Polyester-Specific Dendritic Internal Lubricant

CYD-C600
CYD-C600 is a high-temperature resistant dendritic structure additive with special functional groups developed by Weihai Chenyuan Molecular New Materials Co., Ltd. It significantly improves the processing fluidity and mechanical properties of PBT and PET polyester systems, enhances the dispersion of fillers or flame retardants in the system, effectively addresses surface defects, and improves the gloss of the finished product surface. It is widely used in 5G, new energy vehicles and other automotive industries, rail transportation, electronic components such as mobile phones, and plastic products such as instrument housings.

Features Technical Indicators Overall Dimension

1. Internal lubrication effectively improves the flowability of PET and PBT products, increasing melt flow index by over 50%. It effectively solves problems such as incomplete injection molding and material shortages caused by multiple parts produced in a single injection mold, and also improves the flowability of large, thin-walled products.
2. Effectively improves the overall mechanical properties of products, increasing elongation at break by over 100% and flexural strength by over 10%, without affecting impact and tensile strength.
3. Effectively reduces melt pressure and main machine current, effectively increasing production capacity.

I. Product Overview

CYD-C600 is high temperature resistance additive of dendritic structure with special end groups. It can obviously improve fluidity and mechanical performance of PET etc., and also well disperse fillers and flame retardant in the formulation, effectively solve the surface problem. CYD-C600 is widely applied in the automotive industry, machine part, electronic parts, instrument shell etc.
