RDFPM Fluorine Rubber Reclaiming Agent

Appearance: light yellow irregular particleApplication：applicable to the reviving of the fluorine rubber under normal temperature..

Application Recipe:

Reclaiming Technique：1. Place the unqualified fluorine rubber products and production leftovers on the open mill after selecting, cleaning, removing sundries, drying and cutting into small pieces, break them with small roll pitch (≤0.2mm), and make them be fluorine rubber powder after selection and classification.2. Refine the fluorine rubber powder and the RDFPM fluorine rubber reclaiming agent on the open mill for 15-20 min, and corresponding softener can be added according to the condition, and after mill running and sheeting, the reclaimed fluorine rubber can be got.Storage life: in cool and dry places for 2 yearsPackage: 25kg/bag

RDFPM(II) Fluorine Rubber Reclaiming Agent

Appearance: blend of compound A light grey powder and compound B liquid.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.

Brief Introduction of Fluorine Rubber Reclaiming Technique：The refining mill→ put in waste fluorine rubber→ put in RDFPM(II) fluorine rubber reclaiming agent→ the process will be finished after the mill running.

Application Recipe Property of the Reclaimed Fluorine Rubber：

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.
