In formulation design, the form of additives has a significant impact on modification. For example, fibrous additives provide good reinforcement, while spherical additives offer better toughening, flowability, and gloss.
Smaller particle sizes of additives result in better mechanical properties, color strength, and electrical conductivity, but reduced monodispersity. The form of the additive must be comprehensively considered to determine its dosage and surface treatment method.
Plastic modification technology improves plastic properties through physical modification methods such as filling, reinforcement, and blending during processing; chemical modification methods such as block copolymerization and radiation crosslinking; or other modification methods such as foaming, stretching, and compounding.
This technology can improve properties such as flame retardancy, thermal conductivity, mechanical properties, abrasion resistance, and electromagnetic shielding, but may lead to a decrease in gloss. Appropriate formulation is needed to mitigate these negative changes.
