What is the difference between flame retardant acrylic and ordinary acrylic

Flame retardant acrylic refers to plexiglass that does not burn or burns slowly and extinguishes itself after leaving the flame. It is an environmentally friendly new material. It combines the advantages of plexiglass (acrylic) and polycarbonate (PC), and its strength And impact toughness is better than plexiglass, and it is widely used in buildings with higher fire protection requirements.

The flame retardant performance of acrylic is determined by the oxygen index. The oxygen index is generally greater than 25 (ordinary plexiglass is 17.5). In the prepared prepolymerized slurry, the casting mold is polymerized.

What is the difference between flame retardant acrylic and ordinary acrylic:

1. Different flame retardant effects

Common acrylic material itself is not flame retardant. Acrylic flame retardant material, as the name suggests, is to increase the flame retardant to prevent rapid burning, which has a better flame retardant effect than ordinary materials.

2. The burning speed is different

Acrylic flame-retardant materials, compared with ordinary acrylic materials, will not burn so quickly and completely.

3. The extinguishing time is different

Acrylic flame retardant materials will quickly extinguish after burning, while ordinary acrylic materials will not self-extinguish, but will only burn out quickly.

Acrylic is an important plastic polymer material developed earlier. It does not self-ignite but is a flammable product. It is easy to burn, with a limiting oxygen index of only 17.3, and it does not have self-extinguishing properties.
