6. Can Sorona be recycled?

Yes, Sorona is recyclable, meaning that it can be reduced back to its original composition. At the same time, Sorona can also use polyester recycling process for recycling.

7. What can prove that Sorona is not entirely from oil?

Sorona is not entirely derived from petrochemical feedstocks because "ancient" petrochemical feedstock ingredients and "young" biomass feedstock ingredients can be easily separated by measuring the carbon age in Sorona polymers. According to the ASTM D6866 test standard, both Beta laboratories and SGS in the United States all certify that 28% of the biomass carbon in Sorona polymers is certified. For details, please refer to the contents of "Environmental Information".

8. What is the chemical name of Sorona polymers?

Sorona's chemical name is: Polytrimethylene terephthalate (PTT for short)

9. What Sorona uses raw materials derived from renewable resources?

Sorona is a polymer ---- "polymerization" means more than one raw material component. Sorona requires two ingredients to produce. The main ingredient - bio-based PDO (bio-based 1,3-propanediol) is obtained using a process of sugar fermentation (similar to making beer). The sugar currently used comes from corn. The future may use other sugary crops, such as sugar cane, cassava and sugar beet. The bio-based PDO product was manufactured by DuPont Tatelite Biological Products Ltd., a Equestrian Equity joint venture based in Dayton, Tenn., USA.

10. Where can I buy the fiber or fabric made of Sorona?

DuPont manufactures and markets Sorona polymers. We have complete downstream customer resources in Asia, especially China, Taiwan, South Korea, etc., including our customers for fabrics and fabrics. DuPont does not sell fiber or fabric.
