HALLGREEN®
HALLGREEN® BIO-BASED POLYMER MODIFIERS The HallStar Company has a proud, 90-year history of providing leading-edge chemical solutions in all types of polymers. Our newest product line is our HALLGREEN® environmentally responsible, polymer modifiers for use in PLA, PHA, starch-based and other bio-polymers and hybrids. These esters are derived from renewable raw material streams and/or are biodegradable according to ASTM-D6400. HALLGREEN® products function as process aids, as well as polymer and impact modifiers. They improve processing by reducing melt viscosity/temperature, and energy consumption. As a polymer / impact modifier, they reduce brittleness, improve impact resistance and improve extruder flow rates and throughputs. Select products have FDA and/or EINICS acceptances. HALLGREEN® R-8010 is a renewable polymeric ester, 100% bio-sourced, and imparts excellent flexibility to PLA compounds. HALLGREEN® R-9010 is completely biodegradable under ASTM D6400 Standard Specification for Compostable Plastics, EN13432 Requirements for packaging recoverable through composting and biodegradation and ISO 17088 Specification for compostable plastics. See the following Functionality Grid followed by links to specific product:
