Plasticizing effect
WebbIn terms of plasticizing effect comparison, it should be highlighted that this effect is determined by a quantitative dosage of the fluxing agent added and is not influenced by a qualitative composition - paste, mortar, or concrete mix. That means that developed modifiers increase the flowability of cement pastes, cement mortars, and concrete ... Webb26 nov. 2024 · These products exibit lower volatility, high thermal resistance, lower plasticizing effect compared to arylphosphates or alkylphosphates. 10-15 phr are generally needed to pass traditional FR test. At lower levels RDP can improve the processability in thin wall injection molding of ABS and styrenics.
