Methacrylate monomers for Health Care
Soft contact lenses are hydrogels consisting of hydroxyesters, crosslinkers and other comonomers to increase hydrophilicity.
VISIOMER® UHP HEMA (ultra high-purity hydroxy methacrylate) enables the production of dimensionally stable soft contact lenses with high wear comfort. This is achieved by combining high oxygen permeability with high water uptake. VISIOMER® UHP HEMA is often used in combination with crosslinkers, such as VISIOMER® EGDMA, PEG200DMA, TRGDMA and GMMA for this application.
