RAYCHEM SWFR X4 Very-thin-wall, highly flame-retardant, zero halogen, metric-sized heat-shrinkable tubing SWFR X4 tubing is typically applied where space savings is important, offering the ability to pack components more closely than is possible with standard tubings. SWFR X4 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. SWFR X4 heat-shrinkable tubing is a cost-effective, environmentally friendly choice for many commercial applications. SWFR X4 tubing is a very-thin-wall version of SWFR, a specially formulated polyolefin with low recovery temperature, excellent flexibility, and high flame-retardance (VW-1). Unlike other typical flame-retardant tubings, SWFR X4 tubing is halogen free. SWFR X4 products are UL-recognized at 125°C, 300 V, and CSA-certified at 125°C, 300 V, with UL VW-1 and CSA OFT flame-retardancy ratings. Temperature rating Minimum shrink temperature: 70°C 90°C – 30°C to 125°C Full recovery temperature: Continuous operating temperature: Specifications* ® ® Type Raychem UL CSA SWFR X4 SWFR X4 E35586 LR31929 *When ordering, always specify latest issue.
