\n\n\t \n WHAT IS OPTICAL GRADE SILICONE? <\/span>\n<\/span>\n\n \n <\/span>\n <\/span>\n <\/span>\n<\/span>\n<\/h4>\n
\n
\n [vc_column_text]Optical grade silicone is an elastomer. Meaning, once it has hardened it can no longer be shaped. Vulcanised optical grade silicone is similar to glass and therefore used to manufacture lenses or lamps, for example. The high resistance to heat or weather conditions make it an ideal material for a large range of applications.[\/vc_column_text] <\/div>\n<\/div>

\n\n\t \n Where is optical grade silicone primarily used? <\/span>\n<\/span>\n\n \n <\/span>\n <\/span>\n <\/span>\n<\/span>\n<\/h4>\n
\n
\n [vc_column_text]Optical grade silicone is often used for state of the art LED lamps. One of the most common applications of optical grade silicone is the car. The properties of optical grade silicone allow the production of lenses which enable effective and efficient matrix LED, adaptive full beams or dynamic headlamp.[\/vc_column_text] <\/div>\n<\/div>

\n\n\t \n What are the properties of optical grade silicone? <\/span>\n<\/span>\n\n \n <\/span>\n <\/span>\n <\/span>\n<\/span>\n<\/h4>\n
\n
\n [vc_column_text]<\/p>\n
    \n
  • Both on the visible and on the UV spectrum, optical grade silicone is virtually as transparent as the best glass available (high refractive index)<\/li>\n
  • Considerably more resistant to scratches than glass, PC and PMMA<\/li>\n
  • Won\u2019t break, unlike glass, PC and PMMA<\/li>\n
  • No yellowing, thus the ideal material for outdoor applications<\/li>\n
  • High operating temperature range<\/li>\n
  • Resistant to ageing, heat and UV rays<\/li>\n
  • Lighter than glass, PC and PMMA<\/li>\n<\/ul>\n

    \n\n\t \n Is optical grade silicone a better glass? <\/span>\n<\/span>\n\n \n <\/span>\n <\/span>\n <\/span>\n<\/span>\n<\/h4>\n
    \n
    \n [vc_column_text]Optical grade silicone is superior to regular glass in many aspects.
    \nIts properties make optical grade silicone particularly far superior to glass in manufacturing lenses. In injection moulding the liquid silicone rubber vulcanises into a super-transparent elastomer. So the finished lens can let all of the incident light pass through. Precise injection moulding allows full control over the light. Entering and exiting light can be precisely refracted, focused or diffused. The numerous options to shape light are evident in the increasingly extroverted shapes of headlamps.[\/vc_column_text] <\/div>\n<\/div>

    \n\n\t \n What are other advantages of optical grade silicone? <\/span>\n<\/span>\n\n \n <\/span>\n <\/span>\n <\/span>\n<\/span>\n<\/h4>\n

    Silicone elastomers further do not absorb moisture and are electrically insulating. Their low viscosity is also beneficial, so consistent dimensions are considerably easier to achieve with silicone moulded parts than the corresponding glass parts.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

    Silicone elastomers can withstand extreme temperatures and extremely resistant to oxygen and ozone. They also withstand prolonged exposure to visible light and ultraviolet rays \u2013 unlike organic polymers they won\u2019t yellow.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
