DMC catalyst is a new type of high-performance catalytic olefin oxide ring-opening polymerization catalyst, suitable for synthesis of olefin oxide polyether containing 1-6 functional groups. DMC catalyst manufacturers usually use low molecular weight organic complexing agents. The complexing agents beneficially affect the activity of the catalyst for epoxide polymerization.
The production of polyether with DMC catalyst has the following advantages:
Low production and running costs
1) No post-processing process and faster reaction speed increase the production capacity of the device by several times.
2) No post-treatment process reduces equipment investment, unit product energy consumption and water consumption, unit product solid waste and waste water production, and improves product yield.
3) It can produce higher molecular weight products with molecular weight of more than 2000 per mole of hydroxyl group.
4) The produced polyether has the characteristics of narrow molecular weight distribution, few by-products, low unsaturation and low odor. When it is used in the PU field (elastomers, soft foams, high resilience foams, coatings, sealants), various aspects of properties such as tensile, elongation, and compression are greatly improved.
