Abstract: This article uses multiple factor analysis to design experiments and study the effect of the
dosage of BPP and bisphenol AF on the vulcanization characteristics and basic properties of fluororubber
(FKM). The results showed that within the experimental setting range, increasing the dosage of bisphenol
and BPP resulted in an increase in the crosslinking degree of FKM, an increase in the tensile strength and
100% elongation stress of the rubber material, while a decrease in the elongation at break. As the dosage of
bisphenol increases, the scorching time gradually increases, and the tensile strength of the rubber material
also increases accordingly; When the dosage of bisphenol exceeds 2 parts, the increase rate significantly
decreases; With the increase of BPP dosage, the scorching time gradually decreases, and the tensile strength
of rubber shows a trend of first increasing and then decreasing. The mathematical model designed based on
regression analysis can accurately predict the trend of FKM performance with changes in BPP and bisphenol
dosage.
