excellent electrical insulation, mechanical protection, and environmental sealing for wires, cables, and components. This article will delve into the properties, applications, and advantages of semi-rigid polyolefin heat-shrink tubing.
What is Semi-Rigid Polyolefin Heat-Shrink Tubing?
Semi-rigid polyolefin heat-shrink tubing is made from cross-linked polyethylene or polypropylene. This tubing is designed to shrink to a smaller diameter when exposed to heat, providing a tight and secure fit around the object being insulated. Unlike flexible heat-shrink tubing, semi-rigid tubing retains its shape after shrinking, offering greater structural support and rigidity.
Properties and Advantages
