9results about How to "High haze" patented technology

This invention discloses a high-transparency, high-haze polypropylene material and its preparation method. The material is prepared by mass ratios of 93.2-98 parts polypropylene, 1-4 parts light diffusing agent, 0.2-0.6 parts α-nucleating agent, 0.2-0.6 parts β-nucleating agent, 0.2-0.4 parts antioxidant, 0.2-0.6 parts dispersant, and 0.2-0.6 parts light stabilizer. The nucleating agent is a compound of α-nucleating agent and β-nucleating agent in a mass ratio of 2-5:2-6. By adding specific proportions of α-nucleating agent and β-nucleating agent, this invention induces the polypropylene molecular chains to arrange themselves in a specific manner, thereby forming different spherical (α-crystal form) and rod-shaped (β-crystal form) crystal structures. This causes optical fibers that pass through the material surface and into the matrix to undergo multiple refractions before penetrating the matrix, thus increasing the path length of light within the material and enabling the material to maintain high transparency while exhibiting higher haze.
