Plastics have become an inseparable part of modern lifestyle since their formation. Plastics are used for packaging, building and construction, automotive, consumer goods, electronics, and medical devices. To make plastics usable and to increase their processability, plastic additives are required to modify polymer resin. This helps in enhancing several characteristics that manifold the value of plastic materials. Various types of additives such as flame retardants, heat stabilizers, lubricants, and slip additives, blowing agents, antistatic agents, antioxidants, and light stabilizers are used for the modification of polymer resins.

Adhesives are materials applied between two substrates (both metallic and nonmetallic substances) for gluing or bonding purposes. Today, adhesives have replaced bolts and rivets in several applications such as buildings, automobiles, and aerospace. Adhesives provide scope for innovating the design and shape of products. They are widely used in the automobile industry to make lightweight and fully efficient vehicles.

Over the last few years, personal care products have become part and parcel of consumer’s life. It includes array of product such as soaps, liquid soaps, hair gel, hair oil, shampoos, anti-aging face creams, sunscreen products and others. Chemicals used in personal care products range from basic metallic salts and fatty acids used in ordinary bath soaps to the high-end cosmeceuticals that offer beautifying properties of cosmetics with useful benefits of pharmaceuticals and chemicals.

Oleochemicals are chemicals derived from plant and animal oils. Oleochemicals include the formation of basic oleochemical substances like fatty acids, fatty alcohols, glycerine, methyl esters, and others. Intermediate chemical substances produced from the basic oleochemical substances include alcohol ethoxylates, alcohol sulfates, alcohol ether sulfates, quaternary ammonium salts, monoacylglycerols, diacylglycerols, structured triacylglycerols, sugar esters, and other oleochemical products. Oleochemicals are biodegradable, eco-friendly, and less toxic. The major oleochemicals are fatty acids, fatty alcohols, methyl esters, and glycerines, which are referred to as basic oleochemicals.

Nanofiltration (NF) is a membrane filtration-based process or liquid-separation technology that uses membranes with nanometer-sized pores to remove dissolved contaminants. NF membranes have pore sizes ranging from 1-10 nanometers, which is smaller than membranes used in microfiltration and ultrafiltration. However, the size of NF membranes is larger than RO membranes. NF membranes offer high rejection of multivalent ions (such as calcium) and low rejection of monovalent ions (such as chloride). The nanofiltration technology is used to recycle wastewater due to high flux rates and relatively lower energy consumption than RO technology. In addition, NF is often employed in the manufacturing process for pharmaceuticals, textiles, dairy products, and baked goods.

Degreasers are used to clean various types of equipment and machinery; they are used to clean or remove dirt, dust, and any foreign particles, and can be used for both residential or industrial purposes. Industrial degreasers are used to clean motor parts, machinery, and heavy equipment that are used in various end-user industries. They are powerful solvents that can handle numerous types of manufacturing parts, components, and heavy machinery. Hazardous substances such as paints, grime, grease, oil, lubricants, dirt, dust, corrosion, and sticky films that get accumulated over machines can easily be removed by using industrial degreasers. Industrial degreasers will remove these foreign particles as well as increase the shelf life of machines or equipment.

Dicyclopentadiene is a chemical compound with the formula C10H12. It is co-produced in large quantities in the steam cracking of naphtha and gas oils to ethylene as part of the separation process of crude C5 streams. It is a colorless, waxy, flammable solid or liquid with a camphor-like odor. Dicyclopentadiene is highly flammable, with a flashpoint of 90°F/32°C and a boiling point of 338ºF/170°C. The major uses are in resins, particularly unsaturated polyester resins. As a chemical intermediate, it is used for making insecticides, hardeners, and dryers in linseed and soybean oil and in the production of ethylene propylene diene monomer (EPDM) elastomers, metallocenes, resins, varnishes, and paints.

Fertigation is a method for applying fertilizers by incorporating the fertilizer into irrigation water by means of a drip, sprinkler, or center pivot system. In this system, fertilizer solution is evenly distributed during irrigation. Since nutrients are readily available, efficiency is higher. Liquid fertilizers, as well as water-soluble fertilizers, are used in this method. Using this method, fertilizer use efficiency can be increased from 80% to 90%.

Wood-based products are often prone to corrosion, destruction, and stains. A glossy wood coating prevents damage and increases the durability of wooden products, thus boosting their sales. It also makes wooden products desirable and aesthetically pleasing, thus luring customers into buying them. There are many wood coatings, including exterior wood coating, waterborne wood coating, radiation cure coatings, and wood finishing. Exterior wood coatings are extremely important in the furniture industry as they offer a good finishing and make furniture sturdy.
