Polyurethane new technology helps high folding resin lens

recently, Wanxin optics joined hands with Mitsui chemical, one of the world's three major chemical enterprises, to vigorously create 1.60, 1.67 and 1.74 high folding products in the field of resin lens in China. The investment capital of the whole project is about 260million yuan, and the production plant covers an area of more than 20000 square meters. The project is expected to be completed by the end of December this year. At present, the plant construction has officially started

Wanxin's cooperation with Mitsui this time mainly focuses on: resin lens production materials mr-7, mr-8, and mr-174. Mr-7, Mr shale gas, shale oil, coalbed methane, tight gas and other unconventional oil and gas resources development 8. Mr-174 is the world's leading material for high refractive resin lenses synthesized by polyurethane technology. The lenses produced by the three materials are famous for their small chromatic aberration and high transmittance. At the same time, mr-7, mr-8, mr-174 also have strong processability, which are suitable for any lens, and the coloring of lens substrate is also extremely easy. Mr-7, mr-8 and mr-174 not only have excellent optical properties, but also have extremely high hardness, which makes the resin lens light and not easy to wear. At present, there are two kinds of materials for producing high break lenses, one is acrylic, and the other is polyurethane. The majority of domestic lens manufacturers use Korean polyurethane materials for high break lenses, and the material performance is slightly inferior to the high break materials developed by Mitsui, which is adopted by Wanxin this time

Mitsui has reached the world-class level in the research and development of polyurethane technology. Mr-7, mr-8 and mr-174 materials synthesized by polyurethane technology alone have obtained 300 patents. It can be seen that the resin lens produced by using this material has a high scientific and technological content. Ouyang Xiaoyong, vice president of Wanxin optical production, said that the 1.60, 1.67 and 1.7 produced in small batches with mr-7, mr-8 and mr-174 materials were used to reduce the waste of resources. 4 the lens quality exceeded the previously predicted effect. It is believed that the launch of the three high discount products will become the leader in the same grade of lenses. When wearing these three high break lenses, especially for those consumers who love sports, the impact resistance of the lenses will also bring them a more practical experience
