Versafit V4 Very-thin-wall, highly flame-retardant, metric-sized heat-shrinkable tubing Versafit V4 heat-shrinkable tubing is a cost-effective, environmentally friendly choice for many commercial applications. Versafit V4 tubing is a very thin-wall version of Versafit, a specially formulated polyolefin with low recovery temperature, excellent flexibility, and high flameretardance (VW-1). Versafit V4 tubing is typically applied where space savings is important, offering the ability to pack components more closely than is possible with standard tubings. Versafit V4 tubing can shrink more than twice as fast as standard products. This rapid shrinking may be important in the prevention of overheating of temperature-sensitive components. PBBs PBBOs and polybrominated biphenyl oxides (PBBOs). In Europe, these chemicals are classified as environmentally hazardous substances. Versafit V4 products are UL-recognized at 125°C, 300 V, and CSA-certified at 125°C, 150 V, with UL VW-1 and CSA OFT flame-retardancy ratings. Unlike other typical flame-retardant tubings, Versafit V4 tubing is free of polybrominated biphenyls (PBBs) Temperature rating Full recovery temperature: Continuous operating temperature: 90°C –45°C to 125°C Specifications* ® Type Versafit V4 Raychem RW-3023 UL E35586 VW-1 CSA LR31929 VW-1 *When ordering, always specify latest issue.
