摘要:
A composite material includes a matrix composed of a polyhydroxyalkanoate (PHA) polymer and a filler composed of particles dispersed in the matrix. The particles are composed of naturally-derived materials (e.g., ground bone meal or pumice powder), have a microporous microstructure, have a low hygroscopic expansion, and are less than 1.0 mm in size. Preferably, the matrix and the filler together constitute 100% by weight of the composite material, and at most 30% by volume of the composite material is consumed by the filler. The composite material may take the form of an anaerobically biodegradable article of manufacture such as a building material a coating of a building material or other article.

摘要:
The invention concerns a silicone composition cross-linkable by hydrosilylation into adhesive gel and absorber, characterized in that it comprises: (I) at least a polyorganosiloxane POS (I); (II) at least a polyorganosiloxane POS (II); (III) at least an adhesive promoter (III); (IV) hollow organic microspheres; (V) optionally at least a polyorganosiloxane POS (V) particularly useful as diluent of POS (I); (VI) an effective amount of hydrosilylation catalyst, preferably of the platinous type.
摘要:
A method of manufacturing thermosets such as epoxy resins includes adding expandable hollow microspheres, which expand with temperature as shown in the accompanying graph, to the base thermoset components in the liquid phase and applying heat treatment to the mixture so formed causing the micropsheres to expand during or after curing of the thermoset. This results in a toughening mechanism caused by compressive residual stress around the microspheres which significantly increases the specific fracture energy of the epoxy resin.
