Brief Introduction
Ethylene vinyl acetate copolymer (EVA) is obtained by copolymerization of ethylene and vinyl acetate in different proportions. E in the English abbreviation EVA stands for ethylene component, and VA stands for vinyl acetate component. Its performance is closely related to the content of vinyl acetate (VA). According to the different VA content, it can be divided into three categories: EVA plastic with VA content of 5% - 40%, which is mainly used for polyethylene modification Manufacturing wires and cables, film poles, other molded products and mixtures, etc; VA content of 40% - 90% is called EVA rubber, which is mainly used for rubber, cable and automotive industrial parts; VA content above 90% is called polyvinyl acetate emulsion, which is mainly used for adhesives and coatings.

Brief Introduction
As an important chemical raw material, polytetrahydrofuran is mainly used to prepare spandex in the field of chemical fiber. In the field of non fiber, polytetrahydrofuran is used to prepare elastomer, adhesive, coating, sealant and other fields. The polyurethane products prepared with polytetrahydrofuran have wear resistance, chemical corrosion resistance, good flexibility and resilience.

Brief Introduction
Hydroxybenzotriazole (HOBt), white crystal, 1n hydroxyl substituted derivative of benzotriazole. It is often used as racemization inhibitor in peptide synthesis. When DCC dehydration condensation is used to prepare peptides in the classical method, the chiral center of the substrate can not be well maintained in the product due to the high activity of DCC. Generally, additives such as hydroxybenzotriazole are added to reduce the activity of activated esters to inhibit racemization. See details See peptide synthesis. Hydroxybenzotriazole is usually sold as monohydrate crystal (~ 11.7% water, weight). Anhydrous hydroxybenzotriazole is explosive and should be paid attention to when used.
