Polyurethanes / Elastomers Biobased thermoplastic elastomer compounds In response to increasing demands for sustainable alternatives to fossil based flexible polymer compounds, international compounding group, HEXPOL ® TPE, launched the Dryflex ® Green family of biobased Thermoplastic Elastomers (TPE) in 2015. Since then they have continued to develop the range, adding new possibilities to the biobased thermoplastic market by covering a wider range of hardnesses while incorporating high levels of renewable content. TPEs are often described as the bridge between rubber and plastics, they combine elasticity, flexibility and softness similar to rubber with the recyclability and processing advantages of plastics. Hexpol TPE were among the first companies to develop TPE compounds in Europe and they built on their 50 years heritage in the flexible polymers market in developing their biobased materials. Dryflex Green TPE compounds are available from 15 Shore A through to 55 Shore D. The range includes grades with biobased content over 90 % (ASTM D 6866), achieved by use of sustainable raw materials and feedstocks such as sugarcane, with recognised certifications such as ISCC+ and can derive from raw materials such as polymers, fillers, plasticizers or additives. For applications wanting a look even closer to nature, Hexpol TPE has developed compounds using organic fillers and natural fibres from plants, crops or trees, including cork, these give an additional ‘organic’ appearance. Cork is a natural product which comes from the bark of the cork oak tree. The removal of the bark does not harm the trees and the bark is only harvested after the first 20 years of growth. The removal stimulates a steady regeneration of the bark. Dryflex Green TPE compounds display mechanical and physical properties close to and comparable to TPE compounds from fossil based raw materials. In general the Dryflex Green compounds show very good bonding behaviour to PE and PP, special grades with good bonding to ABS, PET and PLA are also available. Like conventional TPE compounds, Dryflex Green TPEs can easily be coloured to give vibrant and appealing visual impact. Grades suitable for food contact are also available. Dryflex Green TPE compounds can be used in many applications that currently use conventional TPE and flexible polymers, such as soft-touch grips and handles, sealings, mats and closures, Klas Dannäs, Global R&D manager at Hexpol TPE commented “We’re seeing some very interesting development projects for the Dryflex Green materials; for applications ranging from household goods, sports equipment and toys to automotive interiors, packaging and infant care. Our R&D teams are constantly evaluating new polymer combinations and we have been working closely with suppliers to develop sustainable and ethical alternatives to fossil-based polymer compounds.” MT HEXPOL TPE worked with Wildo Sweden AB on the development of a biobased TPE for their iconic Fold-A-Cup.
