The EPDM rubber compound is a raw material for the production of EPDM rubber products. Raw rubber or plastic compound rubber compounded according to formula and compounding agent by a rubber mixing machine is a blank of EPDM rubber products. Its quality is a key factor affecting the quality of EPDM rubber products.

In order to reduce the cost of raw materials, more and more EPDM rubber products enterprises began to use EPDM reclaimed rubber instead of EPDM rubber to produce rubber products. However, the performance of EPDM reclaimed rubber and EPDM rubber is different after all. Therefore, when using EPDM reclaimed rubber as the compounding rubber, it is necessary to properly adjust the compounding formula and take corresponding measures to ensure Product quality, to reduce raw material costs and ensure product quality. Then how to improve the rubber compound performance when EPDM recycled rubber is used as a rubber compound?

1. Add the appropriate unvulcanized EPDM rubber material for three purposes. First, it can reduce the Mooney viscosity of the compounded rubber, increase the fluidity, increase the plasticity, and be easy to process; second, it can prevent scorch to some extent. Phenomenon affects product performance; In addition, the addition of a certain amount of unvulcanized rubber compound to the EPDM rubber compound mixture can also improve the mixing, extrusion and rolling properties of the compound rubber.

2, EPDM rubber reclaimed rubber can be added to the right amount of vulcanized rubber to improve the performance of the rubber compound. On the one hand, it improves the tensile strength of the EPDM reclaimed rubber compound rubber and increases the tensile stress of the rubber compound. Increase the tear strength of rubber; on the other hand, adding vulcanizate to EPDM rubber can also reduce the permanent deformation of the compound; improve the flowability, water swelling and wear resistance of the rubber compound. The performance of the rubber products produced is comparable to that of the products produced by the original glue.

The quality of EPDM reclaimed rubber can be said to be related to the survival of rubber products manufacturers, improving the performance of EPDM reclaimed rubber compound rubber products is a joint research of rubber products manufacturers, then you have any good way to improve the EPDM Reclaimed rubber mix performance?
