The chemical composition of human hair is approximately 45 % carbon, 28 % oxygen, 7% hydrogen, 15 % nitrogen and 5 % sulfur. These elements make up the amino acids, keratin and protein in hair. At least 16 amino acids are present in hair, with cysteine the most important.
Insoluble sulfur exists in rubber in a dispersive state. It can prevent the booming of rubber, having a better viscosity, and at the same time can ensure the outer appearance of the products with light color. 2. Insoluble sulfur can disperse uniformly in rubber, so it can prevent the conglomeration of sulfur, and reduce the tendency of being

Lab-Scale Twin-Screw Micro-Compounders as a New Rubber
The research and development (R&D) in rubber formulation development require reproducible, repeatable, fast, accurate, and efficient sample preparation. The lab-scale formulation development is conventionally carried out using small-scale internal mixers and two-roll mills. However, high torque laboratory twin-screw micro-compounder, which have been
