Sumitube® Heat Shrink Tubing

Heat shrink tubing is used to insulate, protect, and organize electrical wiring and components across aerospace, electronics, automotive, and industrial applications. When heated, the tubing contracts to form a tight protective covering that helps improve electrical insulation, mechanical protection, and environmental resistance.

A.S.A.P. Technologies supplies Sumitube® heat shrink tubing, a product line developed by Sumitomo for electrical insulation, wire protection, and cable management. These materials are widely used in electronics, aerospace systems, and industrial manufacturing applications requiring reliable shrink performance and consistent shrink ratios.

Common Applications for Heat Shrink Tubing

Heat shrink tubing is widely used in applications requiring electrical insulation, environmental protection, and cable organization.

Typical uses include:

  • Electrical wire insulation and protection
  • Wire harness organization
  • Cable identification and bundling
  • Environmental protection for electrical connections
  • Mechanical protection for electronic assemblies

Flexible Polyolefins

Flexible polyolefin heat shrink tubing is commonly used for electrical insulation, wire harness protection, and cable organization. These materials provide reliable shrink performance while maintaining flexibility, making them suitable for electronics, industrial equipment, and general electrical applications.

Semi-Rigid Polyolefins

Semi-rigid polyolefin heat shrink tubing offers enhanced mechanical protection and structural stability compared with flexible tubing. These materials are often used in applications requiring stronger abrasion resistance and more durable insulation for electrical assemblies and cable management.

Special Purpose

Special purpose heat shrink tubing is designed for applications that require additional performance characteristics such as chemical resistance, high-temperature protection, or specialized insulation properties. These materials are commonly used in demanding industrial and electronic environments.
