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
antistatic automotive PP materials have become one of the important directions in the field of plastic modification.
The blend of PVC and ABS can combine the advantages of the two and become a new type of material with wide application in electric housing, electrical components, automobile dashboard, textile equipment, luggage and so on.
Rigid PVC/EVA blends can be used to produce plates and profiles, or to produce low-foamed products. Soft PVC/EVA blends can be used in the production of cold resistant film, sheet, artificial leather, and also used in the production of foaming products.
Improve the impact strength of PVC and the processability of PVC. Widely used in toughening and modification of rigid PVC, especially in transparent products.
CPE can act as a compatibilizer between PVC and PE and can improve the properties of the blends. It is of great significance for the recycle and reuse of PVC and PE recycled plastics.
The main methods of modification are chemical modification, filling modification, strengthening modification, blending modification and nanocomposite modification.
In fact, any plastic raw material has at least a certain proportion of stabilizers when it leaves the factory to prevent it from degrading in storage, transportation and processing. Therefore, strictly speaking, "unmodified plastics" do not exist. In industry, basic resins produced by chemical plants are commonly called "unmodified plastics" or "pure resins".
Blending modification refers to the blending of other plastics, rubber, or thermoplastic elastomers with PP and filling them into larger crystal spheres in PP to improve the toughness and low temperature brittleness of PP.
