1. High transparency. PMMA extruded lens is considered to be the best polymer transparent material. Since the light transmittance reaches 92%, which is higher than that of glass.
2. High mechanical strength. The relative molecular content of PMMA extruded lenses is about 2 million. It is a long-chain polymer compound with soft molecular forming chains. Therefore, PMMA extruded lenses have higher strength, and their resistance to stretching and impact is better than ordinary material.
3. Lightweight. The density of the PMMA extruded lens is 1.18kg / dm3, it is just half of the ordinary glass and 43% of metal aluminum (attributable to light metals).
4. Easy to process. PMMA extruded lenses can not only be cut with a lathe, drilled with a drill, and can be bonded into various shapes .
