Alfa Chemistry recently announces the launch of varieties of heat stabilizers , which are largely used in the medical-grade PVC industry, where they play the role of inhibiting the chemical break-down and discoloring of polymers under heat. After all preparation work, Alfa Chemistry is able to supply a wide range of polymer stabilizers, including: antioxidant, flame retardant, heat stabilizer, light stabilizer, mould inhibitor, optical brightener, plasticizer, synthetic auxiliary, and vulcanization accelerator. Among them, heat stabilizers are added to materials to help them resist the damage that can stem from exposure to high temperatures. “Of all major commercial thermoplastics, PVC is the most heat sensitive. Therefore, they need heat stabilizers to protect them against thermal stress during processing. The protective effect will also be extended to their service life later on,” says the Marketing Chief of Alfa Chemistry. At present, a comprehensive range of heat stabilizers are av...

As a worldwide recognized supplier of fatty acids and lipids, Alfa Chemistry recently announces a decision to release a comprehensive product line of sphingolipids , including subtypes like sphingomyelins, glycosphingolipids, gangliosides and more. All these high quality sphingolipids are fast-delivered and are purposed to support many research projects in multiple fields. First discovered in brain extracts in the 1870s, sphingolipids are a class of lipids containing a backbone of sphingoid bases. Till now, sphingolipids are found in the membranes of all animals, plants, fungi, and in some prokaryotic organisms and viruses. “Over the past couple of decades, the structure, biosynthesis and degradation of sphingolipids have been intensively studied as they are found to be involved with a wide range of biological processes. Furthermore, they are also fundamental players in the regulation of human health with regard to inflammation, infection, cancer, psychiatric disorders and neurological...

A mong varieties of surfactants, natural surfactants have gained an increasing interest due to their unique properties such as low toxicity and functionality under extreme conditions.

Reinforcing materials and fillers In many plastics, reinforcing materials and fillers occupy a considerable proportion. In order to improve the strength and rigidity of plastic products or reduce production costs, various fiber materials or inorganic substances are added. The most commonly used reinforcement materials are: glass fiber, asbestos, quartz, carbon black, silicate, calcium carbonate, metal oxides, etc. Coupling agent Coupling agent refers to a class of substances that can improve the interface properties between fillers and polymer materials. Usually there are two functional groups in the molecular structure of the coupling agent: one can chemically react with the polymer matrix or have good compatibility; the other can form chemical bonds with the inorganic filler. For example, silane coupling agent, the general formula of which can be written as RSiX 3 , where R is an active functional group that has affinity and reactivity with polymer molecules, such as vinyl, chl...

Functional polymer materials originated in the late 1960s. By modifying reactive groups on the polymer, it has special functions with regard to chemical reactivity, catalytic activity, electrical conductivity, and biocompatibility. Compared with traditional polymer materials, functional polymer materials have attracted much attention because of their special properties brought by modified special groups besides. The focus of current research is mainly on the relationship between the properties of functional polymers and their structures. Through continuous research and development of new structures and synthesis methods of functional polymers, emerging functional polymers with more functions are screened out and the application fields of functional polymer materials are broadened.
