HEATSHRINKABLE SELF-EXTINGUISHING TUBING IN POLYOLEFIN ?SERIES STP125? SHRINK RATIO 2 ÷ 1
GENERAL FEATURES
Series STP125 polyolefin tubing is a self-extinguishing heatshrinkable tubing with excellent physical and electrical properties. It is ideal for general protective covering, cabling and insulation and thanks to the simplicity with which it shrinks it adapts very easily to the item being covered.
