Description
車両製造業者は、車両のボンネット下に使用されるポリウレタン製品について、UL−94 V−2等級(すなわち、Underwriters Laboratoriesによって定義されるところの、材料が垂直にした試験片において30秒以内に燃焼停止することを示し、火炎粒子の滴下が認められ得る燃焼性等級規格)を要求することから遠ざかっている。この点に関して、車両製造業者は、目下、新車両における使用のために、UL−94 V−0等級(すなわち、Underwriters Laboratoriesによって定義されるところの、材料が垂直にした試験片において10秒以内に燃焼停止することを示し、非火炎粒子の滴下のみが認められる燃焼性等級規格)を有するポリウレタン製品を求めている。したがって、UL−94 V−0燃焼性等級要件を満たす可撓性ポリウレタン製品が求められる。
R1及びR2は独立して、H、1〜12個の炭素原子を有する直鎖、分枝鎖、または環状アルキルであり得る。ビウレット変性MDIは、20重量%超のMDIの2,4′異性体、及び20重量%超のMDIの2,2′異性体を含み得る(例えば、50重量%のMDIの2,4′異性体及び50重量%の2,2′異性体を含み得る)。
ポリオール成分においては、
本発明は、以下の態様を含む。
