Arlanxeo introduces new Keltan Eco based TPVs cradle-to-cradle applications

July 12/2018

MOSCOW (MRC) -- Arlanxeo, a global leader in performance elastomers, has introduced its new thermoplastic vulcanisates (TPVs) that combine Keltan Eco ethylene propylene diene monomer rubber (EPDM) with green fillers, plasticizers and thermoplastics, resulting in EPDM products with up to 90% sustainable ingredients, as per the company's press release.

Keltan Eco is the worlds first 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%.

After evaluating the potential of creating sustainable alternatives for traditional polyolefin thermoplastics, plasticizer oils and (reinforcing) fillers, ARLANXEO now developed thermoset rubber compounds and thermoplastic vulcanisates based on Keltan Eco EPDM with the specific aim of maximizing sustainable content without compromising technical performance.

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.

Niels van der Aar, Business Development Manager EPDM/NBR at ARLANXEO said: "We can now identify potential partners to (co-)develop these innovative bio-TPVs. TPVs using Keltan Eco EPDM offer an excellent opportunity to replace regular thermoset rubber compounds and thermoplastic vulcanisates. These bio-based TPVs can make a significant contribution to the circular economy, scoring well in a cradle-to-cradle approach and helping to lower the carbon footprint."

Studies have shown 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.

Today, these new bio-based EPDM grades are commercially tested and used in applications, such as window profiles for busses and buildings, automotive extrusion profiles, O-rings, TPV over-moldings for automotive interior, pharma applications, sport surfaces, and, most recently, in the sponge rubber layer directly underneath the outer cover of the official soccer ball of the Soccer World Cup 2018.

As MRC wrote before, in March 2018, Arlanxeo signed an agreement with Saudi Aramco Products Trading company, headquartered in Dhahran, the Kingdom of Saudi Arabia, pertaining to the marketing and sales of EPDM rubber.

Arlanxeo was established in April 2016 as a joint venture of Lanxess - a world-leading specialty chemicals company based in Cologne, Germany - and Saudi Aramco - a major global energy and chemicals enterprise headquartered in Dhahran, Saudi Arabia. The two partners each hold a 50-percent interest in the joint venture. The business operations of Arlanxeo are assigned to the High Performance Elastomers and Tire & Specialty Rubbers business units.
