Introducing the 328 Piece Heat Shrink Tubing Kit, the perfect solution for achieving neat and secure wire connections without the hassle of electrical tape. These heat shrink tubes are designed to shrink to 1/2 of their size when exposed to heat, providing a tight and professional-looking seal around wires. What's Included in the Kit: 120 pieces x 1.0mm (Yellow, Black, Red, Green) x 40mm 60 pieces x 2.0mm (Yellow, Black, Red, Blue) x 40mm 32 pieces x 3.0mm (Yellow, Black, Red, Green) x 40mm 32 pieces x 4.0mm (Yellow, Black, Red, Blue) x 40mm 32 pieces x 5.0mm (Yellow, Black, Red, Blue) x 40mm 32 pieces x 6.0mm (Yellow, Black, Red, Green) x 40mm 20 pieces x 8.0mm (Yellow, Black, Red, Blue) x 80mm 16 pieces x 10.0mm (Yellow, Black, Red, Green) x 80mm These heat shrink tubes are flame retardant, ensuring safety during use. They come in a flat format and can be easily cut with scissors or a sharp knife to fit your specific needs. Resistant to common fluids and solvents, these tubes effectively seal and protect wire connections. Made from high-quality Polyolefin material, the tubes have a shrinkage ratio of 2:1, meaning they will shrink to half of their original diameter when heated. The minimum shrinkage temperature is approximately 70 degrees Celsius, while the full shrinkage temperature reaches a maximum of 125 degrees Celsius. They can withstand a wide range of temperatures, from -55 to 125 degrees Celsius. The heat shrink tubes boast excellent dielectric strength of 15KV/mm and a tensile strength of 10.4 Mpa, making them reliable and durable for various applications, including RC hobbies and many other projects.
