摘要:
A composition including a) rubber, b) crosslinking agent, c) metals and/or chalcogenides of metals as crosslinking aids and/or antiaging agents is described, wherein at least one of components b) or c) is in the form of composite particles composed of carrier particles to whose surface particles of the active material having an average diameter of less than 25 μm are applied and layers thereof having an average layer thickness of less than 25 μm and/or conglomerates of multiple carrier particles to whose surface particles of active material having an average diameter of less than 25 μm are applied or layers thereof having an average layer thickness of less than 25 μm and d) optionally other conventional additives. The composite particles make it possible to lower the active material content while achieving comparable properties or improving the aging resistance of elastomers and/or increasing productivity.
摘要:
The invention relates to a composite particle made of carrier particles having an average diameter of less than 5 μm. Said particle composite is surrounded by a layer made of oxidic material having an irregular surface. Particles, which are made of an active material and which have an average diameter of less than 1 μm are applied to said layer. The composite particle can be used as a filling substance in polymers and enables the content of active material for comparable properties to be reduced or improves the properties of filled materials, e.g. resistance to aging of elastomers.
摘要:
A sheet consisting of a carrier medium, where at least one antimicrobial substance is incorporated into the carrier medium, is, in view of the task of specifying a sheet that exhibits high reactivity of the antimicrobial substance, characterized by the fact that the substance is in colloidal and/or nanoscale form. Moreover, the sheet is characterized by the fact that the substance is contained in a layer that is at least area wise interrupted or consists of unconnected partial layers. Moreover, a use of the sheet as a cleaning article or in a cleaning article is described.

A damp-wiping cloth (e.g., a sponge or the like) from a foam body of flexible foam material, the foam body (2) being interspersed with foam strips (3) whose hardness is greater than the hardness of the foam body (2).
摘要:
Disclosed are liquid impregnated sheets containing a combination of split-fibres and/or meltblown fibres with regular fibres of thermoplastic polymers. The sheets can be monolayers or multilayers with non-wovens of split-fibres on the outer portions of the multilayered sheets. The sheets possess good storage and release characteristics for a liquid and can be used as cleansing sheets for personal care or for polishing purposes.
