Curatives & Accelerators

Curatives and Accelerators are crucial for the compounding of elastomers. Curatives are the cross-linking agents used to connect each separate virgin polymer. Accelerators increase the rate of cross-linking and therefore decreasing both production time and cost.

J. Allcock & Sons are the UK distributor for the Intercure® range, manufactured by Interbusiness S.R.L.
