TPU-Bio-based thermoplastic polyurethane materials

Bio-based thermoplastic polyurethane material, made of renewable materials (content of about 30%-70%). The performance and advantages are comparable to those of traditional petroleum-based thermoplastic polyurethane, and in some aspects even better. The hardness of this product ranges from 82A to 55D.

Application：

Power cord jacket material

Features：

chemical resistance, high temperature resistance, abrasion resistance, low density, low temperature toughness, UV resistance, hydrolysis resistance, renewable source, meet SGS, ROHS, TO10.0, etc.

Bio-based thermoplastic polyurethane (TPU) is a new type of environmentally friendly material. It uses renewable resources (such as corn, castor oil, cassava, etc.) as raw materials to partially or completely replace traditional petroleum-based raw materials, thereby reducing dependence on fossil fuels and reducing the carbon footprint of the product throughout its life cycle.

The characteristics of bio-based TPU include

Bio-based content: The bio-based content of bio-based TPU can be very high. For example, the TPU with a bio-based content of up to 97% developed by Korean scientists shows its great potential in environmental protection.

Performance: Bio-based TPU is comparable to petrochemical-based TPU in physical properties, with high strength, high toughness, oil resistance and anti-yellowing properties, suitable for various applications.

Application areas: Bio-based TPU can be used in many fields such as footwear, film, consumer electronics, food contact materials, etc., providing the same versatility as traditional TPU.

Environmental protection: Bio-based TPU reduces the impact on the environment during the production process and is a representative of sustainable development and green chemistry.

Biocompatibility: Some bio-based TPU grades, such as Texin® Rx, are also biocompatible and meet the needs of healthcare applications, such as the biocompatibility testing requirements of ISO 10993-1.

With the advancement of technology and the improvement of environmental awareness, the development and application of bio-based TPU are gradually increasing. For example, Wanhua Chemical has launched TPU products made of 100% bio-based raw materials. These products use bio-based pentamethylene diisocyanate (PDI) made from corn stalks, and the additives also come from renewable resources, showing the application potential of bio-based TPU in multiple fields。
