Caprolactone Polyols 己内酯多元醇

Unique aliphatic polyester polyols

Made via ring opening polymerisation – no by-products

This gives a tighter manufacturing specification than most other polyols

Very low acid values with premium grades having a negligible acid content

Controlled poly-dispersity

Relevant molecular weight ranges and functionalities for any PU system

独特的脂肪族聚酯多元醇

通过开环聚合反应 - 没有产生副产品

与其他多元醇相比，它的制造规格更严竣。

高等级的CapaTM系列产品的酸含量非常低。

可控制聚分散。

适当的分子量和官能度可供予任何聚氨酯系统的应用。
