Heat Shrink Tubing
Single Wall
Single Wall cross-linked polyolefin heat shrink products, such as DERAY-I, are used for electrical insulation and strain relief in an endless number of industries and applications. DERAY-I is widely used since it is RoHS compliant and meets the performance requirements of UL and Military.
Although DERAY-I is a prime candidate for almost all applications, some situations demand special requirements for wall thickness, flammability rating or shrink ratio and the following chart will help with selection.

Dual Wall
Dual wall heat shrink tubing is a cross-linked polyolefin tube that is extruded with an inner layer of adhesive. Upon recovery of dual wall heat shrink, the inner layer of adhesive will melt and flow. In the dual wall or adhesive lined heat shrink category, CPA 300 stands out as a product that is well suited for many different applications. The product meets UL 224 and SAE-AMS-DTL-23053/4 standards with the flammability rating applying to the total tube (many products are rated as jacket only). It is also ideal for connector and terminal applications since the CPA adhesive is the strongest in the field for bonding to copper, steel, and polyethylene.The chart below highlights some of the other options available for dual wall products including: shrink ratio, rigidity, and operating temperature.

Medium and Heavy Wall
Medium and heavy wall heat shrink tubing is used in a variety of applications to seal and protect wire and cable connections. For general purpose sealing and cable re-jacketing applications, CFM, a medium wall heat shrinkable tubing is available in expanded tube diameters up to 9.0 inches. Combined with the superior bond of the hot melt adhesive CFM provides a watertight seal to cover the largest application range offered in the industry.

Specialty Non-Polyolefin Heat Shrink Tubing
Non-polyolefin heat shrinkable products are made from base materials such as VitonŽ, Polyvinylidene Fluoride (PVDF), and Neoprene to provide improved properties for: fluid resistance high temperatures abrasion resistance For example, DERAY KY 175 is a PVDF heat shrink with a 2:1 shrink ratio with a maximum operating temperature of 175°C. Combined with its exceptional fluid and abrasion resistance, it is a good choice for high temperature automotive components.

Heat Shrink Tubing for Automotive Applications
Single wall and dual wall heat shrink are most commonly applied in automotive but DSG-Canusa has many specialized medium/heavy wall and non-polyolefin heat shrink products for demanding applications. DSG-Canusa works closely with global OEMs and Tier 1 suppliers to select and test the most cost effective heat shrink products for more complex applications. Our heat shrink products are approved and vehicle tested on all major car and truck lines. To provide detailed support, DSG-Canusa has sales and engineering support close to the major automotive design and manufacturing clusters in North American and Europe and Asia. For efficient, repeatable application of heat shrink, we design and develop our own DERAY automotive shrink ovens. Models are available for high volume splice sealing, on-board application and bench top processing.
