RDS-ACM Reclaiming Agent

Appearance: light grey powderACM rubber is a kind of special rubber produced by industrial production after 1983; the basic characteristics of ACM rubber lie in its good property of fuel oil resistance and lubricating oil resistance at high temperature (175—200℃）and it also has several kinds of gas resistance property, but has bad water resistance and cold resistance.ACM rubber is mainly used in automobile manufacturing industry to produce auto parts, such as various gaskets, diaphragms, oil seals and special rubber hoses, etc. With the development of the automobile industry as well as the automobile population, the ACM rubber consumption is also increasing. At the ACM rubber

is a kind of expensive rubber, under present world economy situation, the reclaiming and application of the ACM waste rubber is very significant to reduce the costs of the auto parts materials as well as to increase the economic benefit of the enterprise. The technique of manufacturing ACM by using the RDS-ACM reclaiming agent is simple and environmental, and can be finished with existing equipment of the rubber factory, and our company can provide the application company with technical guidance and training.ACM Rubber Reclaiming Technique：The open fining mixer or the refining mill→ put in waste ACM rubber→ RDS-ACM reclaiming agent→ times of mill running

Test Recipe：

Data Analysis and Conclusion:Seeing from the above data, both of the vulcanization speed and the Mooney viscosity of the ACM reclaimed compound rubber made by the RDS-ACM reclaiming agent substituting pure ACM raw rubber are very close to the compound rubber made by ACM raw rubber only. The physical property and hot air aging property are also very close to each other. So we can conclude that the ACM reclaimed rubber made by the RDS-ACM reclaiming agent can completely substitute part of ACM raw rubber. (Note: the waste rubber used by the reclaimed rubber is the trimming of 1# recipe.)
