A process forms an implantable product including poly(glycerol sebacate) urethane (PGSU) loaded with an active pharmaceutical ingredient (API). The process includes homogeneously mixing a flowable poly(glycerol sebacate) (PGS) resin with the API and a catalyst to form a resin blend. The process also includes homogeneously combining the resin blend with an isocyanate to form a reaction mixture and injecting the reaction mixture to form the PGSU loaded with the API. An implantable product includes a PGSU loaded with an API. In some embodiments, the implantable product includes at least 40% w/w of the API, and the implantable product releases the API by surface degradation of the PGSU at a predetermined release rate for at least three months under physiological conditions. In some embodiments, the PGSU is formed from a PGS reacted with an isocyanate at an isocyanate-to-hydroxyl stoichiometric (crosslinking) ratio in the range of 1:0.25 to 1:1.25.

A medical airway device having a cuff is manufactured by loading an injection molding apparatus with a thermosetting elastomeric material and shaping the cuff by injecting the material into an associated injection mold. The injection mold includes a sprue bush having a sprue passage in fluid communication with a mold cavity. The injection molding apparatus includes an injection nozzle that is positioned in contact with, or in close proximity to, the sprue bush. The thermosetting elastomeric material is discharged from the injection nozzle through the sprue passage and into the mold cavity. The cuff is formed by curing the thermosetting elastomeric material within the mold cavity and at the same time preventing premature curing of residual thermosetting elastomeric material within the injection nozzle by applying heat to the material within the mold cavity while cooling the injection nozzle with cooling fluid. The formed cuff is attachable to an airway tube.

Compositions are provided comprising A) at least one polymer selected from the group consisting of aromatic polycarbonate and aromatic polyester carbonate, B) at least one mixture comprising at least one butadiene-based graft polymer prepared by emulsion, suspension or solution polymerization and at least one polybutadiene-free vinyl (co)polymer, and C) at least one polymer additive, where the polybutadiene content based on the sum total of the parts by weight of components A and B is 10% to 20% by weight, and where the total content of butadiene-free vinyl (co)polymer from component B based on the sum total of the parts by weight of components A and B is 12% to 23% by weight. Composite components formed from these compositions and a polyurethane layer, which are notable for improved adhesion between the two layers, and a process for producing the composite components are also provided.

The present disclosure relates to machines and methods for reaction injection molding. In particular, the present disclosure provides small format reaction injection molding machines having exchangeable molds and reactant material tanks, as well as molds configured for use therein and associated componentry. In one example, a reaction injection molding machine can include a housing, at least one reactant materials tank engagement station in operational engagement with a first reactant material tank, a molding support framework, an injection molding manifold, and an injection molding nozzle engagement station.

The invention relates to a device assembly and methods useful for producing molded silicone rubber products from liquid silicone rubber compositions (LSR) via injection molding. The methods provide a flexible process to produce faster cured silicone rubber products from LSR and allow for use of low curing temperature in the molding cavities without drastically lowering cure speed of the LSR and the physical properties of the produced molded silicone rubber material, therefore allowing liquid silicone rubber overmolding on or over heat sensitive substrates. The device assembly of the invention allows a faster cycle and the use of precise dosing and mixing units thus creating a flexible process to produce cured silicone rubber products faster from liquid silicone rubber (LSR).

The invention relates to a method for producing a protective sound panel for a motor vehicle.
