摘要:
The present invention pertains to polyols having autocatalytic properties in urethane formation. Such polyols are prepared by end-capping polyols with a tertiary amine. The invention also discloses the process for producing such polyols an their use in production of polyurethane products.
摘要:
The present invention pertains to low emission polyurethane polymer products based on autocatalytic polyols made by modification of conventional polyols with tertiary amines and processes for their manufacture. The tertiary amine is bound to a conventional polyol by means of an epoxide, epichlorohydrin, or grafting by means of an azo and/or peroxide initiator or sulfonyl azide.
摘要:
The present invention pertains to low emission polyurethane products based on autocatalytic polymers made by reaction of epoxide resins with compounds containing secondary and/or tertiary amines bearing a reactive hydrogen and to processes for their manufacture.
摘要:
The present invention pertains to non-fugitive amine catalysts wherein the catalyst contains at least one imine and at least one tertiary amine moiety. Such catalysts are suitable for the production of polyurethane products.
摘要:
The present invention pertains to acid blocked, amine-based, autocatalytic polyols, and to the use of these autocatalytic polyols in the production of polyurethane foams having superior aging characteristics.
摘要:
The present invention pertains to fusible catalysts, to processes for their manufactures and to their use in the production of low emission Polyurethane products.
摘要:
The present invention pertains to a copolymer polyols based on tertiary amine based polyols and to polyurethane products made therefrom. The use oof such copolymer polyols reduces the amount of amine catalysts needed for the production of polyurethane foam.
摘要:
The present invention discloses a process for producing a polyurethane product with autocatalytic polyols. These autocatalytic polyols are based on an initiator that contains a tertiary amine. These autocatalytic polyols are reacted with a polyisocyanate in the presence of other additives and/or auxiliary agents known per se to produce polyurethane products.
摘要:
The present invention employs a privacy mask, with elongated mouth-piece, having a semi-circular opening for a user's mouth and a second opening coupled with a transfer tube in which a user's voice travels until it reaches the receiver of a mobile phone or computer, inserted in a head-set equipped with ear-pieces. The present invention is a telecommunication device allowing both speaking and listening with privacy, since it prevents both the user's voice to spread in the surrounding and outside noises to disturb the communication.
