Abstract:
In one aspect, a self-lubricating component is provided for a pharmaceutical packaging assembly. The self-lubricating component comprises a polymer composition and an effective amount of a lubricating additive such as, for example, boron nitride. In another aspect, a pharmaceutical packaging assembly may be provided having a surface thereof coated with a lubricating composition comprising boron nitride. The pharmaceutical packaging composition may be, for example, a pre-filled syringe comprising a body (barrel) and a plunger assembly.
Abstract:
An α,ω-functionalized polyoxyalkylene-siloxane polymer having the general structural Formula (I): provides improved hydrophilicity and hemocompatibility. The α,ω-functionalized polyoxyalkylene-siloxane polymer may be used to make various polycarbonate/α,ω-functionalized polyoxyalkylene-siloxane copolymers and polymer blends, as well as articles including such copolymers and blends.
Abstract:
The present technology provides a coating system including an inorganic UV-absorbing material and a catalyst. The inorganic UV-absorbing material is chosen from cerium oxide, titanium oxide, zinc oxide, or combinations of two or more thereof. The inorganic material may be provided ranging from 1 wt. % to about 50 wt. % based on the dry weight of film after curing the coating system. The catalyst is provided in an amount ranging from 1 ppm to about 75 ppm. The coating system may include a topcoat material, a primer material, or a combination thereof.
