The wiper strip is an important accessory in the car and is of great significance for safe driving. Because the wiper strip is exposed to the air for a long time, it is necessary to apply various climatic conditions, especially in rain and snow weather, so it is necessary to use excellent EPDM rubber with high and low temperature resistance and aging resistance. EPDM reclaimed rubber is a low-cost substitute to high-priced EPDM raw rubber, which can replace EPDM rubber to produce various rubber products and reduce raw material costs. So can EPDM reclaimed rubber be used in wiper strip processing, and what issues should be paid attention to?
1.Choic of EPDM recycled rubber for wiper strips
EPDM rubber retains the basic molecular structure and performance characteristics of EPDM rubber, and has good compatibility with EPDM rubber. In theory, it can directly replace EPDM rubber to produce automotive wiper strips. When using EPDM reclaimed rubber to reduce the production cost of wiper strips, rubber product manufacturers can choose the products that are closest to the various specifications of wiper strips according to actual needs. In this way, the amount of EPDM reclaimed rubber can be increased as much as possible.
It should be noted that automotive rubber products have strict environmental protection requirements. Therefore, when using EPDM reclaimed rubber to reduce the production cost of wiper strips, rubber product manufacturers choose environmentally friendly EPDM reclaimed rubber and tasteless EPDM that pass the relevant testing standards. Recycled rubber, the effect is better.
2. Usage and dosage of EPDM reclaimed rubber in wiper strips
The main role of EPDM reclaimed rubber in the production of wiper strips is to reduce the cost of raw materials. From the perspective of cost, the more the amount of reclaimed rubber, the better. However, because the mechanical strength of EPDM reclaimed rubber 2LLYY0406 and EPDM raw rubber have a certain gap, the complete use of EPDM reclaimed rubber, especially the low content of EPDM reclaimed rubber will cause the wiper strip indicators to reduce, The problem of hardening and aging in advance is easy to occur during use. Therefore, it is better for rubber product manufacturers to use EPDM reclaimed rubber together with EPDM rubber, which can not only ensure the performance characteristics of wiper strips, but also significantly reduce the cost of raw materials.
In order to further optimize the performance of wiper strip products, rubber product manufacturers are better to use EPDM reclaimed rubber with high content of EPDM unvulcanized rubber compound to increase the amount of EPDM and reduce the change under the premise of ensuring quality. High raw material cost. In general, the amount of EPDM reclaimed rubber in the EPDM wiper strip formulation can be controlled between 30-50%, or even more.
When using EPDM reclaimed rubber to reduce the production cost of wiper strips, rubber product manufacturers not only need to choose EPDM reclaimed rubber with appropriate indicators, to reasonably control the amount of reclaimed rubber, but also need to reasonably adjust the formulation of automotive wiper strips containing EPDM , Properly adjust the production process parameters to further improve the performance and service life of the wiper strip.
