Smithers Oasis Engineered Product Properties
Close-up of closed-cell phenolic foam
Close-up of open-cell phenolic foam
Smithers phenolic foam is an expanded foam with controllable cell size. Phenolic foam can be molded into different shapes and sizes with ordinary working tools. It is self-extinguishing and exhibits fire retardant properties. It is excellent as a thermal insulation foam and capable of meeting international building regulation requirements.

Properties include
- Controlled cell size foam
- Closed or open cell foam
- Excellent strength to density relationship
- Self-extinguishing and exhibits fire retardant properties
- Excellent as thermal insulation
- Capable of meeting international building regulation requirements
- Non-flammable, but will support combustion by direct contact with open flame or exposure to temperature in the range of 315°C (600°F)
- Can be carbonized
- For thermal conductivity, the closer the cells to each other, the less transfer of heat from one to another
