Arlanxeo Formulated TPVs Using Sustainable Ingredients
Bio-Based EPDM Rubber
Keltan Eco is an EPDM rubber manufactured using bio-based ethylene extracted from sugarcane. Depending on the ethylene content of each rubber grade, the proportion of bio-based material ranges between 50% and 70%.
TPVs Using Keltan Eco EPDM
After evaluating the potential of creating sustainable alternatives for traditional polyolefin thermoplastics, plasticizer oils and (reinforcing) fillers, Arlanxeo developed thermoset rubber compounds and thermoplastic vulcanisates based on Keltan Eco EPDM with the specific aim of maximizing sustainable content without compromising technical performance.
The manufacturer indicates that by combining Keltan Eco EPDM with green compounding ingredients the new EPDM compounds can also be used for dynamic and static automotive sealing applications with 85 to 90 weight percent of its composition having sustainable origin and a technical performance comparable to standard EPDM compounds.
According to the manufacturer, there are also studies that show that both the characteristics and technical performance of these Keltan Eco EPDM grades are identical to those of conventional EPDMs produced via Ziegler Natta catalysis and/or those from monomers based on crude oil.
