When the whisker is mixed with PP, it can change the crystallization behavior of PP, and has obvious strengthening effect.
Examples of toughening modification formula.
PP/PE toughening system The toughening effect of LDPE on PP is obvious, but other mechanical properties such as flexural modulus decrease rapidly. When the content of HDPE in PP is less than 10%, it has a rigid toughening effect on PP, that is, while increasing the impact property, other mechanical
Design Examples of Inorganic Rigid Particles Toughening Formula : PP + calcium carbonate/ kaolin/ Precipitation BaSO4/ Nanofiller/ Alkali earth metal salt.
Matters needing attention in the design of toughening formula: 1.The compatibility between elastomer and resin should be good. 2. Compatibilizer 3. Synergistic effect of elastomer 4. Other factors to be considered 5. Rigidity compensation
