Acrylic is very scratch resistant compared to other clear plastics. Acrylic sheet is a lighter alternative to glass and an economic substitute for polycarbonate in applications where strength is not a crucial factor.Acrylic is an incredibly useful plastic for applications requiring transparency where high impact resistance is not an issue. It can be cut into extremely fine shapes using laser cutting technology because the material vaporizes upon impact with the concentrated laser energy.Standard grades are rated as slow burning, but a special self-extinguishing grade of sheet is available. Although acrylic plastic weighs less than half as much as glass, it has many times greater impact resistance. As a thermal insulator, it is approximately 20% better than glass. It is tasteless and odourless.
