RAV 7 NG is the trade name for a special allyl carbonate monomer (RAV 7). It can be cast polymerized in the presence of organic percarbonate initiators in the same way as standard allyl diglycol carbonate (ADC) monomer. On polymerization, RAV7 NG develops a rigid organic glass through a highly bonded network structure.
