Polymers & Phosphonates

Amino Trimethylene Phosphonic Acid (ATMP) is a phosphonate that finds its biggest application in water treatment. ATMP are available in salts of sodium compounds such as ATMP 2Na (Amino Trimethyl Phosphonic Acid - Disodium salt), ATMP 4Na (Amino Trimethyl Phosphonic Acid - Tetra sodium salt) etc. The product is commercially produced in liquid form as ATMP 50%. 

Amino Trimethylene Phosphonic Acid (ATMP), provided by Chemtex Speciality Limited, consists of properties such as low threshold inhibition, lattice distortion, and exceptional chelation. This acid helps in the prevention of formation of calcium carbonate in water system. It exhibits excellent chemical stability, best corrosion inhibition and is difficult to hydrolyze in water systems. ATMP can be used in oilfield water pipeline in thermal power plant & oil refinery and in industry for circulating cool water system.

Key Features and Benefits:

• Effectively used as a scale inhibitor in water treatment
• These also serve as an effective substance in detergent and cleaning applications
• It exhibits excellent chemical stability

HEDP or Hydroxyethylidene Diphosphonic Acid serves as an organo phosphonate compound having multifunctional properties such as deflocculation, sequestration, and super threshold inhibition as a single active ingredient. HEDP are available in salts of sodium compounds such as HEDP 2Na (Hydroxyethylidene Diphosphonic Acid - Disodium salt), HEDP 4Na (Hydroxyethylidene Diphosphonic Acid - Tetra sodium salt) etc. The product is commercially produced as HEDP 50% / 60% in liquid form.

It serves as a scale and synergistic corrosion inhibitor for inhibiting iron rust and mineral scale in pipes of cooling circulation water units and boilers. It also acts as a metal chelate agent for colour fixing and bleaching in textile and also functions as a complexing agent for electron plate and scale cleaning agent for metals.

Key Features and Benefits:

• Acts as a metal chelate agent
• Helps as an effective scale inhibitor

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 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

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.

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. It has also established itself to be among world's renowned multipurpose chemical exporter having its facility in India. Chemtex's greatest business vitality and strength are its technical and manufacturing knowledge and a well developed technical service team. 

Key Features and Benefits:

• Multi functional
• Cost effective
• Used as dispersants
• High absorbent capacity
