TOP Partially biobased PP Compound for injection molding applications

FKuR Kunststoff GmbH is now offering a PP compound made from renewable resources which maintains the typical characteristic and performance of PP

Terralene® compounds are customized blendes based on the raw material „I ́m Green“ polyethylene from Braskem. Terralene® compounds are suitable for a wide range of applications and processes e. g. injection molding, extrusion blow molding and film extrusion. In addition, there are Terralene® WF grades containing natural wood fibers which meet special requirements as to design, look, feel and mechanical characteristics.
To date, there hasn’t been a pure bio-based solution in PP even though the market has been searching for such a solution. As such, it was only logical to modify PP as a further important and versatile polymer.
FKuR Kunststoff GmbH is now offering a PP compound made from renewable resources which maintains the typical characteristic and performance of PP. The grade offered under the brand name Terralene® PP 2509 is ideally suitable for injection molding. The flowability of the material with an MFR of 42 – 47 [g/10 min], measured at 230 °C, is excellent for a bioplastic. With this material, it’s possible to produce complex parts with long flow paths.
„For us, it was important to develop a material which can be easily processed by injection molding, presenting PP characteristics but containing an appealing share of renewable resources“, says Carmen Michels, Managing Director at FKuR and responsible for technology and development.
The biobased carbon content of this grade is about 35% and can be easily quantified by means of a C-14 measuring method (according to ASTM D 6866). This enables a transparent communication of the renewable resource content to the end consumer. With Terralene® PP 2509 manufacturers and brand owners are in the position to produce their PP products in a partially biobased version and occupy an important market niche.
