Application of polypropylene modified material
Application of polypropylene modified material :
Polypropylene as one of the four universal plastic materials, has excellent comprehensive performance, good chemical stability, good molding performance and relatively low price; But there are also low strength, modulus, hardness, low temperature impact strength, forming shrinkage, easy aging and other shortcomings.
Therefore, modification is needed to meet the needs of the product. PP material modification is generally used to add minerals to strengthen, weather resistance modification, glass fiber strengthening, flame retardant modification and super tough modification and other methods, each modified PP has a lot of applications in the field of home appliances.
Modified PP has a good application prospect in home appliance industry. On the other hand, China has become the world's center of consumer electronics production, with influential manufacturers who can actively select materials. On the other hand, industry competition is pushing companies to use more cost-effective materials.
From the perspective of future home appliance technology development, home appliance humanization is more prominent, product types are more perfect, and traditional home appliance will develop to miniaturization and scale. With the emergence of new products, the demand for PP is increasing. There are four main trends in modified PP:
1, high hardness, high gloss PP. This kind of product may replace some household appliances, especially small household appliances PS and ABS.
2, halogen-free flame retardant PP. With the implementation of RoHS directive, all countries attach great importance to environmental protection, and there is an urgent need to research and develop halogen-free flame retardant PPP, which has a broad market prospect.
3, long glass fiber reinforced PP. Ordinary short glass fiber reinforced PP containing glass fiber short, easy warping, low impact strength, easy deformation when heating, long glass fiber can overcome the shortcomings of short glass fiber and product surface. Good temperature, impact strength, heat resistance, can be used in refrigerators and kitchen appliances.
4, antibacterial PP. The plastic is a new functional polymer material with bactericidal and antibacterial properties, which is used in the plastic parts of washing machine liner and electric water tank, and has broad prospects.
