Rheology Modifiers for Recycled Polymers
Rheology Modifiers for Recycled Polymers Rheology Modifiers help manufacturers control melt flow and processing behavior in polymer compounds containing high levels of recycled plastic. Because post-consumer recycled (PCR) and post-industrial recycled (PIR) materials can vary in molecular weight, contamination, moisture, and thermal history, their processing behavior may be less predictable than that of virgin polymers. […]
Functional Fillers in Polymer Compounds
Functional Fillers in Polymer Compounds: More Than Cost Reduction Functional Fillers are incorporated into polymer compounds to modify properties such as stiffness, dimensional stability, thermal behavior, surface finish, and processing performance. Although fillers can reduce the amount of more expensive base resin in a formulation, their technical value depends on filler chemistry, particle shape, surface […]
Chain Extenders for Recycled Polyolefins
5 Key Roles of Chain Extenders in Recycled Polyolefins Chain Extenders are reactive additives used in selected polymer systems to modify molecular structure, melt behavior, and processing performance. In recycled polyethylene (PE) and polypropylene (PP), their effectiveness depends on the chemistry of the additive and the condition of the recycled resin. Because polyolefins behave differently […]
