Polyolefin tubing is a versatile material commonly used in electrical insulation, automotive wiring, and industrial applications. Made from the polymerization of olefins like polyethylene and polypropylene, it offers exceptional durability, flexibility, and resistance to chemicals and moisture. Its outstanding electrical insulating properties protect wires and cables from corrosion and environmental damage. When heated, polyolefin tubing shrinks tightly around various shapes and sizes, ensuring a secure seal. Lightweight and flame-retardant, it combines strength and safety, making it ideal for both industrial and consumer use.
