Balancing oxygen permeability with moisturizing properties remains a significant challenge in the industry.Pharnorcia® NVP (CAS: 88-12-0), also known as N-vinylpyrrolidone, is widely recognized in the industry as a moisturizing ophthalmic monomer material due to its exceptional hydrophilic properties.

The technical core of NVP (CAS: 88-12-0) lies in its excellent hygroscopicity and water solubility.During the molecular chain polymerization process, it rapidly forms an efficient network of water molecule retention within the lens matrix, endowing the lens with exceptional water-retention properties.

Pharnorcia® NVP (CAS: 88-12-0) is commonly regarded as the "moisturizing powerhouse."Its core contribution lies in significantly enhancing the lens's balanced water content by capturing moisture from tears, thereby alleviating dryness during wear.It serves as the foundation for many mainstream long-lasting, comfortable lenses.

As a pioneer in the global ophthalmic materials industry, Pharnorcia upholds the core values of high quality, globalization, and sustainable development, continuously driving technological advancement in this field.When you need these materials, simply call or email us, and we will contact you as soon as possible.
