Modified PP Resins

# We sell plastic raw material # Modified PP Resins

In response to the poor impact resistance at low temperatures, poor weather resistance, poor surface decorative properties, and the gap between the functionality of polypropylene in electricity, magnetism, light, heat, and combustion, and the actual needs, Modified PP Resins has become the most active and fruitful area of plastic processing development.

PP Physical Modification

In the mixing and blending process, organic or inorganic additives are added to the PP (polypropylene) matrix to obtain PP composites with excellent performance, mainly including: filling modification, blending modification, etc.

• Blend modification

PP (polypropylene) is blended with polyethylene, engineering plastics, thermoplastic elastomers or rubber to achieve the modification method of improving the performance of PP. Blending modification is done in processing equipment such as compactor, opener, extruder, etc. The process is easy to regulate, short production cycle, low cost, and can improve the colorability, processability, anti-static, impact resistance and other properties of PP. Polymer blending can synthesize the outstanding performance of each component and make up for the deficiencies in the performance of each component, and the overall performance of the blends is obviously improved, but the low temperature resistance and aging resistance of the blended modified PP are still not very good. Blending modification, shear force may lead to part of the macromolecular chain is cut off to form free radicals and form graft or block copolymers, these new copolymers can also effectively play a capacitating effect on PP.

PP modification technology makes the mechanical properties of composite materials to be improved exponentially, which greatly expands the application field of PP, improves the cost performance of products, promotes the engineering process of PP, and also makes PP expand from general-purpose plastics to engineering plastics, which greatly broadens its application scope. In recent years, the research of PP modification technology is developing rapidly, and more and more new technologies are applied to PP modification, so that the comprehensive performance of PP is improved obviously and the application field is expanded continuously, and the development prospect is very broad.
