Single-Wall Heat Shrink Tubing
K125 and YJK135 are irradiation-cross-linked polyolefin single-wall tubings with a 2:1 shrink ratio. K125 covers general harness insulation; YJK135 is produced for military programs at 135 °C with high flame retardance. Both are used for terminal insulation, solder-joint protection and component covering.
