Hydroxypropyl beta-cyclodextrin are purified polydisperse products resulting from the controlled reaction of propylene oxide and native beta-cyclodextrin. Hydroxypropyl beta-cyclodextrin is itself very soluble in water (greater than 500 mg/ml at room temperature compared to 18 mg/ml for beta-cyclodextrin), and is used for molecular encapsulation of a variety of sparingly water compounds to enhance the aqueous solubility of the encapsulated compound.

Mild steel, sometimes referred to as carbon steel or ordinary carbon steel, is defined as having a carbon content of no more than 2% and no other perceptible alloy elements.
This steel is produced on a large scale and is the largest part of the steel production industry. You will be able to find it in various applications, fasteners and fasteners.
Generally, this kind of steel has high strength, high hardness and magnetism, and is usually used in motors and electrical appliances - however, their corrosion resistance is poor, and should not be used in corrosive environment without protective coating or coating.
There are some differences between low-carbon steel and steel, because steel has lower toughness and greater brittleness, and low-carbon steel can be further strengthened by adding carbon.
If you need more information or want to order carbon steel products, such as hexagon Bolts, carriage bolts, flange bolts, U-bolts, union bolts, expansion bolts, threaded rods, please contact us.
