Nucleating agent BTD-8808 is a special nucleating agent for polylactic acid (PLA) that exhibits excellent compatibility with PLA resin. It remains stable at processing temperatures and can induce epitaxial crystallization of PLA molecules during the cooling process of PLA resin melt. This process accelerates crystallization speed, shortens the molding cycle, and enhances the heat resistance, bending modulus, and surface gloss of the product. BTD-8808 is suitable for use in food contact materials.
The recommended usage of BTD-8808 is 0.3~0.5 phr based on the weight of the resin. When used in combination with PLA or other resin particles, other dispersing agents can be appropriately added to promote uniform dispersion.
