About Solid Plant
Solid Plant GmbH, based in Monheim am Rhein, develops and produces the bio-based filler HEMPLIZIT®, manufactured from micronized hemp shives, a side stream of fibre processing. The material is used as a co-filler alongside carbon black and silica in elastomers, thermoplastics, paints and coatings, adhesives and sealants, and construction materials. With a density of around 0.98 kg/l, it significantly reduces the filler mass at the same volume. Two product lines (HPE30 for elastomer compounds with high demands on dispersion and dynamics, HPE50 for volume- and cost-oriented applications) cover different compound requirements. In addition to material production, the company offers application engineering support for compound incorporation, mill certificates for every delivery, laboratory samples and pilot quantities, as well as the formulation software RAWCIPE®. Distribution in the EU is handled by Biesterfeld; HEMPLIZIT® is exempt from REACH registration (Annex V) as a non-chemically modified natural substance.

Materials and Processes
HEMPLIZIT® HPE30
Micronized hemp shives as a co-filler for elastomer compounds with high demands on dispersion and dynamics; tested in the tire compound study of the University of Twente alongside carbon black N330.
HEMPLIZIT® HPE50
Micronized hemp shives for applications in which volume, weight and cost-effectiveness of the filler content are the priority.
Natural rubber (NR)
Independently verified matrix for the use of HEMPLIZIT® as a co-filler.
SBR
Independently verified matrix for the use of HEMPLIZIT® as a co-filler.
EPDM
Independently verified matrix for the use of HEMPLIZIT® as a co-filler.
NBR
Independently verified matrix for the use of HEMPLIZIT® as a co-filler.
Butyl rubber
Independently verified matrix for the use of HEMPLIZIT® as a co-filler.
Thermoplastics
Compounds and masterbatches in which weight and bio-based content matter.
Carbon Black N330
Established filler that can be partially supplemented on a volume-equivalent basis with HEMPLIZIT®.
Silica
Established mineral filler that is supplemented rather than replaced by HEMPLIZIT®.
