DMA (CAS: 2680-03-7) is an ophthalmic material, also known as: N,N-dimethylacrylamide (N,N-dimethylacrylamide), the molecular formula is: C5H9NO, which can make the lens provide a high refractive index and good optical properties, so it is widely used in the manufacture of silicon hydrogel ** glasses, intraocular lenses, OK lenses, etc.
Silicone hydrogel** spectacle lenses with DMA (CAS:2680-03-7) monomer material offer many advantages such as high transparency, high elasticity and softness, and good wettability. At the same time, DMA has the characteristics of high transparency, high refractive index and low dispersion, which can enable the lens to provide clear vision.
Silicon hydrogel** spectacle lenses with DMA (CAS: 2680-03-7) monomer material have good histocompatibility with the human body, will not cause immune rejection, and can be retained in the human body for a long time. With good hardness and elasticity, it can withstand mechanical stress during use, is not easy to deform and break, and improves wearing comfort. It has good chemical stability and corrosion resistance in the physiological environment, and is not easy to be degraded and corroded. It can improve the wettability and anti-protein adsorption properties of the material, and reduce friction and discomfort between the eyes and the lens.
The demand for health and aesthetics is growing, and the eyewear market is also expanding. The demand for glasses materials is also increasing, DMA (CAS: 2680-03-7) ophthalmic materials as a high-performance material, with the continuous progress of science and technology and the increase in consumer demand for high-quality glasses, DMA glasses materials are expected to be applied in more ophthalmic fields and become one of the preferred materials for manufacturing high-quality glasses.
Huanosen has established an international cutting-edge and domestic well-known R&D, production and sales platform for silicone hydrogel glasses products and their special materials. The DMA (CAS: 2680-03-7) ophthalmic materials successfully developed by Huanasen have undergone nearly 20 on-site audits by world-class ophthalmology giants and other partners around the world, and have passed its quality management system certification, becoming the global designated supplier of many Fortune 500 companies.
