摘要:
A flame resistant synthetic fiber having advanced flame resistance is provided. Furthermore, the flame resistant synthetic fiber may preferably be used in textiles used for furniture, such as beddings and chairs, such as mattress, and sofa, etc. that need extremely high carbonizability rendered highly flame resistant by flame resistant agents and advanced flame resistance. The present invention also aims at obtaining upholstered furniture products using the flame resistant fiber composite having advanced flame resistance. That is, the present invention relates to a flame resistant fiber composite consisting of a flame resistant synthetic fiber (A) not less than 10 parts by weight, and at least one fiber (B) selected from a natural fiber and/or a chemical fiber (B) not more than 90 parts by weight, the flame resistant synthetic fiber (A) comprising 100 parts by weight of a polymer containing halogen atom of not less than 17% by weight, 3 to 50 parts by weight of a zinc compound, 0 to 30 parts by weight of an antimony compound, and 3 to 30 parts by weight of an other inorganic compound, a total amount of these compounds being not less than 15 parts by weight, and also relates to upholstered furniture products using the flame resistant fiber composite.

A preferable optical material which has a stable structure containing ions of a rare earth metal and retains transparency in the visible light to the near infrared regions. The optical material is obtained by curing a fluororesin composition comprising (I) a fluoroprepolymer and (II) ions of a rare earth metal and/or a compound containing a rare earth metal element, the fluoroprepolymer (I) containing a curable fluoropolymer which (1) is an amorphous polymer having a fluorine content of 25% or higher and (2) has a curable part in a side chain of the polymer and/or at an end of the polymer backbone.
摘要:
An ultraviolet-crosslinkable polymer composition comprising a polymer containing iodine and/or bromine in an amount of from 0.001 to 10 % by weight, a photoinitiator as a crosslinking agent and a polyfunctional unsaturated compound as a crosslinking aid. By using iodine and/or bromine as a crosslinking point, it is possible to carry out crosslinking of various polymers including fluorine-containing polymers which have been very difficult to crosslink with ultraviolet rays, and molding or processing can be made easily at working site at low temperature.

摘要:
A process of reducing the effects of moisture during storage prior to vulcanization of a vulcanizable halogen-containing polymer composition containing water, comprising blending before storage, into said vulcanizable composition, a thioester derivative of 2,5-dimercapto-1,3,4-thiadiazole crosslinking agent and glycerin, whereby the scorch time of the vulcanizable compound is not significantly affected by the water content of said composition. In addition, a vulcanizable halogen-containing polymer composition comprising a thioester derivative of the crosslinking agent and glycerin, and a dry pourable powder cure premix composition comprising the crosslinking agent, glycerin and a pourable siliceous finely divided filler.
摘要:
Curable silicone compositions comprise either (a) microparticles of a fluororesin, which exhibits low adhesion to the cured composition, or (b) microparticles of an organic or inorganic material whose surfaces have been coated with this type of fluororesin. The compositions are useful coatings for semiconductor devices requiring high levels of moisture- and heat-resistance.
