Compound 12+90=102 1 carbon atom 0 hydrogen atoms 2 fluorine atoms 2*1+2=4 bonds therefore 2 chlorine atom Dichlorodifluoromethane. Excellent compatibility with acrylic, polyester, epoxy resins. Polyol R6405, which meets the EU polymer definition, is a chemical building block and is used to make acrylic esters and cross-linkers. However, some Dow polyols require that chemical workers’ goggles be worn. Chemical Resistance Guide. }, abstractNote = {For the past 10 years polyurethane polymers have been one of the fastest growing segments of the plastics industry. In addition, the polyol needs to be compatible and stable with wa-ter and other additives in the resin blend. CHEMICAL STRUCTURE Chemical structure Elastollan® Elastollan® is essentially formed from the inter-reaction of three components: 1. VORANOL 800. It has high activity and offers good demolding. Introduction to Polyether Polyols Main Application Area for IMPACT™ Technology is Polyether Polyols for Polyurethanes. The remaining ingredients in the “B” side serve different purposes to help control the creation of the foam bubbles (the “cells”) in an optimal way, and to provide the various characteristics of the finished foam product (flame retardancy, for example). requirement. The high sucrose content with the high hydroxyl number has excellent compatibility with blowing agents and isocyanates for appliance, high density and general-purpose foam formulations. Preferably, a polyol of the present invention is substantially derived from butylene oxide if it includes at least about 50 percent, more preferably at least about 70 percent, and most preferably at least about 80 percent by weight of the polyol is derived from butylene oxide. The free monomers can have a significant effect on the efficacy of the polyol in the final foam product. Two-component (2K) polyurethane (PU) coatings are widely used in automotive interior and electronic device applications because of their high durability and excellent tactual sense characteristics. Aliphatic Polyester Polyols Many aliphatic polyester polyols have been prepared and at one time or another been offered on the market. The solubility of Opteon™ 1100 in polyester polyols is generally lower, ranging from 5 to 30 weight % at room temperature. CFC-12 and R-500 chillers to Freon™ 134a and has replaced its other CFC-12 and R-500 chillers with new chillers operating on HCFC-123, Freon™ 134a, or HCFC-22. 7% OH, that when combined with appropriate aliphatic polyisocyanates, provides rapid ambient curing properties, good through hardening excellent durability, good chemical resistance, and outstanding gloss retention. 2132, Page 1 15th International Refrigeration and Air Conditioning Conference at Purdue, July 14-17, 2014 Material Compatibility of HVAC&R System Materials with Low GWP Refrigerants Julie A.
