Import Heat Shrink Tubing Kosoo K2 — Buy in Bulk from Supplier in China

Heat shrink tubing Kosoo K2 is an industrial‑grade electrical insulation product supplied by Guangzhou Kaiheng K & S Co., Ltd in China. The tubing is manufactured from polyolefin, a polymer known for flexibility and flame retardance. It offers a shrinkage ratio of 2:1, allowing the tube to reduce to half its original diameter when heated. The supplier lists a range of dimensions to suit applications from small electronics to heavy‑duty machinery.

Polyolefin heat‑shrink tubing generally operates between - 55 °C and +125 °C and is often rated V‑0 in the UL‑94 flame test. Standard wall thicknesses vary from 0.3 mm to 1.2 mm, with available outside diameters from 2 mm to 25 mm and lengths up to 100 m per coil. Colors such as black, red and transparent are typical for visual identification. These typical parameters align with the Kosoo K2 offering, providing reliable protection against abrasion, moisture and chemical exposure.

Typical buyers include electronics manufacturers, automotive assemblers and telecommunications contractors who need durable wire protection. Guangzhou Kaiheng K & S Co., Ltd states that MOQ is flexible and pricing is competitive for bulk orders, and the product complies with CE and ISO certifications. Importers should confirm the exact packaging format, lead time and Incoterms directly with the supplier. The tubing’s industrial‑grade construction makes it suitable for harsh environments where consistent insulation performance is required.

Guangzhou Kaiheng K & S Co., Ltd is located at No 148, Chang’an, Guangshan Highway, Guangzhou 510520, China.
