PLA is one of the most commonly produced bioplastics today. As a renewably sourced biobased material that is certified compostable according to EN 13432:2000, PLA is a popular and familiar choice in a host of applications.

PLA is easily processable on all standard processing equipment and is suitable for food contact and cosmetics packaging applications. Its drawbacks, however, are equally well known: PLA has poor mechanical and thermal properties. Its low impact resistance, brittleness and low thermal degradation temperature (55°C) have long served to hamper its use in higher-end applications. 

For some years, heat-resistant PLA grades offering a thermal stability up to 120°C have been available on the market, although in injection molding, their use comes at a price: the significantly higher cycle times mean a loss off productivity, compared to a nonmodified PLA.

Biopolynov, Natureplast ‘s research subsidiary has successfully developed and is now introducing two new PLA grades - PLHT 201 and PLHT 202 - that overcome these problems. The new grades are characterized by improved mechanical and thermal properties as compared to standard PLA, and improved productivity as compared to existing heat-resistant PLA grades, all at a competitive price. Trials showed gains in cycle times varying from 30% up to over 200%, depending on the parts injected.

According to Natureplast, the properties of PL HT 202 are comparable, or even superior (in terms of thermal and impact resistance) to those of a conventional technical material, such as ABS. The company claims that the new PL HT grades can also be used to replace traditional high-impact PS, as they offer an over 40% higher impact strength. 
As a result of these improved properties, applications in areas such as the automotive industry and electronic consumer goods are now opening up that had up until now not been possible. 

Since 2006, Natureplast has been the only company in Europe that can supply bioplastics from all around the world from a hundred different producers. Its subsidiary Biopolynov, founded in 2010 is still the only R&D European center dedicated to these new materials. (KL)
