Carbofill® is a two component phenolic foam resin used for filling cavities. 

Component A is an aqueous phenolic resins containing a suspension of solid carbonates as a blowing agent and Component B is a blend of various acids which affect the foaming process and the curing reaction. The final product is a lightweight material with a yellow to pink colour. Ideal for filling of cavities in underground roadways and longwalls and the stabilisation and prevention of gas accumulation, stabilisation of debris and forming temporary plug seals.
