Flame-Retardant Grade PMMA
Flame-retardant grade PMMA incorporates halogen-free flame retardants (organic phosphorus-based, silicon-based, etc.) or reactive flame-retardant monomers to achieve UL94 V-2 to V-0 ratings, with some high-end products reaching 5VA level. This series maintains high light transmittance (≥88%) while meeting fire safety regulations for rail transit, construction, and electrical appliances. It is one of the fastest-growing functional PMMA varieties in recent years.
