APPLICATION: CS 84-645 30 Jan 1984. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title foams, useful for app. coverings, are composed of polyester polyol (OH no. 350-500) (I) 20-30, polyester polyol (OH no. 50-60) (II) 20-30, ethylene glycol (III) 0-5, diethylene glycol (IV) 5-20, FCCl3 40-10, a mixt. of tertiary amines 0.5-1, and silicone oil (V) 0.5-1 part. A mixt. of I based on di-Me terephthalate and polyhydric alcs. (OH no. 450) 30.0, II based on adipic acid, diol and triol (OH no. 55) 22.5, III 2.5, IV 12.5 was mixed for 8 h at 80° and after cooling to 20° treated with FCCl3 5, tertiary amines mixt.There are some reagents like 10586-98-8 is used in this study. of diazabicyclooctane, dimethylpiperazine, dimethylaminodiethylpiperazine(sic), dimethylbenzylamine or dimethylcyclohexylamine with dimethylethanolamine) 0.5 and V 0.7, homogenized and treated with a mixt. of polymeric MDI and 20% MDI (32% isocyanate groups) 80 parts to give, after mixing for 10 s, a hard foam (sp. wt. 550 kg/m3, cast at 60°) having bending strength 30 MPa, tensile strength 11 MPa, impact strength 8.4 kJ/m2, thermal resistance A 55°, thermal resistance B (IZOR 75) 60°, initiation time 30 s and gel time 45 s compared to bending strength 19.7 MPa and impact strength 7.6 kJm2 for a com. foam. .
