Polyacrylate based Super Absorbent Polymer – Its Application & Usage

 

Recently, materials science has made significant advances, with numerous applications across various industries. One such innovation that has gained enormous attention is polyacrylate-based superabsorbent polymers. They are extraordinary substances that possess the remarkable capacity to absorb and retain large quantities of liquids, which can prove vital in a variety of different sectors, right from personal care products, agriculture to medical applications and beyond.

Polyacrylate based Super Absorbent Polymer is composed up of acrylic acid blended with sodium hydroxide to form a three-dimensional network structure that can absorb 300 – 400 times water and retain large amounts of liquid relative to its own weight. The ability of water retention polymer depends upon the ionic concentration of an aqueous solution.  These polymers, also known as SAP, play a crucial role in water management, moisture retention, and enhancing the efficiency of various industries.



Let us understand some properties of Sodium based SAP.

·         High Absorbency: Possess the ability to absorb hundreds of times their weight in water.

·         Swelling Capacity: Upon absorbing water, acrylate polymer experiences extensive swelling, forming a gel-like substance that locks the liquid securely within it.

·         Retention under Pressure: Maintains their absorbency even under pressure.

Two most commonly used SAPs are Sodium Polyacrylate and Potassium Polyacrylate where the former finds usage in industrial applications whereas the latter, in agriculture. The extraordinary and remarkable absorption power of these polymers is due to their unique chemical structure and the presence of cross-linked polyacrylate chains. For instance, a small amount, when exposed to liquid, can transform into a gel-like substance within seconds. This property has led to their widespread use in various applications where moisture management is essential. In addition to their outstanding absorption capacity, SAPs are non-toxic and can be synthesized from renewable resources, further enhancing their sustainability profile.

Common Applications of Sodium Polyacrylate polymer

·         It is commonly used in hygiene products such as diapers, protective garments, etc.

·         In the medical field, polyacrylate-based SAPs find application in wound dressings.

·         It is also useful for many applications like Artificial Snow, Surgical dryers, Reusable hot/cold packs, ice gel packs, food packaging, and fire protection.

·         It is a valuable aid in the propagation of seedlings, promoting their successful establishment and growth.

Chemtex Speciality Limited has been supplying polyacrylate based super absorbent polymer to various industries such as detergent and soap manufacturing processes, wastewater treatment plants (where the molecules bind metal ions present in hard water with dirt and other contaminants, laundry, housekeeping chemicals formulators, etc. Due to its remarkably high absorption capacity and speed, Sodium Polyacrylate boasts a diverse array of uses in the production and processing of Fire-Retardant Gel, Candles, Protective Garments, Sanitary Napkins, Diapers, Insecticides, Pesticides, Herbicides, Composites, Laminates, Hot and Cold Therapy Packs, as well as various other related applications. Furthermore, this water-absorbing polymer plays a crucial role in safeguarding electrical and optical cables against moisture. When applied to the conductor, it effectively prevents water from seeping into communication and power cables, ensuring optimal signal transmission even under adverse rainy or flood conditions.

Acid Coil Cleaner leaves the aluminum surface clean and shining bright

Improper refrigerant levels, dirty coils, and worn out compressors or condensers can result in inefficient performance of air conditioning system. An inefficient system tends to force the compressor to work harder than is required decreasing its life span and thereby leading to higher energy bills. The primary energy required in operating an air conditioning system comes from the compression of refrigerant. The hotter the compressor receives the processed refrigerant, the more energy is necessary to force it through the condenser. The refrigerant needs to become cold enough to absorb more heat from the process, therefore an external chiller such as an open evaporative condenser or air blast unit is required. It is crucial for effective air-conditioning operation that the condenser is able to easily reject heat through the cooling airflow and the heat exchanger coils. Energy consumption builds up as the refrigerant vapor pressure increases, where the refrigerant is not sufficien...

Excellent Efficiency Flocculation with Polyelectrolyte

Polyelectrolytes are regarded as polymer chains with an electrolyte group on every repeat unit. When dissolved in a polar solvent, these polymers are charged due to dissociation of small counter ions that leave behind a charged macro ion. Polyelectrolytes include biologically important molecules such as polypeptides and DNA. These are referred to as polymers that are generally used for water purification. These are highly noted for their beneficiary nature of handling problems of slow settling of flocs in water at low temperature, treating soft colored water where they increase toughness of the flocs and enhance its settlement ability. Polyelectrolytes are formulated in a way so as to be used as coagulants and flocculants as well as a sludge dewatering agent in the waste water treatment plants. P olyelectrolyte , thereby, plays an indispensable part in the sludge conditioner formulation. Generally flocculation occurs owing to charges present on the particles. Generally, Pol...
