Spain Polyvinyl Alcohol

spain currently has a growing demand for polyvinyl alcohol (pva) in various industries. pva is a water-soluble synthetic polymer that is produced through the polymerization of vinyl acetate monomer. it is commonly used as an adhesive, coating agent, and thickener due to its unique properties such as water solubility, high tensile strength, and biodegradability. there are several types of pva available in the market, which are differentiated by their degree of polymerization and hydrolysis. the most commonly used types in spain are fully hydrolyzed pva, partially hydrolyzed pva, and ethylene vinyl alcohol (evoh) copolymers. fully hydrolyzed pva has the highest degree of polymerization and is the most water-soluble type, making it suitable for applications such as paper coatings, textile warp sizing, and adhesives. this type of pva has the largest demand in the spanish market due to the increasing usage of adhesives and coatings in the paper and textile industries. partially hydrolyzed pva, also known as intermediate pva, has a lower degree of hydrolysis and is less water-soluble compared to fully hydrolyzed pva. it is commonly used in the production of films, packaging materials, and detergents. the demand for this type of pva is also growing in spain, particularly in the packaging industry, as it provides excellent barrier properties against oxygen and moisture. evoh copolymers are partially hydrolyzed pva with the addition of ethylene units. this type of pva has excellent gas barrier properties and is used in the production of food packaging, medical packaging, and automotive fuel tanks. in spain, there is a steady demand for evoh copolymers, especially in the food packaging industry, as it helps to increase the shelf life of food products and maintain their freshness. the demand for pva in spain is also driven by the growth of the construction and packaging industries. pva is commonly used as a binder in construction materials such as cement and mortar, as well as in packaging materials for its adhesive and barrier properties. as these industries continue to expand, the demand for pva is expected to increase. in conclusion, the demand for pva in spain is primarily driven by its versatile properties and its usage in various industries. the availability of different types of pva allows for a wide range of applications, making it a preferred choice for many manufacturers. as the economy and industries continue to grow, the demand for pva is expected to rise, contributing to the overall growth of the spanish market.
