The effects of nano-sized carbon black (CB). ammonium polyphosphate (APP). and microcrystalline cellulose (MCC) were tested relative to the mechanical and thermal properties of polypropylene (PP)-based composites. Composites were produced by injection molding in nine different combinations by adding materials at the levels of 0% or 10% MCC. https://thebrickes.shop/product-category/plant-stands/
