SHRINK TUBING JAV-221

About Shrink Tubing JAV-221 - MIL-R-46846

Jaguar Industries' JAV-221 heat shrink tubing is an electrical grade polyolefin product engineered to meet rigorous MIL-R-46846 Type V, AMS-3587, UL, and CSA specifications for demanding military, aerospace, and high-reliability applications requiring maximum flexibility. Rated for continuous operation from -55°C to 135°C with exceptional capability to withstand elevated temperatures of 300°C for short periods, making it ideal for high-temperature wire harness assemblies and critical electronic installations. This is the most flexible heat shrinkable polyolefin tubing available from Jaguar Industries, specifically designed for jacketing of wire bundles where superior flexibility and conformability are essential. The 2:1 shrink ratio ensures excellent coverage and secure fit over various component sizes and cable assemblies. Available in fourteen sizes ranging from 3/64 inch to 4 inches, covering applications from delicate wire splices to large cable bundles and complex harness assemblies. Flame retardant versions available in black, white, and yellow as standard colors, with other colors and clear non-flame retardant versions available subject to minimum quantity requirements for custom applications. Wall thickness ranges from .016 inches to .055 inches nominal recovered thickness, providing robust insulation and mechanical protection while maintaining exceptional flexibility. Packaged in convenient 4-foot lengths and reels for production efficiency, with custom cut pieces available for specific applications requiring precise lengths. Outstanding physical properties include 2100 PSI tensile strength, exceptional 450% ultimate elongation providing superior flexibility and strain relief compared to standard polyolefin tubing, minimal ±5% longitudinal change for excellent dimensional stability, and 0.73x10³ PSI secant modulus. Specific gravity of 1.3 provides good balance between weight and performance. Superior thermal performance demonstrated through rigorous testing including heat aging showing 175% elongation retention after 168 hours at 175°C, heat shock resistance with no dripping or cracking after 4 hours at 250°C passing mandrel wrap test, and low temperature flexibility verified with no cracking after 4 hours at -55°C. Self-extinguishing flammability rating meets UL224 all-tubing flame test, ensuring fire safety in critical applications. Excellent electrical insulation properties with 800 V/mil dielectric strength and 10¹⁵ ohm-cm volume resistivity make JAV-221 ideal for high-voltage and high-reliability applications. Chemical resistance includes non-corrosive performance, good solvent resistance maintaining 750 PSI tensile strength and 400 V/mil dielectric strength after exposure, minimal water absorption of only 0.2%, and non-nutrient properties for fungus resistance in humid environments. Perfect for flexible wire harness jacketing, aircraft and aerospace wiring systems, military electronics requiring tight bending radius, automotive wiring harnesses, robotics and automation systems, medical device assemblies, industrial control systems requiring frequent flexing, telecommunications equipment, renewable energy installations, marine applications, mass transit systems, and any application requiring highly flexible heat shrink tubing with superior temperature resistance, excellent mechanical properties, and MIL-SPEC reliability. The combination of polyolefin material, maximum flexibility, wide temperature range, multiple color options, and comprehensive size availability makes JAV-221 the ideal choice for demanding applications requiring long-term reliability and performance in harsh environments where flexibility and conformability are critical requirements.
