There are dozens or even hundreds of rubber sealing products in each car, mainly including rubber sealing strips, skeleton oil seals, O-rings, product cups, brake films, dust covers, and various special-shaped sealing rings, etc. A large part of it is processed with EPDM as the main raw material, and the finished product has excellent aging resistance. EPDM reclaimed rubber retains the basic performance characteristics of EPDM rubber, high and low temperature resistance, weather resistance, and ozone resistance. It can replace a certain proportion of EPDM rubber to prepare various automotive sealing products.
1. Car sealing strip
Automobile sealing strips are mainly used for vehicle doors and windows, engine cover boxes, trunks, etc., to prevent dust, water, vibration, and sound insulation, including door frame sealing strips, headway sealing strips, trunk lid sealing strips, Rear partition sealing strip, etc. According to the structure, it can be divided into solid sealing strip, sponge sealing strip and composite sealing strip. The performance requirements of the sealing strips in different applications are different. It is necessary to select the appropriate rubber raw materials and reasonably design the process formula and production parameters of the automobile sealing strips.
In actual production, most car sealing strips can use EPDM rubber, especially car door frame sealing strips, windshield sealing strips, sponge sealing strips for car doors, and window sealing strips. When using EPDM reclaimed rubber 2YLYY64 to reduce the cost of raw materials for automotive sealing strips, rubber product manufacturers should choose EPDM reclaimed rubber that is close to the finished product of the sealing strip, reasonably determine the ratio of reclaimed rubber to virgin rubber, and adjust the rubber sealing strip formula appropriately , Especially the vulcanization system and reinforcement system.
2. Hydraulic rubber brake cup
Automobile brake cups and aprons are mainly used in automobile hydraulic brake systems, used in automobile power steering and clutch sub-cylinder systems, to transmit power and seal. Brake fluid is the fluid that transmits pressure in the automobile hydraulic system and enables the wheel brake mechanism to achieve the braking effect. There are mainly three types of alcohol brake fluid, mineral oil brake fluid and synthetic brake fluid. Among them, EPDM rubber can be used for leather cups that use synthetic brake fluid under high temperature, and proper addition of EPDM reclaimed rubber can effectively reduce the cost of raw materials.
When using EPDM reclaimed rubber and EPDM virgin rubber to prepare synthetic brake fluid-resistant brake cups, it is recommended to use sulfur and DCP together in the vulcanization system, and medium and super wear-resistant carbon black can be selected for reinforcement. The usage editor will discuss with you in detail later.
EPDM reclaimed rubber is mainly used in the production of automotive sealing strips. The use of virgin rubber can effectively reduce the cost of raw materials under the premise of ensuring product quality. In actual production, EPDM reclaimed rubber can also be used in the production of some automobile rubber O-rings, gaskets, rubber sheaths, and rubber dust covers. I have the opportunity to continue discussing with you.
