ChemSpec Enhances Product Solutions with Videos


The enclosed videos bring a solutions perspective for customers utilizing VULCOFAC® REC MB80 (80% actively dispersed evenly into an EPDM compound). 

VULCOFAC REC MB80 is a retarder used to improve the processing safety of compounding by prolonging flow times at cure temperatures. It is an excellent anti-scorching agent for natural rubber and synthetic rubber, especially for EPDM, NBR, and HNBR. It is presented as a masterbatch on an EPDM binder for improved handling, absorption, and dispersion in a rubber mix.

“I am confident our in-house videos will be an important tool in helping our customers find a solution to a problem.  The progress our sales and marketing teams are making in efforts to enhance our customer relationships is outstanding.” explains Dave Moreland, President & CEO of ChemSpec, Ltd.
