Product Description

The DMC catalyst is double metal cyanide catalyst. Compared with similar polyols made using basic(e.g.,KOH)catalysts, polyether polyols made from the catalyst have low unsaturations, narrow molecular weight distributions, can have high molecular weight ,and are useful in making a variety of polyurethane products.  DMC catalyst is highly active in epoxide polymerization reactions used to prepare polyether polyols. We can yield the DMC more than 20000kg within one year, and thus afford to produce 50-70 ten thousand tons of polyols. This catalyst is white or light yellow powder, is suitable for preparation of polyols with 1~6 functions. Compared with basic catalysts, this catalyst can be used with less amount (30ppm),and reaction time of polymerization is reduced largely, and the polyols products are not necessary to be refined. The DMC is suitable for using in common epoxide polymerization reactors, but it can be better if reactors have both of stirring and cycling systems.
When using the DMC production period is short, thus the costs for production are reduced while the property of products are advanced.

Frequently Asked Questions

Q1: May I get one sample before placing order?
Re: Yes, Sample are available. For normal products, samples are for free and you just need to bear the freight; 

For those high value products, you just need to freight and certain product cost. When we both cooperate for 

some times or when you are our VIP customer, free sample will be offered when you need.

Q2: Which payment is available for your company?
Re: T/T, L/C. You can choose the one which is convenient for you. 

Q3: How and when can I get my goods after payment?
Re: For small quantity products, they will be delivered to you by international courier(DHL, FedEx, TNT etc.) 

or by air. Usually it will cost 3-5days that you can get the goods after delivery.For large quantity products,

shipping by see is worthwhile.It will cost days to weeks to come to your destination port, which depends on 

where the port is.

Q4: Is there any possible to use my appointed label or package?
Re: Yes. If needed, we'd like to use label or package according to your requirement. 

Q5: How can you guarantee the goods you offer is qualified? 
Re: We always believe honesty and responsibility are basis of one company, so whatever products we provide 

for you all are qualified. We will have goods tested and provide COA before delivery for sure.
