This thermoplastic polymer is strong, lightweight, and versatile, with excellent resistance to many chemicals and high durability. Available in two main variants\u2014homopolymer (PPH) and copolymer (PPC)\u2014it can be enhanced with mineral fillers for applications requiring robustness and durability, and is offered in natural, black, or custom-colored versions.<\/p>\n
Regenerated polypropylene has physical properties similar to virgin polymer, ensuring the same processability for injection molding and extrusion applications.<\/p>\n<\/div><\/div><\/div>
