Compared with butyl rubber, chlorinated butyl rubber has better vulcanization performance and compatibility with other rubbers, and can be used in the preparation of various soft rubber compounds; Manufacturers can use chlorobutyl rubber alone or in combination with other types of rubber. Xiaobian today shares with you several applications of chlorobutyl rubber in soft rubber compounds.
1. Chlorobutyl rubber alone
Chlorinated butyl rubber can be used in many fields such as inner tubes, innerliners, tire sidewalls, anti-corrosion linings, and industrial shock-absorbing products. When chlorinated butyl rubber is used alone to prepare soft rubber compounds, rubber product manufacturers can choose low-sulfur vulcanization or sulfur-free vulcanization systems. Appropriate use of barium sulfate or precipitated barium sulfate can significantly improve the acid and alkali resistance of soft rubber compounds, such as Acid-resistant lining with chlorobutyl rubber as the main material.
2. Chlorobutyl rubber + EPDM rubber
Blending appropriate amount of EPDM rubber in the butyl rubber formulation can alleviate the problem of aging, softening and stickiness of butyl rubber products, and then extend the service life of rubber products. Chlorinated butyl rubber retains the basic performance characteristics of butyl rubber and can be used together with EPDM rubber to further improve the comprehensive performance of soft rubber compounds, especially high and low temperature resistance, aging resistance and ozone resistance. The performance and service life of soft rubber.
3. Chlorobutyl rubber + EPDM rubber + recycled rubber
When chlorinated butyl rubber and EPDM rubber are used to prepare soft rubber compounds, rubber product manufacturers can also add an appropriate amount of reclaimed rubber, especially butyl reclaimed rubber or chlorinated butyl reclaimed rubber, to replace Partially chlorinated butyl rubber 2LLYY0413 reduces raw material costs. When chlorinated butyl rubber / EPDM / butyl reclaimed rubber is used to produce soft rubber, the amount of butyl reclaimed rubber is determined according to the actual situation. Generally, 10-20 parts of butyl reclaimed rubber can be added to 100 parts of original rubber , Can ensure the performance of soft rubber materials, and can reduce raw material costs.
When chlorinated butyl rubber is used as the main raw material to prepare soft rubber, rubber product manufacturers must choose the appropriate production method according to actual needs. When chlorinated butyl rubber and EPDM rubber are used together, if the cost budget is very low, rubber product manufacturers can also replace EPDM raw rubber with EPDM reclaimed rubber, which is more cost-effective and further reduces raw material costs. Later editors will have time to continue to discuss with you how to use recycled rubber to reduce more raw material costs when preparing chlorobutyl rubber for soft rubber compounds.
