Version 6, April 2015 (additions are donoted in underlined text) began generating SDSs with GHS hazard classifications for new formulations, or existing formulations with significant changes. The only PolyOne products that will then use the new format for SDS will be new formulations, or existing formulations with significant changes. Many of PolyOne’s products encapsulate additives in the polymer matrix, or in a physical form such that they are not available in the route required to be classified for that hazard.

SBC compounds offer good economics and formulation flexibility meeting the end use performance requirements. Formulation Development Based on the market feedback, the developmental TPE needed to meets three major general requirements;, clarity, heat resistance and softness. It is known that transparent polymer blend can be made of polymers with different refractive index provided the dimension of the dispersed phase is below the visual wavelength.

In effect, the surface energy is changed to allow a fluid to ‘roll off’ the polymer material. KEY CHARACTERISTICS • Eliminates secondary coating operations • Easily delivers the last drop out of a container • Reduces residual content • Reduces production costs • Won’t impact visual clarity • Non-PFAS formulations available APPLICATIONS Cesa Low Retention Additives are suitable for any olefinic application that would benefit from the ability to repel water or fluids, including: • Labware, including pipette tips • Monofilaments • Industrial fixtures • Woven fibers • Platform mats • Molded optical lenses • Medical devices • Extruded films • Carpet fibers • Textiles PRODUCT BULLETIN

THE SOLUTION The Avient technical team leveraged expertise in liquid formulations with the science of dispersion to develop Excelite™ IM, a CFA solution that targeted automotive injection molding applications and would help address the issues of this tier-1 molder. Using conventional CFA ingredients, a special conditioning process was used to prepare the raw material for optimal foaming performance upon polymer interaction.
