PLA is a biobased polymer derived from natural resources and offers a significant reduction in carbon footprint compared to oil-based plastics. Total Corbion PLA homopolymer resins are available in a range of melt viscosities and deliver improved heat resistance over standard PLA. These grades can be used as neat resin or as part of a compound in order to further optimize overall material properties. In order to obtain improved heat resistance over standard PLA, these resins need to crystallize during processing. Luminy® D070, when combined with PLA homopolymers, will yield a compound that combines good heat resistance with excellent mechanical properties and a reduced processing cycle time.

Stereochemical purity: min. 99% D-isomer using Total Corbion PLA method

Biobased content: Luminy® D070 has a biobased content of 100% (confidence level 1) and a biobased carbon content of 100% according to EN 16785-1 under certificate number DIC-00001. Luminy® D070 is certified 100% biobased according to ASTM D6866 under the USDA Biopreferred program.

This material data has been provided by Total Corbion.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.

FOOD CONTACT STATUS: In the European Union, Luminy® PDLA polymers are compliant with EU commission regulation 10/2011 of 14 January 2011 (and amendments) on plastic materials and articles intended to come into contact with food. Lactic acid is considered a dual use substance, since lactic acid is approved as a food additive (additive number E270). There are no SMLs or SML(T)s for the ingredients used to produce Luminy® PDLA. The regulation does include an migration limit of 10 mg/dm2 on the overall migration from finished plastic articles into food. It is the responsibility of the manufacturer of the final product, when intended as a food contact product, to determine that the use of the product is safe and also suitable for the intended application. While it is Total Corbion PLA’s conclusion that the above mentioned polymers are permitted, it is the final product which must meet the given regulations and the manufacturer should take responsibility to check if the final product is in compliance with these regulations.

NOTICE REGARDING USE RESTRICTIONS: Unless specifically agreed to in writing, Total Corbion PLA will not knowingly market any product into any of the following commercial or developmental applications:

  • bottles or preforms, unless specific arrangements on recycling and end-of-life are in place
  • microbeads used in personal care products, including without limitation, cosmetics or over-the-counter drugs
  • components of products intended for human or animal consumption
  • any application that is intended to be used inside the human body.
  • Processing methods

    Extrusion: Melt blending of PLA homopolymers and Luminy® D070 can be done on conventional compounding extrusion equipment and can be used as neat resin or as part of a compound to further optimize overall material properties. A co-rotating twin-screw extruder with a minimum L/D ratio of 28 is preferred.

    Injection Molding: Melts of PLA homopolymers and 3–7% Luminy® D070 can be processed on conventional injection molding equipment using a hot mold of 90–110°C.

    MOISTURE & PRE-DRYING: It is recommended to dry Luminy® D070 from the packaging for 4-6 hours at 100°C. Drying of semi-crystalline PLA homopolymer can be performed in a desiccant hot air dryer, with a dew point of-40°C or less. It is recommended to reduce the moisture content before melt processing to a level less than 250ppm and preferably less than 100 ppm, measured by e.g. Karl-Fischer or Brabender aquatrac method. Predrying is in particular important prior to injection molding, film and sheet production. Moisture causes hydrolysis of the PLA homopolymer during melt processing, resulting in reduced mechanical performance in the final part.
