Fuel and hydrolysis resistant polyurethane. |
摘要 |
<p>A polyester polyurethane compound is formed by reacting trans-1,4-cyclohexanediisocyanate with a mixed polyester. The mixed polyester can be the copolymerization condensation product of an aliphatic dicarboxylic acid or an aromatic dicarboxylic acid, or a separate physical blend thereof reacted with a polyol. The polyurethane can also contain small amounts of non-extractable epoxies and carbodiimides. The urethane has very good hydrolytic stability in comparison with prior art polyurethane systems and also very good fuel resistance and anti-icing resistance. A preferred area of use is as aircraft fuel tanks and anti-icing components.</p> |
