EPDM reclaimed rubber is a kind of recycled rubber that is recycled and reprocessed from waste ethylene propylene rubber, which realizes the recycling of resources. EPDM reclaimed rubber retains the basic performance characteristics of EPDM rubber, with excellent high and low temperature resistance and aging resistance. It is often used in the manufacture of rubber caps and gaskets. Rubber caps and gaskets produced with EPDM reclaimed rubber have the following advantages and features.
First of all, the rubber caps and gaskets made of EPDM reclaimed rubber have good aging resistance. EPDM rubber has good weather resistance and aging resistance, and the EPDM reclaimed rubber processed from waste EPDM rubber products can maintain these properties unchanged after proper treatment and additive blending. Therefore, the rubber caps and gaskets produced by EPDM reclaimed rubber can be used for a long time in various harsh environments, are not easy to age and break, and have a long service life.
Secondly, the rubber caps and gaskets produced by EPDM reclaimed rubber have lower costs. Compared with the rubber caps and gaskets produced by EPDM rubber, the production cost of EPDM reclaimed rubber products is lower, and the production cost can be reduced by about 20-35%. This is a very considerable cost saving for rubber products manufacturers.
When designing the rubber cap and rubber gasket formula produced by EPDM reclaimed rubber, it is necessary to reasonably design the vulcanization system, especially the selection of vulcanizing agent. The selection of vulcanizing agent should be determined according to the characteristics of EPDM reclaimed rubber and the requirements of the product to ensure the coordination of vulcanization effect and product performance. In addition, the vulcanization temperature and vulcanization time in the vulcanization process also need to be reasonably controlled to avoid the problem of over-vulcanization or under-vulcanization.
Mixing is one of the important processes in the production of rubber products. EPDM rubber caps and EPDM reclaimed rubber gaskets need to be fully mixed with other additives to ensure uniform dispersion and good compatibility with other components. In addition, parameters such as temperature, time and shear force in the rubber compounding process also need to be reasonably controlled to ensure the quality and performance of the rubber compound.
The rubber caps and gaskets produced by EPDM reclaimed rubber have the advantages of anti-aging, long service life and low cost. There are a few key factors that need to be paid attention to during vulcanization formulations and compounding to ensure the quality and performance of reclaimed rubber. Through the rational application of EPDM reclaimed rubber, the recycling of resources and environmental protection can be realized, and at the same time, the production cost can be reduced, and the economic and environmental benefits can be brought to the rubber products industry.
