4:1 Shrink Ratio, Semi-Rigid, Dual-Wall Polyolefin Tubing
DUNBAR-4635WS is a robust, semi-rigid, high shrink ratio, flame-retardant, heat-resistant, and mechanically tough heat-shrinkable polyolefin tubing with an advanced adhesive lining that flows when heated. This specialized tubing is engineered to provide superior sealing and protection across a broad spectrum of demanding electrical applications.
Key Features and Benefits:
- High Shrink Ratio:
- DUNBAR-4635WS boasts a high shrink ratio, enabling it to accommodate a wide range of component sizes and shapes. This versatility ensures a snug and secure fit around irregular and complex geometries, making it suitable for various electrical and electronic applications.
- Flame Retardancy and Heat Resistance:
- With flame-retardant properties, this tubing meets stringent safety standards, reducing the risk of fire hazards in critical applications. Its heat-resistant nature ensures reliable performance even in high-temperature environments, maintaining its protective capabilities under demanding conditions.
- Mechanical Toughness:
- Constructed from a mechanically tough polyolefin material, DUNBAR-4635WS offers exceptional durability. It provides robust protection against physical damage, abrasion, and environmental stress, ensuring long-term reliability and integrity of the insulated components.
- Adhesive Lining:
- The tubing is lined with a high-performance adhesive that flows and bonds upon heating. This adhesive layer ensures a watertight and secure seal, effectively protecting against moisture, dust, and other contaminants. The adhesive also enhances mechanical strength, further stabilizing connections and splices.
- Versatile Application:
- DUNBAR-4635WS is designed to seal and protect a wide variety of electrical applications, including:
- Wire Splices: Ensuring secure and insulated connections.
- Breakouts: Providing reliable sealing at cable breakouts.
- Connectors-to-Cable Transitions: Offering robust protection and strain relief for connectors interfacing with cables.
- Ease of Installation:
- The tubing’s high shrink ratio and adhesive lining simplify installation, providing a quick and effective method for sealing and protecting electrical components. When heated, the tubing shrinks uniformly, and the adhesive flows to fill gaps, creating a reliable and durable barrier against environmental factors.
Applications:
- Automotive Industry: Ideal for protecting wire splices and connectors in automotive wiring harnesses, ensuring durability and safety.
- Aerospace and Defense: Suitable for high-reliability applications where flame retardancy and mechanical toughness are critical.
- Industrial Equipment: Used in machinery and equipment to safeguard electrical connections from harsh environmental conditions.
- Telecommunications: Protects splices and connectors in communication networks, ensuring long-term performance and reliability.
DUNBAR-4635WS represents an optimal solution for engineers seeking a high-performance, semi-rigid, heat-shrinkable tubing that offers outstanding flame retardancy, heat resistance, and mechanical toughness. Its advanced adhesive lining and versatile application make it an indispensable component in ensuring the safety, reliability, and longevity of electrical systems across various industries.
