The use of latex reclaimed rubber to produce rubber products can not only solve the problem of high and unstable raw material prices, but also ensure that the use performance of rubber products is not affected and is welcomed by natural rubber product companies. However, when rubber products are completely produced using latex reclaimed rubber, cracking may occur for a period of time. At this time, the first reaction of rubber products companies was “a problem with latex reclaimed rubber.” Is that really the case? Come and look at the engineers of Hongyun to see the cause of cracks in latex reclaimed rubber products and tips to prevent cracking!

In fact, cracking of latex reclaimed rubber products does not have much to do with the quality of reclaimed rubber products (doesn't rule out the inferior quality of latex reclaimed rubber causing product quality problems, so the choice of latex reclaimed rubber is very important. The quality of latex reclaimed rubber produced by regular manufacturers is more Safeguarding, do not "greatly greedy for a small loss." Mostly caused by unreasonable formulas. If rubber compound is used to produce rubber products completely, if the formulation is not adjusted properly, cracking will occur after a certain period of time. Some cracked latex rubber products generally appear in three months to six months. This problem can be easily solved by adjusting the recipe.

The cracking phenomenon in rubber products is mainly caused by ozone, so just add an appropriate amount of anti-ozone antioxidants, for example, the amount of 4020, AW, RD and DTPD can be increased by an appropriate amount, and the amount of 3100 used can also be reduced. The conditional product companies may also consider adding some natural rubbers to use as appropriate. Antioxidant 4020 is a p-phenylenediamine rubber anti-aging agent. It has a white powder and has remarkable anti-oxidation and anti-ozone effects. It can also inhibit the effects of flex cracking and harmful metals such as copper and manganese. The performance is similar to that of 4010NA but it is irritant. Smaller, more water soluble.

In addition, the technical personnel of Hongyun Reclaimed Rubber Factory remind you that the use of reclaimed rubber can reduce the cost, but for some rubber products with stringent product performance requirements, it is better not to use latex reclaimed rubber to produce it completely. Although the raw material cost will be reduced in the earlier period, In the later period, various problems may occur, such as the aging of the rubber product system, the shortened life span, and even the loss of the market in serious cases. This is not worth the candle. Take latex reclaimed rubber as an example, we advocate the use of latex reclaimed rubber in combination with natural rubber. When performance permits, it is best to use reclaimed rubber and natural rubber as auxiliary. This can not only reduce the cost of raw materials, but also guarantee rubber products. Use the same performance, longer life.
