Hydroxyethyl Cellulose(HEC)
CAS NO.:********0
1.Properties :
1).It is a white or yellowish powder which is odorless,
tasteless, easy for flow. It can dissolve in hot water, but also
cold water, can’t easily dissolve in organic solvent, In general,
almost organic solutions, dissolve in the scale of pH ***2, their
viscosity change is seldom.But once over this scale, their
viscosity will reduce.Through surface treatment, in cold water, HEC
will disperse, but not coagula, but its solution speed is slower.
Generally need about *3min. Heat it or adjust pH value to ***0, it
will rapidly dissolve
2).With non-ionic characteristic it can coexist with other
water-soluble polymer, surfactant, salt in a wide range. It is a
fine colloidal thickener for high concentration electrolyte
solution; its water retention capacity is twice than methyl
cellulose, and has good flow adjustability.

3.Applications :
As a non-ionic surfactant, with thickening,bonding,
suspension, adhesion, floating, film-forming, dispersing, water
retention and protecting colloid properties,so it is widely used in
the polymerization and copolymerization of synthetic resin,
synthesizing of latex, preparation of water-based latex paint,
preparation and synthesizing of binder, fabric processing, oil
drilling, construction & building materials, daily chemical
products , paper making, coating,ink chemical and so on..
4.Package, transport, storage
This
product adopts coating plastic polypropylene woven bag inter lining
polypropylene to packaging. Every bag’s net weight is *5Kg. it
should store in room which is ventilate, dry, notice damp proof.
When transporting, pay much attention to the rain, sunshine.
