| titleOfInvention |
Process for the manufacture of a flame resistant, insulating, energy-absorbing, porous phenolic foam |
| abstract |
A high compressive strength phenolic resin foam is made by: adding between about 0.5 to 5.0 parts of a dual surfactant system and about 8 to 25 parts of a blowing agent, to 200 parts of a phenolic resole resin to form a pre-mix; agitating this pre-mix with about 20 to 70 parts of an aqueous dual sulfuric-phosphoric acid solution to provide a foaming phenolic material; immediately thereafter pouring or injecting the material into a mold or onto a suitable substrate, to provide a phenolic foam having a substantially uniform compressive strength of at least 40 psi. at between about 20% to 50% compression, at a deflection rate of between about 2 in./min. to about 5 in./min. |
