Our team in the industrial and scientific sector has found the PERFECT solution for our wiring projects using this heat shrink tubing! The flat width of 75mm gave us the flexibility to accommodate various sizes and shapes of batteries, while the PVC material made the shrink wrap very durable.The heat shrinking process was easy and precise, without causing any damage to the batteries. Our only con is that the tubing is a bit expensive compared to other options on the market. Overall, we highly recommend this product for anyone looking for a high-quality heat shrink tubing for wiring projects..
