The Cembre 2811235 is a premium polyolefin heat shrink tubing designed to provide reliable electrical insulation, cable identification and long-lasting mechanical protection. Manufactured by Cembre, this TERMOBLOCK heat shrink sleeve is ideal for industrial wiring, control panels, automation systems and OEM electrical installations requiring dependable cable management.
Featuring a 2:1 shrink ratio, the tubing shrinks securely around cables and electrical connections, providing excellent resistance to abrasion, moisture, chemicals and environmental contaminants. Its halogen-free, flame-retardant polyolefin construction delivers exceptional durability while remaining flexible for fast and professional installation.
With an internal diameter of 1.5 mm before shrinking, approximately 0.65 mm after shrinking, and supplied on a 20 m coil, the brown Cembre 2811235 is ideal for cable insulation, wire marking and colour-coded identification in demanding industrial electrical applications.
Heat shrink tubing provides a durable insulating barrier around cables and electrical terminations while improving resistance to vibration, abrasion and environmental exposure. Once heated, the tubing contracts tightly around the cable to create a neat, professional finish while extending the service life of electrical installations.
Cembre TERMOBLOCK tubing is trusted by electricians, panel builders and OEM manufacturers for dependable cable insulation, mechanical protection and professional cable identification in demanding industrial environments.
