Now more and more butyl inner tube manufacturers began to add reclaimed rubber in the inner tube of butyl, one can improve the processing technology and performance of butyl inner tube, and secondly, it can reduce the cost of raw materials, which is an accomplishment in one fell swoop. There is mainly two parts about the content of reclaimed rubber products in butyl inner tube: one is the amount of butyl rubber and the other is the amount of reclaimed rubber of EPDM.
1, on the butyl inner tube butyl rubber regeneration dosage
Butyl reclaimed rubber is a kind of reclaimed rubber processed from waste butyl inner tube, which has the properties of butyl rubber. Its appearance is mainly to reduce the raw material cost of the manufacturers who use butyl rubber as raw material to produce butyl inner tube. Maybe you will ask: Some butyl inner tube manufacturers mixed with about 50% butyl rubber regeneration, some manufacturers use about 30% butyl rubber instead of reclaimed rubber, what the best dosage? In fact, different manufacturers, different butyl inner tube of butyl rubber products with the proportion of mixed is not necessarily:
For example, some large inner tube can be mixed with about 90% butyl rubber, while some small tire inner tube butyl rubber reclaimed rubber mixing ratio is usually about 50%, for less demanding low-grade butyl inner tube can even be used completely Based reclaimed rubber; it is learned that domestic well-known small tube manufacturing enterprises will also be mixed with butyl rubber in the production process, the amount of 10% -15% range.
2, on the inner tube of ethylene-propylene rubber reclaimed rubber mixed dosage
EPDM reclaimed rubber retains the EPDM rubber high temperature resistance, anti-aging properties, in a small amount of butyl inner tube EPDM reclaimed rubber can significantly improve the aging of the soft inner tube, air tightness decreased Problem, extend the life of butyl inner tube. Under normal circumstances: EPDM reclaimed rubber doping amount of about 10 %%, the amount of too much, will result in the reduction of airtight butyl tube consequences.
Therefore, when the butyl inner tube is blended with reclaimed rubber, neither too much nor too little, and the overall butyl inner tube product performance and manufacturer's cost budget, seeks for an optimal blending scheme for reclaimed rubber in a butyl inner tube.
