2:1 Shrink Ratio, Semi-Rigid, Flame Retardant, Polyolefin Tubing
DUNBAR-1635S is meticulously designed to cater to a variety of wire strain-relief applications and terminations, including wire splices, and soldered or crimped connections. This heat shrinkable polyolefin tube offers exceptional durability, providing robust protection in challenging mechanical environments. Its high abrasion resistance ensures the integrity of delicate components, safeguarding them against physical damage that can occur during installation, maintenance, or operation.
Engineered with precision, DUNBAR-1635S is ideal for use in environments where wires and connections are subjected to mechanical stress and potential abrasion. The tube’s flexibility allows it to conform easily to irregular shapes and surfaces, ensuring a secure fit and consistent protection. This makes it particularly effective for securing and protecting wire splices, soldered joints, and crimped connections, preventing them from loosening or degrading over time.
In addition to its mechanical benefits, DUNBAR-1635S provides excellent thermal resistance, maintaining its protective qualities even under high temperatures. This makes it suitable for use in applications where heat exposure is a concern, such as in automotive, aerospace, and industrial settings. The tube’s flame retardant properties further enhance its safety profile, reducing the risk of fire and ensuring compliance with stringent safety standards.
DUNBAR-1635S is available in various sizes and can be easily cut to the desired length, offering versatility and ease of use. Its ability to shrink uniformly upon heating ensures a tight and reliable seal around wires and connections, enhancing both the mechanical and environmental protection. This feature is particularly beneficial in applications where moisture, dust, and other contaminants pose a threat to electrical integrity.
