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.

当前，PTA加工费处于历史低位，同时，原油价格受俄乌冲突影响短期难以回落，PTA价值被低估。因此，即使终端消费不畅，PTA价格也将易涨难跌。

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.

Silicone sealants are employed to seal objects/surfaces that may be exposed to extreme environments, weathering, temperature, or movement for a prolonged period. Sealants are effective solutions that are elastic, flexible, durable, and reliable. Hence, they can be put to application in harsh conditions, ranging from construction, space, electronics, automotive, medical, and packaging. Silicone sealants are composed of silicone as a primary ingredient. The other essential components that provide silicone sealant their inherent properties are polymers, plasticizers, active reinforcing fillers, passive non-reinforcing fillers, cross linkers, and special additives. Silicone sealants based on their specific application can be readily modified using biobased materials. Through the addition of specific additives and fillers, they can be imparted enhanced electrical/thermal conductivity, resistance to fluctuation temperatures, and optical clarity, among others.

Although the raw materials required to manufacture paints and coatings have a relatively smaller margin (approximately 5%), they are extremely important components of the global chemicals industry. The different ingredients used to manufacture paints and coatings include resins, solvents, additives, pigments, and fillers. Resins are the most widely used raw materials as they account for around 49% of the total raw materials by value, followed by pigments and fillers, additives, and solvents. Coating resins are fundamental components of coating raw materials used to formulate paints and coating materials. Also, coating resins are added in small quantities to coating materials to enhance their features during manufacturing, storage, transport, and application.

The growing importance of personal hygiene and the maintenance of cleanliness in healthcare settings are the largest drivers for the global antiseptic wipes market. The rising awareness regarding the importance of hand hygiene is majorly driving the demand for antiseptic wipes among individuals. Many new hygiene habits are emerging among individuals that were not present before the COVID-19 pandemic. The COVID-19 pandemic is hence seen as a major driver for antiseptic wipes usage.

Endodontics is the study of science related to soft tissue surrounding the root of a tooth and dental pulp. Endodontics include endodontic retreatment, root canal treatment, dental implants and endodontic surgery. This study comprises products only and not the services. The study estimates the revenue generated from the sales of endodontic consumables. The valuations comprise revenue generated from the adoption of root canal procedures by patients. The study scope focuses on endodontics consumables for dental clinics and hospital and dental clinics. Furthermore, the report excludes revenue generated from post-sale services of endodontic consumables.

The Hydrogen Free Diamond Like Carbon Coatings DLC market is expected to grow strongly with the growth in the automotive industry, also increasing demand for high temperature coatings is providing huge opportunities for the DLC manufactures. The demand for hydrogen-free DLC is largely used by number of end-use industries due to its rigidity and wear resistance when compared to DLC that is combined with hydrogen. In the automotive sector hydrogen-free, DLC coating combines appropriately with the engine oil, which results in forming strong ultra-thin film when special oil additives are applied. Low friction factor and advanced abrasion resistance are increasing the demand for the DLC market. Manufactures in biomedical and automotive industry are aiming to use hydrogen-free DLC for effective working. Additionally, innovative technologies such as pulsed laser deposition and plasma enhanced CVD are expected to trigger the market for DLC
