Raychem BSTS/BSTS-FR Heat Shrink Tubing: Robust Protection for Electrical Connections

The Raychem BSTS/BSTS-FR heat shrink tubing from TE Connectivity is a durable solution designed to effectively insulate and protect electrical connections. Made from a robust polymer that is resistant to moisture, mold, and weathering, this heat shrink tubing offers excellent electrical properties. As a result, the BSTS/BSTS-FR heat shrink tubing is ideal for applications where insulation, abrasion resistance, and strain relief are crucial. Whether for industrial installations or electronic equipment, this heat shrink tubing guarantees reliability and a long lifespan.

Diverse Applications of BSTS Heat Shrink Tubing

The BSTS heat shrink tubing is not only effective for insulation but also provides a solid seal against moisture and other external factors, especially when used in combination with sealing tape such as S-1305 for flame-retardant applications or S-1278 for non-flame-retardant applications. This allows for the creation of a waterproof system in non-pressure applications. With its versatility, the Raychem BSTS/BSTS-FR heat shrink tubing is an indispensable choice for any sector reliant on durable and reliable electrical connections.
