TriphenylPhosphite

About this item

TriphenylPhosphite is a versatile aryl phosphite which can be blended in a variety oflubricants to improve antiwear and antifriction characteristics. It also functions as asecondary antioxidant and can provide superior stabilization when properly used withsuitable primary antioxidants. Its low viscosity allows for easy handlingand blending.
