A water-soluble film comprising a mixture of a polyvinyl alcohol (PVOH) resin, a plasticizer, and a metal salt, wherein the metal salt is present in the water-soluble film in an amount sufficient to reduce the enthalpy of melting of the film by at least 20% compared to the enthalpy of melting of an otherwise identical film not comprising the metal salt.

The present application relates to a polypropylene (PP) composition comprising a) 50.0 to 95.0 wt.-%, based on the total weight of the polypropylene (PP) composition, of a polypropylene (PP) homopolymer being polymerized in the presence of a single-site catalyst and b) 5.0 to 50.0 wt.-%, based on the total weight of the polypropylene (PP) composition, of a mineral filler, to an article comprising the polypropylene (PP) composition as well as the use of the polypropylene (PP) composition for improving the thermo-mechanical properties.

A non-baked pencil lead including a wax that is solid at normal temperature, a colorant, a filler, a water-soluble resin, and a cellulose fiber, wherein a ratio of a flaky substance in the filler is 20 mass % or less, and the ratio of an aggregate particle in the filler is 80 mass % or more.

An insulating, compressible, and flame-resistant foamed material is provided. It comprises a polyorganosiloxane foam, a fire retardant, and expanded perlite. The foamed material is useful for providing heat insulation, flame resistance, and compressibility for applications such as lithium-ion batteries.

A rubber composition that includes a rubber component, an inorganic fiber material, and a coupling agent. The inorganic fiber material is one or more inorganic fiber materials selected from the group consisting of a magnesium sulfate fiber, a calcium silicate fiber, a potassium titanate fiber, an aluminum borate fiber, and a glass fiber.

The degradation promoter for an aliphatic polyester biodegradable resin according to the present invention contains basic magnesium sulfate.
