- 2:1 Shrink Ratio: Our waterproof heat shrink tubing features a 2:1 shrink ratio, reducing to one-third of its original size when heat is applied. This ensures enhanced resistance to stretching and vibration, along with increased tensile strength. - Dual-Layer Design: Constructed with two layers, our heat shrink tubing provides reliable and durable protection. The inner layer is adhesive-lined, guaranteeing a waterproof and sealed connection. - Flame Retardant and Low Smoke: Made from polyolefin material, our heat shrink tubing is highly flame-resistant and produces minimal smoke. The meltable adhesive inner layer withstands temperatures from -67 to 125°C (-55 to 125°F). - User-Friendly Application: Easy to use, simply slide the tubing over the connection point and apply heat. In seconds, you'll achieve professional-grade insulated connections. Applications: 1. Electrical Insulation: Perfect for insulating electrical connections in automotive, marine, and household applications, ensuring safety and reliability. 2. Cable Protection: Ideal for bundling and protecting wires in harsh environments, preventing wear and tear from moisture and mechanical stress. 3. Sealing Connections: Use for waterproofing and sealing connections in outdoor equipment, providing long-lasting protection against the elements. With its robust features and practical applications, this heat shrink tubing is an essential tool for anyone needing secure and reliable insulation in their projects.
