The development of modification technology in the plastics industry promotes the rapid progress of the properties of PP modified plastics
Modified plastics is a plastics industry that involves a wide range of areas, high technology content and can create huge economic benefits. Its market potential value is very huge. The development of modification technology in the plastics industry will definitely promote the rapid progress of the properties of PP modified plastics.
Then PP modified plastic, as the name suggests, is to improve its performance and other aspects on the basis of PP raw materials, such as enhancing the impact resistance, elongation, flexibility and so on of PP materials. The specific modification of PP plastic raw materials can be divided into the following categories.
1. PP+stone powder or mica/borax: It is generally used to produce heat-resistant modified PP. Mainly used in the shell of small household appliances, such as iron, rice cooker shell, etc.;
2. PP + calcium carbonate: This modification is not actually called modification, because the addition of calcium carbonate is only a compatibilization, and there is no improvement in the physical properties of the material. On the contrary, the toughness and strength of the material are reduced. Fortunately, the processability and fluidity have little effect. , adding calcium carbonate is mainly to reduce costs.
3. PP+POE or EVA: This type of modification is mainly to enhance the toughness and impact resistance of PP, which can be used in sports equipment and auto parts (such as car bumpers).
4. PP + flame retardant: to enhance the flame retardancy of materials, mainly used in electrical accessories, instrumentation shells.
In recent decades, the consumption level of Chinese people has been greatly improved with the rapid economic growth. The consumption upgrade has brought China's automobile, construction and other industries into a period of rapid expansion and growth. With the continuous improvement of people's requirements for plastic performance, my country is becoming the world's largest potential market for modified plastics and the main driving force for demand growth. We all know that ordinary plastics often have their own characteristics and defects. The performance of PP modified plastics is to change their properties for plastics. The modified plastic parts can not only achieve the strength properties of some steels, but also have a series of advantages such as light weight, rich colors, and easy molding.
