Pouring Foam is a flame retarded, NON‑CFC, two pack rigid polyurethane foam system producing foam with a nominal freerise density of 36‑38 kg/m3.

 Pouring Foam Polyol contains 141b ‑ HCFC 'Blowing Agent'. The ODP factor (Ozone Depletion Potential) for 141 B is 0.11.


 Pouring Foam is recommended for use as thermal insulation in cold and hot applications, from ‑50C to +85C temperature range.

 It is also suitable for use in 'buoyancy' applications ie. cavity/compartment/void filling for boats, wave‑skis, canoes etc. and in building panels, moulded fibreglass systems.

 It is suitable for moulding/void filling applications where low weight and increased stiffness/stability are required.

 It is suitable for pour‑in‑place or injection use by either 'hand' mixing or machine processing.


 It should be noted that the Pouring Foam Polyol component contains flame retardant chemical additives at a low level. It is not fire‑rated and foam produced from this system will burn while in contact with a flame or under high temperature conditions.

The Building Code of Australia sets out the requirementsluse conditions and guidelines for the use of these systems in commercial and industrial building applications.

 Reactivity Profile

 The figures set out are the laboratory quality control specification for the system at 200C based on 200gms of total mix mixed with a 50mm Disc Stirrer at 2,800 RPM.

Notes on Thermal Conductivity

In applications where impermeable facings are in place or applied to both faces eg. metal sheeting, metal foils, fibreglass lay‑up construction, and is adhered firmly over the whole surface of both sides of the foam, the foam will retain its

Initial k factor of typically 0.017/0.018 W/(m.K)   [0.015/0.016 kcal/(mh'C)]

 The R value ‑ Thermal Resistance on this basis is set out below

 Bayer AG Technical Literature indicates that at normal exposure temperature conditions %variations in thermal conductivity cannot be detected experimentally between (foam densities of) 30 and 60 kg/M3 . The variations due to differences in density are less than those caused by variations in the composition of the cell gas".
