Product description :

Hydroxy propyl Methyl cellulose -HPMC

 Hydroxy propyl methy celluse is a type of nonionic cellulose erher made from natual high molecular material through a series of chemical processes.With almost all properties of methyl cellulose ,it is the auxiliary agent of first choice in the production of top-quality construction materials.To satisfy the requirement of envirment protection,Tasong brand product is developed and produced particularly for the construction material industry .With such favourable features as high water retention,good dispersancy,high degree of fineness ,niss placeability and convenience to dissolve ,it is applicable to the production of innovative construction materials like dry-powder mortar,waterproof putty powder(paste) for indoor and outdoor walls,binding agent,gap filler,interface finishing agent ,water paint,self-leveling agent ,etc. In the production of construction materials,cellulose ether is an indispensable additive.After HPMC is added the following properties can be enhanced

Main application:

HPMC may act serve as thickening agent ,dispersant agent ,emulsifying agent or film -forming agent ,and its industralized products may be applicable to the production of daily chemicals ,synthetic ,construction and coating materials.

1.Suspension polymerization

In the production of synthetic resin such as polyvinyl chloride (PVC) ,polyvinytlidene chloride(PVDC) and other copolymerisate,suspension polymerization is the most used and it requires to keep hydrophobic monomers to suspend in the water .HPMC product has excellent surface activity as a type of water-soluble polymer,In addition,it plays the role of collidal protectant that is can delay the coacervation of particles.,Furthmore ,alghough HPMC is a type of water-soluble polymer,it is somewhat dissolvable in hydrophobic monomers and can enhance the monomer porosity for production of polymerizing particles,thus ,it may tender polymer good capacity or removal of residual monomers and absorption of plasticizer.

2.It is applicable to the production of following products in the recipe of construction materials

1)Waterproof putty powder

2)Cement and mortar

3)Cement base brick/tile and the bonding between tile and base brick

4)Plaster for gypsum board base

5)Cement-based structual plaster.
