Bio-based TPU membrane

Under the trend of carbon neutrality, carbon peaking, and sustainable economic and social development, bio-based materials and markets are developing rapidly, so does bio-based TPU .

TPU , short of thermoplastic polyurethane , is a kind of new eco-friendly material , it is made to TPU membrane to replace of PVC membrane by many industries .

Bio-based TPU is partially made with renewable natural resources (such as corn, wheat,, etc.) ,but still maintains the same performance as traditional fossil based TPU. One of the most important renewable biomass technology is Susterra ® biomass from United States DuPont Tate & Lyle Bio Products ™ company .

The biomass 1 -3 propanediol which is extracted from corn was added to the TPU to replace part of the petroleum material . Susterra® propanediol is renewably sourced and generates up to 48% less greenhouse gas emissions cradle-to-gate compared to 1,4-butanediol (BDO), a common petro-chemical sourced alternative.
The benefits of Susterra® propanediol include:
Petroleum-free
Non-toxic and food safe
100% sustainably and renewably sourced
USDA 100% certified bio-based product

Susterra® propanediol can help companies fulfill their sustainability goals without compromising on quality across a variety of industrial applications. One of the most important application is bio-based TPU membrane.
Made by bio-based TPU via blowing , bio-based TPU membrane maintains properties of high performance of waterproof and moisture permeability , but also bio-degradable , it is chose by more and more industries such as outdoor garments , home textile , bags and shoes etc.
Till now , bio-based TPU membrane made by Nanxiong can meet clients’ different requests , you can choose different biomass content based on application .
