Product Technical Details

Product Overview

Nucleating Agent 3988 represents an advanced generation of sorbitol-based clarifying additives specifically engineered for polyolefin matrices. Chemically identified as 1,3:2,4-di-O-m,p-dimethylbenzylidene-D-sorbitol, this compound serves as a highly efficient nucleating agent that significantly enhances the physical and optical properties of polypropylene and related polymers. Unlike traditional additives, this material is designed to overcome historical limitations regarding transparency, organoleptic properties, and processability while delivering superior nucleation capability.

Our manufacturing process ensures high purity levels, making this agent suitable for demanding applications including food contact materials and odor-sensitive environments. The unique molecular structure facilitates the formation of a fine crystalline network within the polymer, resulting in improved stiffness, heat distortion temperature, and surface gloss without compromising toughness or flexibility.
