介绍Arcol PPG-4000 polyol is a 4,000-molecular-weight diol based on propylene oxide. Arcol PPG-4000 polyol is a high-performance, low-monol polyether that is prepared with Bayer 's proprietary IMPACT® technology, using a patented organo-metallic propoxylation catalyst. The terminal end-groups are predominantly secondary hydroxyls and have a relatively low reactivity. This polyol is acidified with a low level of phosphoric acid, making it suitable for use in isocyanate-terminated prepolymers.

Arcol PPG-4000 polyol is used in polyurethane and other applications, including cast elastomers, sealants, epoxy flexibilizers, defoamers, lubricants, crude oil de-emulsifiers and plasticizers. Arcol PPG-4000 polyol is a complementary product to Acclaim 6300 polyol, an ultra-low monol triol with the same equivalent weight. Overall polyol functionality can easily be varied by blending these two polyols.

This polyol contains extremely low levels of monol. In some polyurethane systems, formulation changes, such as reducing the crosslinking level or changing the hard-segment content, may be necessary to maximize the benefits of using Acclaim polyols. As with any product, use of Arcol PPG-4000 polyol in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
