EPDM rubber seal Material can be divided into several categories

EPDM sealing strip Material can be divided into two categories: dense foam strips and strips, dense seal hardness generally between 65 degrees -90 degrees; foam seal hardness between 15 degrees to 35 degrees, the product is soft, back flexibility for a variety of seal block, gaskets, etc.

Vulcanized EPDM sealing strip according to the method can be divided into:

      (1) non-continuous vulcanization (the extruded strip after cutting a certain length, into the autoclave curing, semi-finished products will be extruded into strips sulfide model);

  2) continuous vulcanization (microwave continuous vulcanization method, continuous vulcanization bath, hot air continuous vulcanization method in several ways). A. microwave continuous vulcanization composite seal: Microwave curing technology is applied and been widely promoted production technology abroad after the 1970s energy crisis. Microwave continuous vulcanization technology can not only produce a metal core, dense rubber with a variety of materials extruded styrofoam, and, in energy conservation, improve efficiency and other aspects of continuous vulcanization method is superior than the other devices. This technology has been recognized as the world best process for the production of extruded products. Microwave heating is characterized by heat generated within the object being heated directly, rather than as conventional as input from the outside, so that the heat is not only fast, but also distribution, help to improve product quality and shorten the time spent heating. B. Salt continuous vulcanization Seal: using containing nitrite curing salt bath salt bath system, larger environmental pollution, has gradually been eliminated. C. hot air vulcanization Seal: hot air vulcanization has now developed into a strong wind sulfide, which uses high-temperature, high-speed hot air vulcanization (Tmax: 450 ° C and Vmax: 60m / s) can also be reached flame pretreatment effect, and security is greatly improved.
