HTS-2000 Standard Heat Shrink Tube, 2:1 Ratio, 2.0mm–12.7mm ID, Polyolefin, UL224 Certified

HTS-2000 Standard Heat Shrink Tube, 2:1 Ratio, 2.0mm–12.7mm ID, Polyolefin, UL224 Certified

Product Overview

The HTS-2000 Standard Heat Shrink Tube is a high-performance, UL224 certified polyolefin shrink tube engineered for reliable electrical insulation, environmental protection, and mechanical strain relief in demanding industrial and commercial applications. With its precise 2:1 shrink ratio and versatile inner diameter range (2.0 mm to 12.7 mm), this heat shrink tube delivers consistent, uniform recovery across diverse cable and component sizes—making it an ideal choice for global OEMs, contract manufacturers, and MRO distributors seeking certified, field-proven 2:1 heat shrink tubing.

Manufactured from cross-linked polyolefin, the HTS-2000 offers excellent flame retardancy (UL VW-1 rated), superior abrasion resistance, and broad chemical compatibility. Its low shrink temperature (starting at ~85°C) ensures safe use on heat-sensitive components without compromising full recovery or sealing integrity. As a UL224 certified heat shrink tube, it meets stringent North American safety and performance standards—providing B2B buyers with documented compliance for audits, certifications, and regulatory submissions.

Key Features

UL224 certified and VW-1 flame rated for electrical safety compliance
Precise 2:1 shrink ratio ensures tight, conformal fit over irregular shapes and connectors
