Could you recommend some chemical products or raw materials (liquids) with high viscosity, preferably with a viscosity of over 10 MPa·s? Such as sulfuric acid, nitric acid, etc. Thank you all~~~~~
A viscosity of 10 mPa·s isn’t considered high, is it? The viscosity of concentrated phosphoric acid is higher than that in the example given by the original poster. Other substances such as heavy diesel, heavy oil, and glycerin are also materials with high viscosity. There are also some with very high viscosity, such as polyethers and polyaminols; the solution viscosity of these polymers can sometimes be so high that they are almost immobile.
Reply to 2# qugd: Thank you. What I need are common chemical liquids. The liquid viscosities found in property manuals are mostly below 1. There are few between 10 and 100.
What I mentioned are all liquids used in the chemical industry, including both inorganic and organic ones, as well as polymers. It’s quite comprehensive.
Yes, those with a value of over 100 mPa·s are included
The relationship between viscosity and temperature is very close. For example, coal tar has a viscosity of around 20 cp at 80 degrees, while it may drop to 1 cp at 200 degrees. Asphalt with a temperature below 200 degrees also has high viscosity.

We encountered a highly viscous mixed polymer with a viscosity as high as 40,000 cp, which can only be measured using an OVAL helical gear flow meter. The OVAL super-elliptical gear flow meter can measure media with a flow rate of up to 500,000 cp. http://shakic.com/cp/OVAL%20Ultra%20oval%20gear%20flowmeter.htm For high-viscosity flow measurement, oval gear flowmeters are recommended: http://www.shakic.com/cp/OVAL%20LG%20oval%20gear%20flowmeter.htm http://www.shakic.com/cp/OVAL%20...ear%20flowmeter.htm
