摘要:
There are instruments used for handling a substrate in a clean room at room temperature and atmospheric pressure, which contain a resin base and at least one additive selected from the group consisting of a lubricant, a plasticizer, an anti-oxidizing agent and an antistatic agent, and the additives do not generate gaseous organic material compound under conditions of room temperature and atmospheric pressure.
摘要:
An electronic/electric part used in a clean room in which the atmosphere is controlled to process a substrate in a semiconductor device industry, which contains a resin base material and additives added to the resin base material. The additives contain one or more materials selected from the group consisting of an anti-electrostatic agent made of a nonionic compound of a molecular weight of 350 or higher, an anti-oxidizing agent made of a phenolic compound of a molecular weight of 300 or higher, a lubricant, a plasticizer, a fire retardant, and a water repellent. The additives hardly releases gaseous organic substances from the resin base material under a condition where the part is used.
摘要:
A material not releasing gaseous organic substances during use is used as a filter medium and a sealing material for tightly sealing between the medium and a frame. Specifically, a synthetic paraffin not containing an aliphatic hydrocarbon having not more than 19 carbon atoms or less is used as a non-silicone type water repellent contained in a treatment agent for forming fibers into a cloth-like filter medium. A carboxylic acid ester having 400 or more molecular weight is used as a plasticizer and a phenolic compound having 300 or more molecular weight is used as an antioxidant to be added to the treatment agent and the sealing material. This enables that the gaseous organic substances are not present in a clean room, a semiconductor production apparatus or the like. Further, if the filter medium and the sealing material are formed of a material not releasing organic phosphorus compounds and boron compounds in the air, a clean room and a local facility particularly suitable for use in the production of semiconductors are provided.
摘要:
Materials not releasing gaseous organic materials during use are used as a dry-type sealing material such as a gasket disposed upon mounting an air filter to an opening of a ceiling or the like, a wet-type sealing material filled and used in a gap for connecting wall materials or partitionings, a vinyl chloride sheet or a vinyl chloride cloth as a facing material for walls and floors. Specifically, a carboxylic acid ester having a molecular weight of not less than 400 is used as a plasticizer, a phenolic compound having a molecular weight of not less 300 is used as an antioxidant, an aliphatic hydrocarbon having not less than 19 carbon atoms (for example, microcrystalline wax) is used as a lubricant, and an alkylamine ethylene oxide adduct having a molecular weight of not less than 350 is used as an antistatic agent.

摘要:
An electric wire with coating of polyvinyl chloride family resin composition is characterized by having a coating layer including polyvinyl chloride family composition obtained from adding more than one of any calcium soap, zinc soap and hydrotalcite to resin including polyvinyl chloride resin as a main constituent, and further adding thereto plasticizer so as to obtain a heat-stable vinyl chloride composition, and further adding thereto as stabilization auxiliaries high-melting-point β-diketone compound having a melting point more than 100° C. out of β-diketone compounds expressed by a general formula of R.CO.CH2.CO.R′.
摘要:
An electric wire with coating of polyvinyl chloride family resin composition is disclosed which has a coating layer containing a polyvinyl chloride family resin composition comprising polyvinyl chloride family resin and one or more compounds selected from calcium soap, zinc soap and hydrotalcite. The polyvinyl chloride composition does not comprise either or both of a lead compound and a β-diketone compound having a melting point less than 100° C. A plasticizer can be further added to the composition so as to obtain a heat-stable vinyl chloride composition. A cable covered with the polyvinyl chloride family resin composition is also disclosed, including a cable having electric wires coated with the polyvinyl chloride family resin composition.
