Polycarbonate LED Diffusers
Polycarbonate for impact resistance, temperature resistance and demanding environments.
Material
Why polycarbonate
Polycarbonate is specified when the diffuser has to survive impact, higher temperatures or rough handling. It has very high impact strength and a higher continuous service temperature than PMMA, at the cost of slightly higher haze and a softer surface that needs care in handling. UV-stabilised and flame-retardant grades are available.
Comparison
