Biofillers for Plastic Compounds

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.

• It allows for NIR detectability of the base polymer, thus enabling sorting and recycling of black-colored plastic products.
• It is made from certified feedstock from sustainably managed forests under FSC™ and PEFC, reducing dependence on fossil resources.
• It provides premium asthetics, transparency ensured through ISCC+ certification and an independent life cycle assessment conducted according to ISO 14040/44 standards.
• UPM Circular Renewable Black™ has an outstanding climate performance with a negative carbon footprint from cradle-to-gate considering biogenic carbon.
• It provides deep, rich black coloration that meets the highest standards for luxury packaging and premium products.

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.

• CHITOSAN Mw is characterized by enhanced solubility and high reactivity, enabling efficient performance in formulations.

CHITOSAN Hw 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, film-forming and antimicrobial 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.

• CHITOSAN Hw is characterized by enhanced solubility, high viscosity, and high reactivity, enabling efficient performance in formulations.

NaturFil™ Pine Wood Flour Concentrate by Lignetics is a sustainable and biodegradable filler designed for use in rigid and semi-rigid polymer composites. It is derived from finely ground natural wood fibers and provides an eco-friendly alternative to traditional mineral fillers. It is suitable for wide range of thermoplastics, including polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), and acrylonitrile butadiene styrene (ABS).

• Produced with patent-pending technology, it is densified to improve feedability and handling compared to traditional wood flour.
• It enhances stiffness and dimensional stability of polymer composites.
• It reduces overall material cost and adds a natural aesthetic.
• It has added bio-content with less dust, and faster processing speeds vs. traditional wood flour.
• It is suitable for injection molding, extrusion, and compounding processes.
• NaturFil™ Pine Wood Flour Concentrate is recommended for automotive, furniture, consumer goods, agricultural and horticulture, building and construction.

Santoweb® D by Lanxess is a treated cellulose fiber product that provides reinforcement for uncured and cured rubber compounds. It is designed for raw edge V-belt base compounds, low-pressure hoses, gaskets, diaphragms, and tire bead apex compounds.

• Increases product stiffness, green strength and reduces die swell, cold flow, and cut growth rate in rubber compounds. It also functions as a filler.
• Offers good bonding to the rubber matrix It does not cause compound staining.
• Santoweb® D should be used with a methylene donating chemical for applications in which adhesion of the fiber to the rubber matrix is critical.
• Santoweb® D shows compatibility with NR, SBR, BR, and CR. It contains 68% wood pulp and 32% SBR binder.
• The recommended dosage for improved green strength is at levels of 1-4% by weight, increased flexural stress at 5-15% by weight, and very significant fiber reinforcement at 10-20% by weight.

ARBOCEL® C 400 by JRS Rettenmaier is a beige colored, natural softwood product with a cubic structure. The main particle range is 205-600 µm. It is a sustainable material for various applications as fiber reinforcement and functional filler. It is also used as a thickener, as an absorbent and diluent or as a carrier.
