Composed of 80% calcium oxide powder dispersed in 20% EP rubber, this new masterbatch from Birch Chemicals is delivered in a granule-based form for consistent addition control, super-fast mixing and exceptional dispersion, with no waste or spillage.

Innovox® MB features none of the inactive ingredients (oils and waxes) of competitor products, guaranteeing a reliable solution for porosity, surface blisters and other moisture-related issues.

A specific additive bespoke version can be created, offering a significant competitive advantage. Innovox® MB is packaged in low-melt sachets, available in 1kg bags (despatched in 20kg boxes) or in larger 25kg bags.
