63450-15-7 - Introduction
POLY(VINYL FORMAL), also known as PVA FORMAL, is a polymer made by polycondensation of polyvinyl alcohol and formaldehyde. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance is white to yellow crystalline powder.
-has good solubility, soluble in water. Form viscous liquid after dissolution.
-It has good adhesion and bonding properties.
-High heat resistance and chemical stability.
-has a certain tensile strength and wear resistance.
Use:
- POLY(VINYL FORMAL) is commonly used to prepare glues and adhesives, and can be used to bond paper, fibers, plastics and other materials.
-Can also be used to prepare coatings, inks and printing materials.
-Thickening agent for pulp and dyes in textile industry.
-Can be used to prepare membrane materials, such as water-soluble films and biodegradable materials.
Preparation Method:
The preparation of-POLY(VINYL FORMAL) is usually carried out by polymerization. Formaldehyde is first added to the polyvinyl alcohol solution, and then the polymerization reaction is carried out under certain temperature and pressure conditions, and finally POLY(VINYL FORMAL) is obtained.
Safety Information:
- POLY(VINYL FORMAL) has certain toxicity, so it is necessary to pay attention to safety precautions when using.
-Avoid direct contact with skin and eyes, and wear protective gloves and goggles when using.
-Avoid inhaling the aerosol of its dust or solution, and maintain a well-ventilated working environment.
-In case of contact with skin or eyes, rinse immediately with water and seek medical help.
-In storage and handling, should follow the relevant safety procedures.
