Processing method of acrylic lens and PC lens

Acrylic board from methyl methyloleate monomer (PMMA) polymerization, namely polymethyl methacrylate (PMMA) plate plexiglass, is a special process of plexiglass.It has the reputation of "Queen of plastic".The research and development of acrylic has a history of more than 100 years.

Acrylic lens has the advantages of light weight, low price and easy to shape.Its molding methods include casting, injection molding, mechanical processing, acrylic hot molding, etc., especially injection molding, can be mass production, the process is simple, low cost.Therefore, its application is becoming more and more extensive. At present, it is widely used in instrument and meter parts, automobile lamp, optical lens, transparent pipe and so on.

PC lenses, common resin lenses are thermosetting materials, that is, the raw material is liquid, after heating into a solid lens.PC lens is also called "space piece", "universe piece", chemical name is polycarbonic acid, is a thermoplastic material.That is, the raw material is solid and the lens is shaped after heating. Therefore, the finished lens will be deformed after excessive heating, which is not suitable for high-humidity and hot occasions.

PC lens has extremely strong toughness, not broken (2cm can be used for bulletproof glass), so it is also called safety lens.At just 2 grams per cubic centimetre, it is the lightest material currently used for lenses.

PC space lenses are lenses made of polycarbonate, which are essentially different from ordinary resin (CR-39) lenses. The common name of PC is bulletproof glass, so PC lens inherits the excellent characteristics of super impact resistance of raw materials, and due to the high refractive index and light specific gravity, the weight of the lens is greatly reduced, and there are more advantages such as: 100% anti-impact Ultraviolet rays will not turn yellow within 3-5 years (ordinary resin will turn yellow after a few months). If there is no problem in the process (for example, the domestically produced Lange brand PC space lens), the weight is 37% lighter than the ordinary resin sheet, and the impact resistance is up to 12 times that of the ordinary resin!
