Wanhua Chemical has announced that it has developed a bio-based thermoplastic polyurethane product with a bio-content range up to 98 %. The company claimed that this is the world`s first TPU product that is made from 100 % biomass-sourced raw material.
The company said that the new TPU is processed from bio-based PDI derived from non-edible corn stalks; other materials are also from renewable resources like corn and castor seed. The new TPU is said to contribute to the green transformation in the fields of footwear, films, consumer electronics and food-contact, with its excellent properties in mechanical performance, flexibility and good resistance to oil and yellowing.
Wanhua Chemical has launched a series of TPU products in which the bio content proportion varies from 10 % to 98 %. The company said that in the future it will continue pursuing sustainability from the origins of the materials and strive to facilitate the low-carbon industrial chain alongside with both upstream and downstream partners.
