HEAT SHRINK MEDIUM / HEAVY WALL TUBING - ADHESIVE LINED Qualtek Electronics QR3, QRA3 HEAVY WALL POLYOLEFIN TUBING WITH OR WITHOUT HOT MELT ADHESIVE SHRINK RATIO 3:1 Features/Applications QR3 has properties of excellent insulation, environmental sealing and resistance to impact and abrasion. Designed for applications to seal and protect electrical and communication connections. Provides excellent mechanical protection to cable joints and terminations. 3:1 shrink ratio allows it to easily fit over irregular shapes and large connectors. QRA3 is recommended for applications with light cable and wire harnesses that require waterproofing and protection of connector components and encapsulates and seals components within the tubing. Operating temperature: -55°C to +110°C Full recovery temperature: 120°C Standard color: Black, red RoHS Compliant Resistant to UV radiation High electrical insulation Superior mechanical property Technical Data Product Dimensions Property Test Method Typical Data IEC 216 -55°C TO +110°C Tensile Strength ASTM D 2671 > 14 MPa Tensile Strength After Aging (150°C, 168hrs.)
