EPDM renewable rubber high temperature performance, is widely used in outdoor wire and cable, doors and windows seals and other rubber products. However, due to the EPDM reclaimed rubber mostly solid black block, so the production of rubber products are mostly black. However, a single black EPDM rubber product can not meet user needs. For example, if all the black cable wires are used in the wiring process, it is difficult to distinguish between different areas and locations. In this case, once the wiring problem occurs, troubleshooting is difficult. Therefore, the production of light-colored color EPDM rubber products is imperative.
1, raw material selection
Black reclaimed rubber production of color EPDM rubber products is difficult to color, if a large number of high prices of titanium dioxide, it simply can not reduce the cost of raw materials, so the use of black EPDM reclaimed rubber production color rubber products simply not feasible . The use of EPDM reclaimed rubber production light-colored rubber products, the general use of light EPDM reclaimed rubber: light-colored EPDM reclaimed rubber and black EPDM renewable The same glue with excellent resistance to high temperature, anti-aging, high insulation performance characteristics for the production of light-colored EPDM rubber products not only to ensure product performance, but also can solve the problem of color matching difficulties.
2, pigment selection
Light-colored, color EPDM rubber raw material selected right, then have to re-emphasize the issue of color. The use of light-colored EPDM reclaimed rubber production color EPDM rubber products when the choice of color options is particularly important. Among them, many people go in a misunderstanding because of the pursuit of "whiter" and "shallower": add a lot of titanium dioxide. This EPDM renewable plastic products is pale down, but lost its brightness, making the product surface looks like "foggy", unknown customers will even think it is a white spray of rubber Therefore, it is best not to use titanium dioxide color in the color EPDM reclaimed rubber products, even in terms of cost.
About light-color EPDM reclaimed rubber products recipe method, the best than the use of masterbatch deployment; for some color in deep color EPDM rubber products can be directly added to the paint. In addition, silica, paraffin, rubber brightener, to improve the brightness of rubber products is very effective, if conditions can be properly added.
