Polyvinyl Butrayl
The polyvinyl butyral is a hot-melt polymer compound in the form of white or yellowish powder particles. With high transparency, flexibility, high impact strength at low temperature, resistance to sun exposure, oxygen and ozone, wear resistance, resistance to inorganic acids and aliphatic hydrocarbons and other properties, and can and nitric acid fiber, phenolic, urea-formaldehyde, epoxy resins are mixed with the other phase to improve their performance. Soluble in alcohols, ethyl acetate, methyl ethyl ketone, cyclohexanone, methylene chloride and chloroform. It has good cold resistance and adhesion, and has good adhesion to metal, wood, ceramic, leather and fiber. Can be used for the intermediate layer and coating of safety glass.
VAM
Vinyl acetate is an organic compound with the formula CH3CO2CH=CH2. This colourless liquid is the precursor to polyvinyl acetate and ethene-vinyl acetate copolymers, important industrial polymers
Vinyl acetate monomer (VAM) is a significant intermediate used in the production of a wide range of resins and polymers for paints & coatings, adhesives, glues & sealants, elastomers, textile finishes, paper coatings, binders, films, and a myriad of other industrial and consumer applications. It efficiently homo-polymerizes to polyvinyl acetate (PVA), and VAM can be used in numerous random copolymers and terpolymers such as ethylene-vinyl acetate copolymers, vinyl-acrylic resins, vinyl acetate-acrylic acid copolymers, and vinyl acetate-vinyl chloride copolymers. With the wide diversity of polymerization options, VAM has allowed the design of products with a wide spectrum of cost and performance profiles.
PVA
Polyvinyl Alcohol (PVA) is a water soluble and biodegradable synthetic polymer. It is a dry solid, and is available in granule and powdered forms. Grades include both fully hydrolyzed and partially hydrolyzed. PVA is an excellent adhesive with superior bonding strength, film forming and emulsifying properties.The film of PVA exhibits outstanding resistance to oil, grease and solvents. In addition to its film forming property, it has excellent adhesion to both hydrophilic and hydrophobic materials. PVA has been extensively used in textile industry for warp sizing and resin finishing; in paper industry for surface sizing and pigment coating; in the production of PVAc emulsion as protective colloid; in the suspension polymerization of PVC as a dispersion agent; as binder for ceramics, magnet, foundry cores and pigments.
