The PURBlock Process is a discontinuous system for the production of single blocks of slabstock foam under variable pressure conditions.

PURBlock is a unique system for single blocks where the mould box itself is the vacuum/pressure chamber.

PURBlock includes Opus’ advanced design mixing system that gives improved cell structure and a specially designed mould base , based on the Maxfoam principle that is automatically lowered during foaming to give flat topped blocks and improved chemical distribution
