Professional R&D and excellent quality plasticizer chemicals

Cold-resisting plasticizer DOA and DOS are common. Main difference is cold-resisting level. DOA use into PVC soft products,cold-resisting level from 0 to -25 degree. DOS use into PVC soft products,cold-resisting level from -26 to -39 degree. PVC products cold-resisting limit is - 39 degrees Celsius. Need to do modification if lower.

This classification defines 20 viscosity grades in the range of 2 to 3200 square millimeters per second (1 mm2/s = equals 1 cSt) at 40C (104F). For petroleum-based liquids, this covers approximately the range from kerosene to cylinder oils. Each viscosity grade is designated by the nearest whole number to its midpoint kinematic viscosity in

There are four different propylene glycol. At ChemWorld, we provide different grades of Propylene Glycol. Here is a breakdown of each one: Propylene Glycol - 99.9% Pure internally repackaged certified USP grade that is packaged in containers starting at 2 oz to 5 Gallons . When to Use?

3) Denatured Ethanol. Denatured ethanol (either 95% or absolute) contains additives (such as methanol and isopropanol) that render it unsafe to drink and therefore exempt from certain beverage taxes. This makes it cheaper than pure ethanol. Of all the ethanol grades, this is the one you’re most likely to use for disinfection in your lab.

Industrial Grade products have off the shelf extended temperature ratings of -45C to 90C. In addition, they can be screen tested to much higher and lower temperatures. Commercial Grade products are typically rated at only 0C to 70C or in many cases not rated.
