摘要:
Novel, lubricious coatings for medical devices are disclosed. The coatings provide improved lubricity and durability, and are readily applied in coating processes. The present invention is also directed to a novel platinum catalyst for use in such coatings. The catalyst provides for rapid curing, while inhibiting cross-linking at ambient temperatures, thereby improving the production pot life of the coatings.
摘要:
An object is formed on a component with a positive flash shut-off during insert molding operations. The mold has a base with a cavity and a port that delivers a liquid to the cavity. The base has a component support structure for supporting the component and pockets formed on opposite sides of the cavity. The pockets are slightly spaced apart from the cavity by thin partitions. Inserts located in the pockets and are formed from a polymer. Both the partitions and inserts comprise the component support structure. The inserts have a dimension that is smaller than that of the base and partitions so as to form a compression fit around the component to reduce or eliminate flash down the component during the molding process.
摘要:
The disclosure is directed to a method of making a silicone composition includes mixing a silicone formulation in a mixing device and adding an in situ adhesion promoter to the mixing device. The disclosure is further directed to articles made from the above-mentioned silicone composition.
摘要:
The invention provides reinforced aerogel monoliths as well as fiber reinforced composites thereof for a variety of uses. Compositions and methods of preparing the monoliths and composites are also provided.
摘要:
The disclosure is directed to a sealing assembly. The sealing assembly includes a cap having a top surface and a bottom surface, an adhesive layer adjacent the bottom surface of the cap, and a septum adjacent to the adhesive layer. The adhesive layer includes a self-bonding silicone composition and the septum includes at least one fluoropolymer layer. The disclosure is further directed to methods for making the aforementioned sealing assembly.
摘要:
The disclosure is directed to a tube. The tube includes a silicone elastomer and at least one reinforcement member substantially embedded within the silicone elastomer. The disclosure is also directed to a tube including a first layer and a second layer adjacent the first layer. The first layer includes a fluoropolymer liner and the second layer includes a silicone elastomer and at least one reinforcement member substantially embedded within the silicone elastomer. This disclosure is further directed to a method for making the aforementioned tubes.
摘要:
An article includes a silicone formulation and an in situ softening promoter. The silicone formulation has a shore A durometer and the in situ softening promoter decreases the shore A durometer of the silicone formulation by at least about 35%.
摘要:
A flexible article includes a layer of a thermoplastic polyurethane composition including a plasticizer present at up to about 50.0% by weight of the total weight of the composition. The thermoplastic polyurethane composition has a shore A durometer of not greater than about 80. A method of making a flexible article includes combining a thermoplastic polyurethane with a plasticizer to form a thermoplastic polyurethane composition, wherein the plasticizer is present at up to about 50.0% by weight of the total weight of the composition; and forming the thermoplastic polyurethane composition into the flexible article, wherein the flexible article has a shore A durometer of not greater than about 80.
