Fluororubber Gaskets Recycling Process
Fluorine rubber has good heat resistance, weather resistance, ozone resistance and excellent chemical stability and is one kind of self-extinguishing rubber. It is widely used in the aviation, aerospace, guided missile, rockets and many other high-tech areas, so as in petroleum, chemical industry, machinery and instrument; as the speed of the automobiles is increasing, the use of fluorine rubber in automobile industry is wider and wider, and the consumption of the fluorine rubber is greater and greater. As the price of the fluorine rubber is expensive, so is that of the fluorine rubber products, the recycle of the waste fluorine rubber is a good way to reduce the cost of the fluorine rubber products. The RDFPM (II) fluorine rubber reclaiming agent technique is simple and has obtained good effect. Our company can provide the application company with technical guidance and training.

Data Analysis and Conclusion：
Seeing from the above test data, the vulcanization speed of the compound rubber added with 20 or 30 parts by weight of reclaimed fluorine rubber is lower than that of the compound rubber without adding any reclaimed fluorine rubber, but it is not obvious, just adjusting the vulcanizing system a little is fine. The physical property and the hot air aging property are very close to each other.
