Chemtex is involved in the manufacturing of a wide range of Polyacrylic acid of low and high molecular weight and compositions of mono (homo-polymer), bi (copolymer), terpolymer etc. Different formulations have different role in various applications depending on the type of role the particular application desires.

Polyacrylic acid or Polyacrylates are also available in solutions and salts. This Polyacrylic acid finds wide usage as a thickening and emulsifying agent in many industries such as cosmetics, pharmaceuticals and paints. Polyacrylic acid and its derivatives are used in ion exchange processes. In a water solution at neutral pH, PAA acts as an anionic polymer, i.e. many of the side chains of Polyacrylic acid will lose their protons and acquire a negative charge.

Chemtex Speciality Limited has been in this field of manufacturing industrial chemicals for the past 45 years and they are involved in the production of a varied range of polymers finding application in various fields. Polymer gels are comprised of cross-linked polymer network inflated with a solvent such as water. They exhibit the ability to reversibly swell or shrink due to small changes in their environment.

Micro sized gel fibers contract in milliseconds, while thick polymer layers require minutes to react. The most common Polymer Gels are poly vinyl alcohol (PVA), polyacrylicacid (PAA) and polyacrylonitrile (PAN), etc.

Chemtex Speciality Limited manufactures a wide range of industrial chemicals that in turn help in the smooth running of other industrial operations. Chemtex has been involved in manufacturing a variety of chelants and sequestrants for the past 45 years, among which polyphosphates have gained much appreciation from our clients worldwide.

Polyphosphates serves as salts or esters of polymeric oxyanions formed from tetrahedral PO4 (phosphate) structural units linked together by sharing oxygen atoms.Polyphosphates arise by polymerization of phosphoric acid derivatives. The process begins with two phosphate units coming together in a condensation reaction.Polyphosphates function as water purification chemicals that are employed to rectify problems caused by inorganic groundwater contaminants such as iron, manganese, calcium, etc. and also for the preservation of water quality in distribution systems.Polyphosphates are well known for their function in the living organism but they find their application as a chelant or sequestrant in waste water treatment.

Key Features and Benefits:

• Polyphosphates react with soluble metals by sequestering the metals for maintaining their solubility in water
• Polyphosphates were one of the first chemicals used as corrosion inhibitors
• Polyphosphate has the added advantage of being a scale inhibitor apart from being a sequestering agent

Chemtex Speciality Limited manufactured product Sodium Polyacrylate can be referred to as a sodium salt of polyacrylic acid. It is also known as water lock. Sodium Polyacrylate functions as an anionic Polyelectrolyte having negatively charged carboxylic groups in the main chain. While polyacrylic acids neutralized with sodium are still the most common form used in industry, but other salts also exist including potassium, lithium and ammonium.

Sodium Polyacrylate is used as a sequestering agent in detergents which portrays its ability to bind hard-water elements, such as magnesium, iron, calcium and zinc, to make the detergents work more efficiently. Chelating agents help to neutralize the presence of heavy metals that are available in water, dirt and other substances found in laundry, making the detergent more effective in cleaning and neutralizing odors in clothes. It also functions as thickening agents or as super absorbent polymers. Sodium Polyacrylate also serves as the main ingredient in high-absorbency diapers.


Key Features and Benefits

• Works as an effective sequestrant
• Can function as super absorbent polymers

Super Absorbent polymers or SAP, also known as water absorbent polymer, manifests as polyacrylate based polymers that is characterized with the capacity of absorbing upto 800 times of DM water of its own weight. The ability of the Super Absorbent Polymer to absorb water is directed by the ionic concentration of the aqueous solution. SAP can be used in various applications such as in baby diapers, adult protective underwear and sanitary napkins, composites and laminates, candles, diapers and incontinence garments, insecticides and herbicides, Fire-retardant gel, Hot & cold therapy pack, Water retention for supplying water to plants, Artificial Snow etc. The total capacity of absorbence and capacity of swelling are maintained by the type and degree of cross-linkers which are formulated into the gel. SAP has a softer and sticker gel formulation. Super Absorbent Polymer is also used for blocking water penetration in underground power or communications cable, control of spill and waste aqueous fluid, horticultural water retention agents, and artificial snow for motion picture and stage production.

The Dispersing Chemicals are superiorly used for preventing system from fouling caused by the biological gathering of slimes, algae and bacterial deposits. On continuous usage of cooling towers, biofilms get generated on the surface due to microorganisms that can be eliminated by using these dispersing chemicals, which then is specifically called biodispersing chemicals. Our formulations are superlatively known for its features like improvise the efficacy of other biocides, compatible with all biocides and reduce the volume of micro biocides to be dosed.

The chemical formulations offered by us are excellent in putting off Microbiologically Induced Corrosion (MIC). These chemicals are suitable to be utilized in air washers, evaporative condensers, cooling water heat exchangers, blow moulding machines, D.G. sets and various other machines.

Water soluble polymers is a unique formulation of Chemtex Speciality Ltd, used in various applications of water treatment such as in coagulation, flocculation and dispersion applications. The total absorbing and swelling capacity of the polymer is controlled by the type and degree of cross-links used to make the gel. Water soluble polymers, which are considered as hydrogels when cross-linked, absorb aqueous solutions with the help of hydrogen bonding with water molecules. Low-density cross-linked Water soluble polymer generally has a higher absorbent capacity and swells to a larger degree.Chemtex Speciality Limited is an ISO 9001, ISO 14001 and OHSAS 18001 certified company that specializes in the manufacturing of water soluble polymers.
