    3M Cold Shrink products contain elastomeric bonds, giving them elasticity similar to rubber bands. When stretched and then allowed to shrink onto a cable, they exert a strong inward force that produces a constant squeezing effect on the cable – providing excellent electrical performance, and superior environmental sealing compared to heat shrink cable accessories.

     

    It’s a dramatic difference you can immediately see in this demonstration video!
