Biofillers

Based on 24 products - Last update on the Jun 26, 2025

Biofillers are natural additives used in plastics to improve their mechanical and thermal properties, making them more durable and heat-resistant. These additives typically appear as fine powders or granules derived from agricultural or industrial by-products like rice hulls, coffee chaff, or wood fibers. Key features include their ability to reduce the carbon footprint of plastic products, enhance biodegradability, and provide cost-effective alternatives to traditional fillers. Used in packaging, automotive parts, consumer goods, and construction materials. 

Alternatives include traditional mineral fillers like calcium carbonate and talc. Sub-types include cellulose-based and starch-based fillers.

UPM Circular Renewable Black™

by UPM

UPM Circular Renewable Black™ by UPM is a renewable, detectable, bio-based functional filler in rubber and thermoplastic compounds. It offers excellent thermal stability during recycling confirmed by melt flow index (MFI) and oxidation induction time (OIT). It provides significantly improved carbon footprint of masterbatch compared to masterbatches using fossil additives and pigments. <br> <ul style="padding-left: 40px;"><li>It allows for NIR detectability of the base polymer, thus enabling sorting and recycling of black-colored plastic products.</li><li>It is made from certified feedstock from sustainably managed forests under FSC™ and PEFC, reducing dependence on fossil resources. </li> <li>It provides premium asthetics, transparency ensured through ISCC+ certification and an independent life cycle assessment conducted according to ISO 14040/44 standards. </li> <li>UPM Circular Renewable Black™ has an outstanding climate performance with a negative carbon footprint from cradle-to-gate considering biogenic carbon. </li> <li>It provides deep, rich black coloration that meets the highest standards for luxury packaging and premium products. </li></ul>

CHITOSAN Mw

by Chitelix

CHITOSAN Mw by Chitelix is a reinforcing filler or compatibilizer in bioplastics (e.g., PLA, starch-based systems), where its reactive amino groups allow covalent or ionic crosslinking within the polymer network. It is also used as an antimicrobial and antioxidant additive in packaging plastics. It offers bio-adhesive and film-forming properties. It is a natural polysaccharide obtained through the deacetylation of chitin derived from marine crustacean shells. It is produced through a sustainable circular approach. <br><ul style="padding-left: 40px;"> <li> CHITOSAN Mw is characterized by enhanced solubility and high reactivity, enabling efficient performance in formulations. </li></ul>
