Audited Supplier HPMC. Hydroxypropyl methylcellulose, a high-purity green material, and refined cotton as raw material. The white powder obtained through a series of chemical processes is often used as an additive in many industries.
HPMC cellulose hydroxypropyl methyl ether is made of highly pure cotton cellulose as raw material, treated with lye at 35-40ºC for half an hour, pressed, crushed the cellulose, and properly aged at 35ºC to make the obtained The average degree of polymerization of the alkali fibers is within the desired range.
Put the alkali fiber into the etherification kettle, and etherify at 50-80ºC for 5h, the maximum pressure is about 1.8MPa. Then wash the materials in hot water at 90°C to increase the volume, and then dewater them in a centrifuge, and finally wash them repeatedly to neutrality.

About Asphalt Adhesive:
Asphalt is divided into two categories: natural asphalt and petroleum asphalt, and petroleum asphalt is mainly used as an adhesive.
There are three types of adhesives formulated with asphalt: hot-melt type, solvent type and emulsion type.
Asphalt is inexpensive, has excellent water resistance and alkali resistance, and has good durability. It is widely used in civil construction, especially in the construction of roads, bridges and houses.
But the oil resistance and solvent type are poor, and heating has the disadvantage of softening tendency.
