Import Boxed Heat Shrinkable Tube — Buy in wholesale FOB from Supplier in China

Huawo Heat Shrinkable Material Co., Ltd. supplies boxed heat shrinkable tube manufactured from cross-linked polyolefin (XLPO), a material chosen for its electrical insulation and mechanical durability properties. The tubes exhibit a typical 3:1 shrink ratio, expanding from a supplied diameter to one-third of that size upon controlled heating. Standard operating temperatures span from -55°C to 135°C, sufficient for most wire harness and cable termination environments. The boxed format targets both retail distribution and organised bulk procurement, with carton packaging designed for clear customs identification.

The XLPO construction provides resistance to abrasion, common solvents, and moisture ingress when specified in adhesive-lined dual-wall configurations. Standard colour options include black, red, blue, yellow, and green, allowing phase identification and aesthetic matching in electrical assemblies. The material cross-linking process ensures the tube retains its shrunken state without relaxation after thermal cycling, a typical performance characteristic of properly cured polyolefin compounds. Wall thickness after full shrinkage varies by original tube size, with thinner walls suited to tight-space electronics and heavier walls for mechanical protection in automotive looms.

Primary applications encompass wire connection insulation, solder joint protection, wire end sealing, capacitor insulation, wire marking, antenna sheathing, and corrosion protection for metal tubes and rods. Buyers span automotive wiring harness manufacturers, electronics assembly contractors, telecommunications infrastructure installers, and maintenance operations in industrial plants. The supplier's location in Huizhou, Guangdong Province, places it within China's Pearl River Delta electronics manufacturing corridor. Importers should confirm shrink ratio tolerance, adhesive lining availability, and specific colour minimum order quantities directly with Huawo, as these parameters determine unit economics and lead times.

Huawo Heat Shrinkable Material Co., Ltd. maintains its registered address at Building A, TCL Yunshan Industrial Zone, No. 21, E, in Huizhou, Guangdong Province, 516000, China. The company's placement within the Pearl River Delta positions it near major electronics component markets and Shenzhen's shipping infrastructure. The supplier holds a harbor trust tier classification on the marketplace, and its response rate is recorded at 0.00% with zero average response hours, indicating no historical buyer engagement data is available through the platform. No verification of factory audit, export licence, or ISO certification status is displayed.

The listing focuses exclusively on boxed heat shrinkable tube products without indicating manufacturing capacity, year of establishment, employee count, or key clientele. The product description references UL and RoHS compliance, though specific certificate numbers or accredited body details are not provided. Buyers should request copies of current compliance documentation and confirm whether Huawo operates as a manufacturer or trading intermediary. The absence of response history suggests direct communication channels, rather than platform messaging, may prove more reliable for quotation and sample requests.
