UPM Biochemicals’ Renewable Functional Fillers (RFF) are made from responsibly sourced hardwood from regional, sustainably managed forests. The new filler is a sustainable alternative to fossil-based and highly CO₂-intensive carbon black and silica., as well as other fillers. Currently, there are hardly any other similar fillers in accordance with sustainable development on the market.
Legislative requirements and consumer preferences for more environmentally friendly products are acting as drivers also within the rubber and plastics industry for replacing fossil-based materials with renewable alternatives. RFFs are suitable for a broad range of elastomers, TPE, TPV and plastics applications. They are perfect for automotive weatherstrip, hoses, seals, interior and exterior plastics parts, and other industrial rubber applications.
In addition to being environmentally friendly, RFFs are also recyclable. The color of polypropylenes that use RFFs remains stable from one recycling to another. The coloring pigment of the black plastic used in such products reflects near-infrared radiation (NIR), which can be identified during sorting.
– More than 94% of renewable carbon content
– Lightweight and features a lower material density of only 1.3 g/cm³ compared to the traditional fossil-based fillers used in the rubber and plastics industry
– 100% electrically non-conductive
– PAH-free product – no banned carcinogenic substances
– Meets the highest purity requirements
– Surface functionalities enable chemical bonding of RFF to polymer matrices
