WebApr 29, 2024 · Double endcapping means it is endcapped twice. Double (or triple) endcapping further minimizes silanol interactions and improves stability at mid pH. When developing methods in the mid pH range, it is recommended to use an endcapped column. As pH increases, silica dissolution is decreased by endcapping. WebIn a first aspect, the present invention is directed to a rubber composition comprising 70 phr to 100 phr of styrene butadiene rubber including a first styrene butadiene rubber having a glass transition temperature within a range of −49° C. to −15° C. and a second styrene butadiene rubber having a glass transition temperature within a range of −50° C. to −89° C.
