A: Perspex and Lexan are both thermoplastics, which are types of plastic malleable above a specific temperature and that solidify when cool. Perspex is a brand of acrylic and Lexan is a brand of polycarbonate. The main differences between the two are price, impact resistance, UV resistance, clarity and availability of colours.
Lexan is the more expensive and more durable option, but will yellow over time, reducing its clarity, and it only comes in a limited range of colours. Perspex is more decorative, used in signage and as ornamentation and so comes in a wide variety of colours with a cheaper price tag. Let one of our staff advise you as to which is more suitable.
