Cold Shrink Tubing

Why Use Cold Shrink Tubing?

While heat shrink tubing is the most common choice in cable splicing and connector coverage, there are often situations where it is  impractical, unsafe, or simply impossible to use heat shrink. When applying  shrink tube in volatile environments where the introduction of heat may be  dangerous, cold shrink tubing offers all the benefits of heat shrink tubing but  without the need to introduce heat. This allows our clients seal and cover  cables, connectors and pipes in a safe manner. A perfect application for cold shrink tubing would be covering  high-voltage cables for mining equipment.   Adding heat or a flame to this type of  environment could lead to the ignition of an unknown flammable gas. Using cold  shrink in this application can save lives. Cold shrink tubing can also be used for covering and insulating underwater oil  pipes. Our cold shrink sealing kits ,EDL Series, can be used for sealing of  coax cables with Type N or 7/16 DIN  connectors. Gamma Electronics manufactures two types of cold shrink that may  be used for these tough applications.


Silicone Cold Shrink

Silicone is a semi-organic elastomer with outstanding resistance  to extreme temperatures with corresponding resistance to compression set and  retention of flexibility. Silicone elastomers provide excellent resistance to  ozone, oxygen and moisture. Low physical strength and abrasion resistance combined  with high friction properties limit silicone to static seal applications.  Silicone utilizes a flexible sioxane backbone rather than a carbon backbone  like many other elastomers and has a very low glass transition temperatures.  Silicone cold shrink has extreme temperature properties and excellent  compression set resistance. It is also is very clean, has low odor and high  flexibility. For a view of our specifications on our  silicone cold shrink please click the link below.

EPDM Cold  Shrink

Ethylene-propylene  is prepared from ethylene, propylene (EPM) and a third monomer (EPDM).  EPDM  has good resistance to mild acids, detergents, alkalis, silicone oils and  greases, ketones, and alcohols. It is not recommended for applications with  petroleum oils, mineral oil, di-ester lubricants, or fuel or fuel exposure.

Ethylene Propylene has gained wide industry  acceptance for its excellent ozone and chemical resistance properties. It is also  compatibility with many polar fluids that adversely affect other elastomers.

Our EPDM compound is great for higher temperature  exposure and will has improved compression set performance. This allows for  rugged outdoor exposure over long periods of time.
