What are the PVA polymer uses with high-value？

PVA polymer is a widely used water-soluble polymer with properties between plastic and rubber. It can be used as slurry, coating, adhesive, stabilizer, dispersant, emulsifier, thickener, photosensitizer and filler. In addition, What are the PVA polymer uses with high-value?

1. PVA polymer uses in 3D printing materials

PVA polymer has good water solubility, biocompatibility and mechanical properties. As a polymer 3D printing material, it is mainly used as a tissue engineering scaffold material, drug loading material, water-soluble support material and soluble mold material. PVA polymer can be used to make 3D printing PVA polymer soluble mold material, 3D printing PVA polymer water-soluble support material, etc.

In medical applications, PVA polymer microparticles have been approved by the FDA for use as embolic particles. In biomedical engineering research, PVA polymer has been studied as a material for artificial cartilage, orthopedic medical use, and artificial transplant blood vessels.

2. PVA polymer uses in optical film

PVA polymer optical film is a thin and uniform dielectric film layer attached to the surface of optical devices with PVA as the main material. During the light propagation process, through the reflection, transmission and polarization characteristics of the film, special forms of light within one or more bands can be obtained. PVA optical films are widely used in liquid crystal panels, and the products mainly include anti-reflection films, polarizers, wide-angle films, prisms, diffusion films, reflective films, etc.

3. High-strength and high-modulus PVA polymer use to replace asbestos

In recent years, developed countries such as Europe and the United States have adopted high-strength and high-modulus PVA polymer to replace asbestos, and have achieved good results in the manufacture of asbestos-free cement boards. High-strength and high-modulus PVA polymer has a unique cross-sectional shape and good adhesion to cement. It has performance advantages and high cost-effectiveness in replacing asbestos. It is known as the most ideal "green and environmentally friendly" substitute for asbestos. High-strength and high-modulus PVA polymer fiber has the characteristics of high strength and Young's modulus, low elongation, acid and alkali resistance, solvent resistance, etc. At the same time, it has good hydrophilicity, adhesion, impact resistance and easy dispersion during processing. In terms of preventing segregation settlement cracks, plastic cracks and shrinkage cracks that are prone to occur in concrete at an early stage, the high-strength and high-modulus PVA polymer has a particularly obvious advantage.

4. PVA polymer uses in 5G application

With the accelerated construction of 5G, the LCP (liquid crystal polymer) market is growing rapidly. The future of LCP mainly comes from the growth of two applications brought about by the promotion of 5G: LCP particles for connectors and LCP films for mobile phone antennas. 5G uses higher-frequency signals and has higher requirements for the dielectric constant and dielectric loss of materials. PVA polymer has superior LCP performance and is expected to be used in the field of 5G high-frequency films and packaging.
