Wholesale cold shrink tube is currently divided into silicone cold shrink tube and EPDM cold shrink tube according to the main raw materials for manufacturing, which are made of silicone rubber and EPDM rubber respectively. The principle of shrinkage is the same, so the following is an example of a silicone cold shrink tube.

Cheapest cold shrink tube Wholesale Price

Wholesale cold shrink tube silicone rubber raw rubber after kneading and vulcanization, the original silicone macromolecular structure will undergo cross-linking reaction to form a network structure, thereby increasing the connection strength and elasticity between the silicone molecules, the elasticity is through the intermolecular Configuration changes, as well as molecular bond length changes are achieved.

Unvulcanized raw rubber is easy to tear, and can be torn gently by hand, just like tearing dough, but after vulcanization, the silicone becomes elastic, like rubber. That is to say, after the vulcanization process, the silicone tube we extrude can be released and deformed under the action of external force. Due to the deformation and internal stress, a certain degree of retraction occurs, that is, resilience, which is the shrinkage principle of Wholesale cold shrink tube.

It should be noted that this principle is a bit like Wholesale cold shrink tube, but the difference between Wholesale cold shrink tube and heat shrink tube is that the molecules of the heat shrink tube are frozen at room temperature and need high temperature activation, so heating is required, so it is called heat shrink. The cold shrink tube does not need to be heated, so it is called cold shrink in the industry, which is a later product that is different from heat shrink.
