Engineering plastics can be modified by physical, chemical or physical and chemical methods, including blending (alloying), copolymerization (grafting) and filling reinforcement.

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

antistatic automotive PP materials have become one of the important directions in the field of plastic modification.

PVC/TPU Blending 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.
