HST221-3 — Polyolefin Heat Shrink Tubing

HST221-3 is part of Allied Wire & Cable’s line of irradiated polyolefin heat shrink tubing. Similar to the other products in this line, HST221-3 tubing is able to reliably insulate and protect electrical componenets from environmental forces. This includes solvents, water, and other common fluids. HST221-3 tubing is also heat resistant for up to 135°C and is also flame retardant. Therefore, HST221-3 tubing can be used in some of the most extreme circumstances while still efficiently protecting wires, cables, capacitors, and resistors. Its polyolefin construction also gives HST221-3 tubing increased flexibility, which allows it to continue to protect cables wrapped around tight corners without the risk of cracking or breaking over time.
