Bio-Filler Compounds

Asahi Kasei's elastomers enable the creation of bio-filler compounds that are highly filled yet flexible, contributing to plastic reduction efforts.

Utilization in Bio-Filler Compounds

Plastic Reduction with
Bio-Fillers

As part of environmental initiatives, efforts to reduce plastic usage by highly filling with bio-fillers are gaining attention. While bio-filler compounds generally face challenges in terms of bending and impact resistance, Asahi Kasei's TUFTEC™ can be used as a compatibilizer to produce flexible compounded products. It is also expected to be effective in compatibilizing wood powder, starch, bamboo flour, and paper pulp.

TUFTEC™ for Compatibilizing Bio-Fillers with Plastics

Wood powder typically undergoes a change in properties at temperatures exceeding 230°C, making it suitable for use as a compounding raw material only with olefin-based or styrenic plastics having a melting point below 200°C. However, due to the high polarity of wood powder and the hydrophobic nature of plastics, these two materials are incompatible and difficult to mix.

TUFTEC™︎ M series is the optimal solution to this challenge. The acid-modified portion of TUFTEC™ interacts with the polar groups on the surface of wood powder, enhancing the affinity between wood powder and plastic and enabling mixing.

By incorporating TUFTEC™ M series into low-polarity resins like polyolefins, the functional groups on the surface of bio-fillers interact, resulting in improved filler dispersion.

Significantly Improving the Performance of Bio-Filler Compounds

Previously, bio-filler compounds suffered from weaknesses in bending and impact resistance, making them impractical for use as material in products.

TUFTEC™ M series exhibits affinity with both bio-fillers and plastics. When added as a compatibilizer, it significantly enhances the impact resistance of the compound, imparts toughness, and improves flexibility and ductility. This enables the application of the material in a wide range of products.

The incorporation of TUFTEC™ improves various mechanical properties and enables improved flexibility.
