RDFPM Fluorine Rubber Reclaiming Agent
Appearance: light yellow irregular particle
Application：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 years
Package: 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.

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.
