Import Heat Shrinkable Dual-Wall Tube — Buy in Bulk from Supplier in United States

The Heat Shrinkable Dual-Wall Tube offered by Huawoer is a two‑layer shrink tubing where the outer wall is a cross‑linked polyolefin and the inner wall contains a hot‑melt adhesive. The product provides a 3:1 shrinkage ratio, starts shrinking at 70 °C and reaches full shrink at 125 °C. Working temperature range is - 40 °C to 125 °C and the adhesive melt point lies between 70 °C and 100 °C. Standard colour is black with ten additional colours available on request. The tube’s medium wall thickness balances mechanical protection with flexibility.

The outer layer’s cross‑linked polyolefin gives insulation, corrosion resistance and wear resistance, while the inner adhesive layer bonds to plastic, rubber and metal surfaces. Typical industry variants include flame‑retardant grades and high‑temperature formulations, which are offered as part of Huawoer’s product line. Standard industry practice for dual‑wall heat‑shrink tubing calls for a dielectric strength of about 2000 V and tensile strength around 30 MPa, values that the material can meet. The adhesive is formulated to provide waterproof sealing and high adhesion after shrinkage.

These tubes are commonly used for automotive wiring, aerospace cable bundles and industrial equipment where moisture protection and mechanical shielding are required. OEMs, contract manufacturers and system integrators source them for pipeline protection, cable management and environmental sealing. Huawoer states that it can supply custom lengths, colours and packaging, and accepts sample orders; payment and delivery terms are negotiable but must be confirmed directly with the supplier.
