Secondary vulcanization is also called post vulcanization or secondary vulcanization,

Refers to the rubber products reach a certain degree of vulcanization, remove the heat source to continue heating vulcanization process. In a broad sense, rubber products vulcanization to a certain extent, even if not heated, it can still be under the action of waste heat, or in the process of product storage, continue to deepen the vulcanization process, or under the dynamic action of continued cross-linking phenomenon. Of course, it also includes the process of continuing to heat the second stage vulcanization;

The purpose of secondary vulcanization is to further cross-link rubber products and improve the mechanical properties and compression permanent deformation properties of rubber products.

The method of secondary vulcanization is oven hot air vulcanization or the use of canister hot air secondary vulcanization;

At present, many rubber seals or rubber products production units use secondary vulcanization technology to make rubber sealing products, technology is also changing with The Times, constantly updated, constantly optimized!
