Application of Vulcanization Accelerators in Polymers

  Why should vulcanization accelerators be used? After more than 100 years of development, the world rubber industry has become an important traditional industry in many developed countries. However, rubber products cannot withstand extreme high and low temperatures, which causes them to become fragile and susceptible to degradation during seasonal changes. American inventors discovered that removing sulfur from rubber and then heating it would allow the rubber to retain its elasticity and harden. This process is known as vulcanization. Vulcanization accelerators act as special compounds that minimize the degradation of rubber and speed up the vulcanization process, thereby improving the mechanical properties of rubber (e.g., strength, elasticity, hardness, abrasion resistance). It can be said that the use of vulcanization accelerator has opened a new door for the rapid development of rubber products. Applications The main market sectors for vulcanization accelerators are the auto...

Uses of Titanium Dioxide

The main applications of titanium dioxide include coatings and paints, plastics, inks, papers, chemical fibers, medicines, foods, cosmetics and others which is closely related to people's life and national economy. Use of Titanium Dioxide in Coatings and Paints About 60% of the world's titanium dioxides are used in all kinds of coatings and paints. It can be said that coatings and paints are the first destination of titanium dioxide. The use of titanium dioxide makes the coatings and paints with more bright color and higher hiding power. It also can improve the hardness, adhesion, UV resistance of the coatings and paints and extend their service life. Titanium dioxide is used in almost all color...

Applications of Drug Metabolites in Medicine

Drug metabolites are compounds produced by the chemical transformation of drugs in the body. They are related to the safety and effectiveness of the drug. Over the past two decades, there has an increasing focus on the importance of pharmacokinetic data in the drug discovery process. The metabolism of a new drug by the host system is one of the most important determinants of its pharmacokinetic disposition [1] . In some instances, metabolic transformation of drugs can also produce reactive or toxic intermediates or metabolites, which have potential toxicological implications [2] . Hence, there is a need to insight into the metabolic process of a new drug early in the drug discovery process, which relies on the study of drug metabolites. Alfa Chemistry is an expert of drug metabolites, we have the ability to provide professional advice on your drug research.
