    New Energy Heat Shrinkable Tube

    New energy heat shrinkable tubes are protective sleeves used in electric vehicles, renewable energy systems, and battery packs. They offer insulation and protection for wires, cables, and battery terminals. These tubes shrink when heated, providing a tight seal and excellent electrical insulation. They're resistant to heat, chemicals, and environmental factors, ensuring reliable and safe electrical connections in modern energy applications.

  • PTFE TUBE

    PTFE TUBE

    PTFE tube is a tubing made from polytetrafluoroethylene, renowned for its chemical resistance, high-temperature tolerance, and low friction properties. It finds extensive use across industries such as chemical processing, automotive, aerospace, and medical due to its versatility and reliability in fluid transfer, insulation, and electrical applications.

  • Dual Wall Heat Shrink Tube

    Dual Wall Heat Shrink Tube

    Dual wall heat shrink tube is a double-wall heat shrink tube with an inner layer made of hot melt adhesive and an outer layer made of heat shrink material. Through heating, the inner layer of hot melt glue forms a seal at the connection part, and the outer layer of heat shrinkable material tightly wraps the connection part to provide additional protection and insulation. Dual wall heat shrink tube is commonly used in electrical, communications and automotive fields for waterproofing, moisture-proofing, insulation and protection of connection parts.

  • Busbar Insulation Sleeves

    Busbar Insulation Sleeves

    Bus-bar shrinkable protection tube is a heat shrinkable tube used to protect electrical bus bars. It is usually composed of a double-wall structure and contains hot melt adhesive. By heating, it tightly covers the busbar and forms a sealed protective layer to prevent electrical equipment from moisture, chemicals or mechanical damage.

  • Pattern Heat Shrink Tube

    Pattern Heat Shrink Tube

    Patterned anti-skid heat shrinkable tube is made of radiation-modified polymeric warp-knitted material. Its function is anti-skid decoration. It is widely used in high-end fishing gear, sports equipment, fitness equipment, daily necessities, various hand tools, and kitchen appliance handles.

  • Silicone Rubber Heat Shrinkable Tube

    Silicone Rubber Heat Shrinkable Tube

    Silicone rubber heat shrinkable tube is a heat shrinkable tube made of silicone rubber material. This pipe offers high temperature resistance, flexibility and excellent insulating properties. Under the influence of heat, it shrinks to a portion of its original diameter, tightly wrapping the surface of the covered component to form a durable protective layer.

  • Fluororubber Heat Shrinkable Tube

    Fluororubber Heat Shrinkable Tube

    Fluororubber heat shrinkable tube is made of fluororubber and polymer elastomer through radiation modification and can be used at high temperatures for a long time. It is resistant to diesel, aviation fuel and high-temperature fluids. It can be used for the protection of military vehicles, high-speed trains, ship equipment or commercial cable terminals, separation joints, etc.

  • PVDF Heat Shrinkable Tubing

    PVDF Heat Shrinkable Tubing

    Pvdf heat shrinkable tubing uses modified polyvinylidene fluoride (PVDF) and meets the requirements of SAE-AMS-DTL-23053/18 military standards. The special formula makes it transparent and flame retardant. Can be used at temperatures up to for extended periods of time and is wear and cut resistant and has good corrosion resistance to most oils and chemicals. It is widely used in the protection of welding points, terminal blocks and connecting wires due to high temperatures, industrial fuels, solvents and chemical reagents.

  • Nylon Braided Hose

    Nylon Braided Hose

    Nylon braided hose is made of polyester monofilament, nylon monofilament and other monofilaments, and has the characteristics of high strength, wear resistance and corrosion resistance. It has good bending, resilience, wear resistance, stretchability and breathability, so it can be widely used in the sheathing and protection of wires.

  • PVC Pipe

    PVC Pipe

    PVC pipe is a common plastic pipe made of polyvinyl chloride (PVC) resin. It has many advantages such as corrosion resistance, chemical resistance, lightweight, easy installation and low cost. PVC pipes are widely used in construction, drainage, water supply, sewage, ventilation, power line pipes and agricultural irrigation and other fields.

  • Corrugated Pipe

    Corrugated Pipe

    Corrugated Pipe is a pipe with a wavy appearance, usually made of plastic, PP, and nylon. Its features include lightness, flexibility, pressure resistance and corrosion resistance, and is suitable for drainage systems, exhaust systems, cable protection and other fields. The corrugated pipe's corrugated structure gives it high stiffness and pressure resistance, while maintaining a low weight for easy handling and installation. They are widely used in construction, engineering, agriculture and other fields, and are an economical and practical pipe material.
