Problems solved by technology

However, in the preparation process of PP modified materials, in order to achieve the required performance of the product, it is often necessary to add some mineral fillers, glass fibers, grafts, coupling agents, lubricants, stabilizers and other auxiliary materials. It may bring some obvious abnormal smells. During the synthesis process, the small molecules that are not fully polymerized are not completely eliminated, and there will also be some obvious smells, especially some powdery PP smells are more obvious.
[0003] At present, the domestic method to solve this problem is basically to remove small odor molecules by vacuuming during the extrusion and granulation process, but the effect is not good and cannot meet higher requirements
Some companies solve it by adding a small amount of odor masking agent, which does not really solve the odor problem, but brings other odors
[0004] In addition, maleic anhydride is most commonly used as a compatibilizer in the production process of PP, which has certain toxicity. Since children are very sensitive to odors and toxic compounds, PP produced with maleic anhydride as a compatibilizer is not suitable for children's products. make
[0005] Although PP products have the characteristics of excellent mechanical properties, chemical corrosion resistance and easy processing and molding, their toughness is poor, their tensile properties and impact properties are average, and they are brittle, especially when they are placed in sunlight and exposed to ultraviolet rays, etc. impact, more brittle
