The latest application progress of polyvinyl alcohol (PVA)

1.Polyvinyl alcohol (PVA) 3D printing materials

PVA has good water solubility, biocompatibility and mechanical properties. As a polymer 3D printing material, it is mainly used as tissue engineering scaffold material, drug loading material, water-soluble support material and soluble mold material. PVA can be used to make 3D printing PVA soluble mold materials, 3D printing PVA water-soluble supporting materials, 3D printing PVA water-soluble supporting materials, 3D printing PVA water-soluble supporting materials and other materials.
2.Polyvinyl alcohol (PVA) optical film

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

3.High-strength and high-modulus polyvinyl alcohol (PVA) instead of asbestos

In recent years, developed countries such as Europe and the United States have adopted high-strength and high-modulus PVA to replace asbestos, and have achieved good results in the manufacture of asbestos-free cement boards. High-strength and high-modulus PVA has a unique cross-sectional shape and good adhesion to cement. It has performance advantages and high cost performance in replacing asbestos. It is known as the most ideal “green and environmentally friendly” substitute for asbestos. High-strength and high-modulus PVA fiber has the characteristics of high strength and Young’s modulus, low elongation, acid and alkali resistance, and solvent resistance. At the same time, it has good hydrophilicity, adhesion, impact resistance and easy processing. Dispersion and other characteristics. The function of high-strength and high-modulus PVA fiber is particularly advantageous in preventing segregation settlement cracks, plastic cracks and shrinkage cracks in the early stage of concrete.

Moreover, with the continuous improvement of people’s living standards, people’s awareness of health and environmental protection has gradually strengthened, and the replacement of asbestos with high-strength and high-modulus PVA fibers has gradually become an inevitable trend.

4.5G applications of polyvinyl alcohol (PVA)
With the accelerated construction of 5G, the LCP (liquid crystal polymer) market is growing rapidly. The future of LCP mainly comes from two application growth brought about by 5G promotion: LCP particles for connectors and LCP films for mobile phone antennas. 5G uses more high-frequency signals, and has higher requirements on the dielectric constant and dielectric loss of the material. PVA happens to have superior LCP performance and is expected to be used in the field of 5G high-frequency film and packaging.
