Import Big Diameter Pe Materials Heat Shrink Tube — Buy in wholesale FOB from Supplier in China

This big diameter PE materials heat shrink tube from Shenzhen Sunbow Insulation Materials Mfg. Co., Ltd in Shenzhen, Guangdong, is manufactured from polyethylene formulated for thermal recovery and cable insulation protection. The product accommodates a range of conductor bundle diameters through its expanded and recovered states, with a recovered wall thickness and longitudinal shrink ratio typical of medium-wall industrial heat shrink tubing. It is rated for continuous operating temperatures up to 125°C, with resistance to chemicals, UV radiation and flame propagation for outdoor and harsh environment applications.

The polyethylene base material provides standard electrical insulation properties including dielectric strength and volume resistivity, while additives confer thermal stability and flame retardance. The big diameter range targets medium-to-large cable harnesses, busbar insulation and pipe corrosion protection where standard small-diameter tubing is insufficient. For heavy machinery, telecommunications infrastructure and automotive electrical systems, the combination of large recovered diameter, flexibility before shrinking and rigid protection after recovery addresses mechanical abrasion and environmental sealing requirements typical of these sectors.

Buyers in construction, automotive OEM supply, telecom network installation and power distribution will assess this product against specifications for shrink ratio, tensile strength after recovery, and compliance with relevant insulation material standards. The listing mentions ISO and SGS certifications without specifying standards or scope numbers, which requires direct verification. The supplier's harbor trust tier and zero recorded response rate mean buyers should allow additional lead time for technical data sheet provision and sample qualification before committing to volume orders.

Shenzhen Sunbow Insulation Materials Mfg. Co., Ltd is located at No 8, 2nd Industrial Zone, Xiacun Community, Gongming Town, Guangming District, Shenzhen, Guangdong Province, 518106, China. The company holds a harbor trust tier on the platform. The response rate is recorded at 0.00% with zero average response hours, indicating no tracked communication history through the platform channel. The address places the supplier in Shenzhen's northwestern industrial corridor, within the Pearl River Delta manufacturing cluster with access to Shenzhen Port and Yantian Container Terminal for export logistics.

The supplier profile does not state establishment year, factory floor area, employee count, annual turnover, or specific export markets served. The listing references ISO and SGS certifications without certificate numbers, scopes or dates, which buyers must verify directly. No specific product standards such as UL, CSA, or RoHS compliance are confirmed in the available data. The company name indicates specialisation in insulation materials manufacturing, but actual production capacity, in-house compounding capability, and OEM/ODM service scope require direct enquiry and potential factory audit before reliance.
