PURL SJ-64 is a rigid medium density polyurethane foam system formulated to be processed through a suitably designed 1:1 v/v ratio polyurethane machine. This system produces a medium density rigid foam product. It is suitable to be used to fill voids and other structures as well as lift and stabilise concrete.
The actual in-situ density achievable is dependent on the application size / configuration of the void, the restriction to flow and load applied above the rising foam.
PURL SJ-64 System contains no HFC or HCFC Blowing Agents.
