After demonstrating an intriguing ability to reduce the surface tension of polar and non-polar liquids, silicone surfactants now receive considerable attention worldwide. Earlier this month, Alfa Chemistry announced its  new wide range of high-performance silicone surfactants  for both researchers and manufacturers. Surfactants often act as detergents, wetting agents, emulsifiers, foaming or defoaming agents, and dispersants across a wide range of consumers and industrial applications. As copolymers of silicones and polyethers, silicone surfactants exhibit high dispersion capabilities, formulation flexibility, and multi-performance attributes, which allows their use in common personal care products such as creams, gels, and sticks. Statistically, studies found that if the silicone surfactant possesses oil- and silicone-soluble groups, the surface tension lowers to 20 dynes/cm 2 . “A lowered surface tension is a necessary step for processes such as wetting, detergency, spreadin...

As an innovator and leader in surface coating technology, Alfa Chemistry develops effective solutions that modify various surfaces from metals, glasses, and polymers. Earlier this month, Alfa Chemistry launched a comprehensive portfolio of hydrophobic polymers , which aims to make breakthroughs for both researchers and industrial manufacturers. The newly released hydrophobic polymers are wide-ranged and encompass Acrylic Hydrophobic Polymers, Amic Acid Solution, Carbonated Polymers, Ether Polymers, Fluorocarbon Polymers , Nylon Polymers, Poly(N-Vinylpyrrolidone) Polymers, Poly(Tetrahydrofuran) Polymers, Poly(Vinyl Chloride) Polymers, Polyacetate Polymers, Polybenzoic Acid Polymers, Polybutadiene Polymers, Polyethylene Polymers, Polypentadiene Polymers, Polypropylene Polymers, Polystyrene Polymers, Polyvinyl Pyridine Polymers, etc. “The field of surface chemistry has undergone an explosive development ever since its debut. With advances made within the past ten years, the research commu...

Aerospace materials require the highest standards for reliability, as the failure of any key components would result in catastrophe or immeasurable losses. Hence, in a recent statement, Alfa Chemistry’s testing branch, T,C&A Lab, announced plans to provide one-stop solutions for aerospace materials testing , aircraft and parts manufacturing companies, aircraft operators and maintenance companies, as well as aviation materials production and development organizations. In the aviation industry, it is of paramount importance to verify raw materials, analyze failures, and conduct thorough tests on new products in order to maintain high safety standards. “Aviation materials should meet the most stringent requirements such as high specific strength, high specific stiffness, excellent resistance to high and low temperature as well as good aging resistance and corrosion resistance,” said a senior scientist from T,C&A Lab. “Our team of metallurgists, chemists, mechanical engineers can p...

Fully aware of the importance of customized preparation for graphene material in downstream applications, Alfa Chemistry announced the commencement of offering graphene dispersion customization  service earlier in June. The company is known as a reliable supplier of various forms of graphene and related customization services. Making use of its advanced R&D technologies, Alfa Chemistry can disperse single-layer graphene, graphene oxide , or reduced graphene oxide well in solvents, such as DI Water, EtOH, NMP, DMF, and THF. The concentration ranges from 1 ~ 30 mg/mL upon customers’ request, the number of graphene layers could be 1 ~ 5, and the final concentrate suspension of graphene is usually brown or black in color. “Leveraging the exceptional properties of graphene usually requires its dispersion into different solvents. Therefore, to make graphene applicable and environmentally safe for coating, composite, and other material applications, our laboratory staff can handle a...

As a sub-branch of Alfa Chemistry, Alfa Chemistry Testing Lab recently announced its capability to conduct practical analysis for household cleaners, toiletries, industrial detergents,   general cleaners ,   and other products. This   newly launched detergents and cleaners testing   service aims to advance the R&D process of detergent product s and offers a   comprehensive report issued by a third-party testing lab that will certify   that products are made in compliance with relevant regulations and standards. " Cleaners, dish-washing liquids, and laundry detergents are part of our everyday life. Consumers may wonder if these products really meet the safety and environmental standards. Our testing lab offers a way to crystallize out these puzzles, "   states   the Marketing Chief of Alfa Chemistry Testing Lab.   " After a detailed inspection o f   the provided sample, individual customers can have a clear understanding of the qualit...

Shortly after the launch of fatty acids and esters, glycerides, fatty alcohols, wax esters, and sphingolipids, the management of Alfa Chemistry decided to add sterols   to its diversified product line of lipids. This move is made in response to the request of valued scien tific   customers as their interest in sterols has risen   over the last decade. Like other forms of lipids and fatty acids, sterols exist extensively in nearly all species, including animals, green plants, and fungi. Evidence shows that stanol or sterol esters behave extraordinarily well in lowering the total and LDL cholesterol levels and ,   in some cases ,   help prevent heart diseases. In this sense, the health benefits brought by stanol-rich foods are beyond measure. “S terols  are referred   to as phytosterols that present in the membranes of plants, and refer red to as zoosterols and mycosterols in animals and microorganisms, respectively, ”   sa id  one of the senio...

Petrochemical products are an integral part of modern societies. To help researchers assess the quality of these commodities, Alfa Chemistry, one of the most popular suppliers of analytical reagents, recently announced the release of a new line of petrochemical standards , which can be used to analyze and test petroleum, gasoline, fuels, hydrocarbons and many other types of petrochemical-relevant substances. The global economies are heavily dependent on petrochemicals. Experts believe petrochemicals will exert more influence on future energy systems as they have already found use in solar panels, wind turbine blades, batteries, and many other energy applications. “While petrochemical products are extensively applied in various industrial scenarios, researchers need to evaluate their physical and chemical properties accurately and efficiently to ensure their safety and efficiency in use,” says one senior scientist from Alfa Chemistry. “Therefore, we designed and launched a comprehensive...

Photodegradation may lead to undesirable changes in the properties of plastics and rubbers ,   such as tensile strength, color ,   or shape. Therefore, light stabilizers are added to extend the life cycle   and improve the appearance of polymers. Earlier this month, Alfa Chemistry announced the launch of varieties of light stabilizers , a kind of additives that are uniquely developed to minimize or prevent the damage to polymers caused by exposure to the environmental parameters of light, heat ,   and air. The degradation damage caused by UV radiation include s : color fading, deterioration of mechanical properties, and the formation of visible defects such as cracks. A ccording to different  mechanism s  of action, l ight stabilizers can be divided into the following categories: the l ight screener, UV absorber, q uencher   as well as   f ree radical scavenger . “ As derivatives of 2,2,6,6-tetramethylpiperidine, hindered amine light stabilizers (...
