Based on my experience, this polyolefin insulation shrink tubing is a must-buy for anyone working in industrial and scientific fields. It is designed to provide excellent electric insulation, protection, and strain relief for wires and cables of various sizes. I appreciate its high shrink ratio and easy-to-use features, making it suitable for a wide range of applications. However, it may not be suitable for extreme temperatures and harsh chemical environments. Overall I highly recommend this product for its durability and efficiency..
