宇部 聚碳酸酯二醇 UM-90(1/3) UM-90(1/1) UM-90(3/1) UC
ETERNACOLL® UM 和 UC 分别是 UBE 公司生产的环状聚碳酸酯二醇和共聚碳酸酯二醇的商标名称，其中使用了两种不同的二醇作为二醇成分。这些无溶剂等级适用于不同的聚氨酯配方，能为最终聚合物提供高硬度和出色的抗刮擦性能。
ETERNACOLL® UM 和 UC 适用于那些对最终聚合物的高性能和耐久性有要求的场合，即在热、水解、化学和耐候性方面要优于脂肪族聚碳酸酯二醇。
UBE 已开发出一种生产技术，能够生产出具有不同物理特性的四种等级的“ETERNACOLL® UM”和“ETERNACOLL® UC”产品，这些产品已投入商业使用，可适应任何生产流程，并能实现预期的性能指标，同时具有更高的耐用性。
ETERNACOLL® UM 和 UC 的优势
由聚碳酸酯二醇制成的聚氨酯
ETERNACOLL® UM 和 UC 比基于聚醚二醇和聚酯二醇基型的产品更具优势，它们具备以下特性：
出色的硬度
出色的水解稳定性
出色的耐化学性
出色的热稳定性
出色的抗划痕能力
此外，所有经过各种添加剂处理的产品均显示出与聚碳酸酯二醇的最佳兼容性。

ETERNACOLL® UM and UC are the brand name of UBE for cyclic
polycabonate diols and copolycarbonatediols, respectively, where two kind
of diols are used as diol component. Solvent free grades used for different
PU formulations providing high hardness and excellent scratch resistance to
the final polymer .
ETERNACOLL® UM and UC is recommended for those applications when
high performance and durability to the final polymer is requested in terms
of the excellent heat, hydrolytic, chemical and weathering resistance than
aliphatic polycarbonatediols
UBE has developed a production technology for producing four grades of
ETERNACOLL® UM and UC with different physical properties, commercially
available, for being adapted to any production process and meeting desired
target properties with improved durability.
Benefits of ETERNACOLL® UM and UC
Polyurethanes produced from
polycarbonate diols
ETERNACOLL® UM and UC are superior to those based on
polyether diol and polyester diol countertypes, providing:
Excellent hardness
Excellent hydrolytic stability
Excellent chemical resistance
Excellent thermal stability
Excellent scratch resistance
Moreover, all tested with various additives agents have
shown optimum compatibility with polycarbonatediols
ETERNACOLL® UM and UC formulations.
