Everyone is very familiar with the phrase when buying a house: All that really matters are three things - location, location, and location. This same principle applies to extractables and leachables chemistry analysis – the three things that truly matter are identification, identification, and identification. The greatest growth in the past ten years in demonstrating the safety of medical devices and container closure systems for drugs has been using analytical chemistry to determine what chemicals can leach from the device and what the patient is exposed to during its intended use.

The initial versions of drugs were produced by extracting substances from natural herbs and other plants. As understanding and technology in chemistry continued to grow, scientists figured out to isolate and extract a lot more individual compounds from raw materials. The complicated processes that produce these simple, pure substances form the field of fine chemistry. The chemical industry is separated into branches, with fine chemicals serving as the smallest segment of them. Its companions are commodities and specialty chemicals. Commodity chemicals are those that are mass-produced on a big scale to supply global markets. They include general compounds that are the same from supplier to supplier. Specialty chemicals usually are sold as brand name products and are advertised for their distinct qualities and their abilities to carry out functions that other chemicals cannot. They are composed of one or more fine chemicals.

With a more increased focus on adding more recycled content to products, it’s becoming very apparent that innovation is required in order to meet these demands. During the Plastics Recycling Conference, Canadian cleantech company GreenMantra Technologies accepted the Association of Plastics Recyclers (APR) Showcase Award, which is given to companies who have a innovative and potentially game-changing idea to advance the recycling of plastics. GreenMantra Technologies is a clean technology company that utilizes a proprietary catalyst and patented depolymerization process to upcycle and transform recycled plastics into value-added synthetic waxes and specialty polymers.

The market size for polymeric and resin binders in the global printing ink marketwas estimated to be over 1,200,000 MT in 2020, with a CAGR of about five percent. A major driver of this growth comes from the packaging industry, due to increases in consumer spending and online shopping, as well as demand for processed and packaged foods and beverages.
In addition, increased use of water-based inks is promoting market growth, off-setting environmental and health concerns regarding solvent-based inks in addition to strict environmental protection policies. Water-based inks are projected to overtake solvent-based inks due to environmental regulations, the reduction of volatile organic compounds (VOCs) in the pressroom, and improvements in overall print quality.
Ink formulations are complex mixtures, consisting of four basic component classes: pigments, polymeric binder resins, solvents or an aqueous dispersant media, and additives, such as surfactants, waxes, and rheology modifiers that enhance print quality. The purpose of the resin binder is to disperse and carry the ink pigment to the substrate, stabilize the pigment and additives dispersion to prevent settling, and provide print properties such as ink transfer behavior, setting, and drying characteristics. The binder also contributes surface appearance and gloss, strength and flexibility, chemical and solvent resistance, and also rub resistance. Ink binders can be categorized into the following polymer and resin types: acrylics, polyurethanes, polyamides, modified resins, hydrocarbon resins, and modified cellulosics.
