Product Introduction:

Polyacrylic acid (PAA), also known as acrylic resin or acrylic homopolymer, is a water-soluble polymer with the chemical formula [C3H4O2]n, which is weakly acidic.

Polyacrylic acid has outstanding features such as very easy coloring, lightweight, hard to break, as well as excellent processing efficiency. It is usually used as a substitute for glass, optical lenses, lenses, and so on.

It can develop steady substances with steel ions, calcium, magnesium, and so on, and also has exceptional disintegration impact on calcium carbonate and calcium hydroxide in water.

Furthermore, with the advancement of acrylic materials as well as their modified polymers, acrylic resins are likewise widely used in pharmaceutical prep work and also finishes.

Polyacrylic acid is created by polymerizing acrylic monomers in aqueous option with persulfate as initiator.

The typically utilized synthesis approaches of polyacrylic acid consist of four polymerization approaches: anionic polymerization, remedy polymerization, mass polymerization and suspension polymerization.

Product Usage:

The use of polyacrylic acid can be divided according to the molecular weight. The molecular weight is between 10,000 and 1,000,000. It mainly plays a dispersing role and can be used in coating, papermaking, printing and other industries.

  • Molecular weight between 5000-10000, mainly for thickening. Polyacrylic acid thickener has fast thickening speed, fast efficiency and good biological stability, but it is sensitive to pH value, poor water resistance, low gloss and other shortcomings. , can be used as acidifying solution, thickener for cosmetics.
  • The molecular weight between 1 million and 10 million can be used for flocculation. Polyacrylic acid can be used for the treatment of industrial wastewater, the separation of electrolytic salt water and red mud.
  • With a molecular weight greater than 10 million, polyacrylic acid is no longer soluble in water, and it is easy to form a gel in water, forming a hydrogel to absorb water. It can be used as a water absorbing agent for cement water reduction, cement drilling dewatering, etc.

Practical Application of Polyacrylic Acid in the Industry:

In regards to pharmaceutical prep work:

  • Since Polyacrylic Acid is risk-free, stable, non-irritating and also inert, it is a polymer material extensively made use of in pharmaceutical preparations.
  • Poly( acrylic acid) can be split into 2 groups: methacrylic acid copolymer as well as methacrylic acid ester copolymer. Due to the various copolymer components as well as percentages, it has various homes of being soluble in stomach juice as well as digestive juice or insoluble in water.
  • It is frequently utilized in film covering, strong dispersion, sustained-release pellets, sustained-release matrix tablet computers and various other pharmaceutical objectives.
  • Furthermore, acrylic resin has far better efficiency as a pharmaceutical excipient and has a wide room for growth.

Coating:

  • Polyacrylic Acid has light color, excellent openness and also superb gloss and also color retention. High temperature does not decompose and does not transform color, has good acid as well as alkali resistance, salt, oil, cleaning agent and various other chemicals contamination and also rust efficiency, and also exceptional building performance.
  • Specifically, it can be thoroughly customized with different chemical monomers and also brand-new materials to impart various unique homes to prepare brand-new varieties of acrylic resin layers.
