摘要:
A granular composite additive for polyolefins which has a strength and a function which enable the additive to be dust-free and be of one-pack type. It comprises 10 parts by weight of a nucleating agent comprising an alkali metal salt or hydroxyaluminum salt of an aromatic monocarboxylic acid or comprising an alkali metal salt or hydroxyaluminum salt of an acid aromatic phosphoric ester compound, 1 to 50 parts by weight of a phenolic antioxidant, 5 to 50 parts by weight of polypropylene, and 0 to 500 parts by weight of one or more other additives as optional ingredients.
摘要:
High purity synthetic quartz glass particles are derived from alkali metal silicate and have a total amount of metal impurities content of at least 1 µg/g and, in particular, have oxygen-deficient defects. The high-purity synthetic quartz glass particles having high viscosity similar to natural quartz and high-purity similar to known synthetic quartz can be provided at a low cost.

摘要:
The present invention provides a multi-component granular additive for polyolefins which has a strength and a function which enable the additive to be dust-free and be of components-in-granule type. It comprises 10 parts by mass of a nucleating agent comprising an alkali metal salt or hydroxyaluminum salt of an aromatic monocarboxlylic acid or comprising an alkali metal salt or hydroxyaluminum salt of an acid aromatic phosphoric ester compound, 1 to 50 parts by mass of a phenolic antioxidant, 5 to 50 parts by mass of polyproylene, and 0 to 500 parts by mass of one or more optional additive components other than the nucleating agent and the phenolic antioxidant.
摘要:
A hydrous silica gel is dehydrated by freezing, thawing, and removing water separated by thawing, thereby yielding silica particles. In addition, the silica particles thus formed is washed and fired, thereby producing a synthetic quartz glass power. A water glass is dealkalized, an oxidizing agent and an acid are added, the mixture thus formed is passed through a hydrogen type cation exchange resin, the aqueous silica ,solution thus formed is then gelled, and the gelled material is then washed and fired, thereby producing a synthetic quartz powder. Silica is sequentially held for a predetermined time at each temperature range of 150 to 400°C, 500 to 700°C, and 1,100 to 1,300°C, thereby producing a quartz glass.
摘要:
A nucleating agent containing a phosphoric acid aromatic ester metal salt represented by formula (I) and having an average major-axis length of 10 µm or less, an average aspect ratio of 10 or less, and a bulk specific gravity of 0.1 or more: (wherein R 1 represents C4-C8 alkyl group, R 2 represents hydrogen or C1-C8 alkyl group, R 3 represents C1-C4 alkylidene group, A is a metal having a valence of n, and n is an integer of 1 or 2). The nucleating agent exhibits excellent handling property when incorporated into a resin, and is highly effective in improving transparency and mechanical strength of the resin containing the agent.
