Application of reclaimed rubber in EPDM sealing strip


EPDM sealing stripSmall density, high elasticity, sealing effect, excellent cushioning performance,EPDM sealing stripCommonly used raw materials are EPDM rubber, nitrile rubber, chloroprene rubber and butyl rubber, but the price of raw rubber on the market has been high. It is usually manufactured by continuous extrusion and vulcanization of foam rubber for sealing in various occasions. It is a big challenge for manufacturers.; Recycled rubber reprocessed from recycled rubber products is much cheaper than raw rubber and is usedEPDM sealing stripThe production of, then, the following together to understand the reclaimed rubber inEPDM sealing stripapplication in it!

1. Tri-propylene reclaimed rubber inEPDM sealing stripapplication in

Triacrylic reclaimed rubber has excellent high and low temperature resistance and anti-aging properties. Among them, black triacrylic reclaimed rubber can be combined with triacrylic rubber to prepare black sponge sealing strips, mostly using carbon black as reinforcing agent, salt bath vulcanization, hot air vulcanization or microwave-Hot air vulcanization; it can replace some sponge sealing strips produced by tri-acrylic HYL26Y11Y1J-SXC.Light color EPDM reclaimed rubber can be combined with EPDM rubber to prepare light colorEPDM sealing stripThe formula generally uses white carbon black reinforcement, titanium dioxide color.


2. Nitrile rubber reclaimed rubber in oil resistanceEPDM sealing stripapplication in

Regenerated nitrile rubber is characterized by good oil resistance, used in a variety of oil media is not easy to swell, can maintain a good sealing effect for a long time..Among them, the nitrile rubber open-hole sponge sealing strip mostly uses foaming agent.H and foaming agent TSH, closed-cell preparation from nitrile rubber reclaimed rubberEPDM sealing stripMore appropriate choice of foaming agentAc. Reclaimed rubber can be used in conjunction with nitrile rubber to prepare open-cell sponge sealing strips, or it can be used in nitrile rubber in an appropriate proportion to prepare closed-cellEPDM sealing strip.

3. Butyl reclaimed rubber inEPDM sealing stripapplication in

Butyl rubber has good air tightness, heat resistance, aging resistance and chemical corrosion resistance, and the reinforcing filling system uses carbon black and heavy calcium..Foaming agent can be selected in the foaming systemThe combination of OBSH and Vaseline as foaming agent.Production using reclaimed rubberEPDM sealing stripIt can be combined with butyl rubber to prepare low-density closed cells.EPDM sealing strip.Generally choose peroxide vulcanization, in order to ensure the foam sealant uniform foaming, smooth extrusion, rubber products manufacturersToChoose high purity, no impurities of reclaimed rubber products.

Commercially available reclaimed rubber is roughly divided into latex reclaimed rubber, tire reclaimed rubber, butyl reclaimed rubber, nitrile rubber reclaimed rubber and EPDM reclaimed rubber according to the types of raw materials. Different types of reclaimed rubber production and production of rubber products replace the corresponding In theory, EPDM reclaimed rubber and nitrile rubber-Butyl reclaimed rubber can be incorporated into the production of sponge sealing strips in a certain proportion. The type and dosage of reclaimed rubber used in foaming sealing strips are different under different use conditions, and the production process is quite different.
