General description

Poly (acrylic acid) (PAA) is hygroscopic, brittle and colorless in nature with Tg at nearly 106oC. At temperatures above 200 to 250oC, it loses water and becomes an insoluble crosslinked polymer anhydride. Solubility of dried PAA in water increases with rise in temperatures. Concentrated solutions of PAA in water is thixotropic in nature.

Application

  • to study solute diffusion in Polyvinyl alcohol/PAA copolymer hydrogel
  • synthesizing poly(N-isopropylacrylamide)-block-PAA copolymer which responds to both temperature and pH stimuli
  • in preparing block copolymer of oligo (methyl methacrylate)/PAA for micellar delivery of hydrophobic drugs
  • as thickening agent for adhesives.

Product Usage:
Antiseptic has a very strong broad spectrum antibacterial, bactericidal effect, have the ability to kill gram-positive bacteria and Gram-negative bacteria . Widely used for skin disinfection, surgical disinfection, instrument disinfection irrigation wound, bladder irrigation burns, burns, can also be used for oral anti-inflammatory, truscutis and abdominal cavity and intestinal mucosa disinfection in surgery, also used for daily tableware, vegetables and fruits, drinking water disinfection. Chlorhexidine gluconate aqueous solution is often prepared clinically for various purposes of disinfection.

 

 

 

Application Cases:

 

 

Application METHOD:
Chlorhexidine gluconate is often used as a formula with other disinfection agents. The specific formula and usage and dosage should be determined according to the experimental results of the equipment.  2% aqueous solution is recommended for use as a disinfectant

 

Storage:
Store in a cool, ventilated warehouse. Avoid light . The temperature of the warehouse should not exceed 37℃. It should be stored separately from oxidants and edible chemicals. Do not mix storage to keep the container sealed. Keep away from fire and heat. Lightning protection equipment must be installed in the warehouse.

 

Authoritative test report:
Through the third party authority testing , quality can be guaranteed
