ATOFINA Chemicals, Inc.
ORGASOL® ultrafine polyamide powders are polymers and copolymers of lauryllactame and/or caprolactame obtained by direct polymerization. Due to this unique process, these powders are available as micro-porous spherical beads with a very narrow particle size distribution. Grades differ in particle size (from 5 to 60 microns), specific surface area and melting point. They offer abrasion and scratch resistance, gloss control, coefficient of friction control and soft feel. Visit www.AtofinaChemicals.com.
