glass microbeads in plastics
Application of glass microbeads in plastics
At present, microspheres are widely used in plastics processing industry. It is mainly manifested in the following aspects:
1 micro bead reinforced bumper special material
Automobile insurance materials are the most important plastic parts in the automotive industry. They require light weight and high impact resistance. Only a few units can produce.
At present, microbeads are used as filler and the new method of plastic modification is made of polypropylene resin as the main body, microbeads and various auxiliaries, modifiers, mixed with twin screw extruders, plasticizing, granulation, and production of special material for automobile bumper. This special material has excellent mechanical properties, excellent chemical stability and aging resistance. This kind of special material is the special material of all kinds of car bumpers, especially the high grade car bumper, and it can also be used to make the automobile fender, skirt panel, interior ornament, guide plate and so on, which require high impact resistance.
2 micro bead flame retardant special material
Because the bead itself is vitreous, it is flame retardant and high temperature resistant. Although the water can not be decomposed during the combustion, the organic - inorganic compound flame retardant system is used in combination with organic flame retardant, which not only maintains the mechanical strength of the plastic products, but also meets the requirements of the UL94V-0 standard in the United States.
As a result of the addition of microbeads and organic flame retardants, the plastic products can be used for a long time at high temperature and are suitable for various processing techniques. This special material can be widely used to produce various kinds of electrical appliances and other products that require flame retardancy.

3 microbead modified pipe material special material
Plastic pipes and plates made of various resins such as PP, PVC and ultra-high molecular weight polyethylene have been used in various fields. For high demand products such as large caliber natural gas pipes, oil pipes, and various water supply pipes, in order to improve weatherability, corrosion resistance, wear resistance, heat resistance and impact resistance, The best way to do it is to add the emblem.
To this end, researchers have developed PP, PVC, ultra high molecular weight polyethylene as carrier resin for micro bead modification special material. This special material shows excellent strengthening and toughening effect, with excellent impact resistance, heat resistance, low temperature resistance, wear resistance, corrosion resistance and weatherability.
4. other applications
For many plastic products, more bead modifier masterbatch and special materials can be developed. For example, for nylon (PA-6) products, the traditional practice of adding glass fiber to enhance the modification is very common, such as adding 30% fiberglass masterbatch into PA. Now using 25% beads and 5% glass fiber to make PA masterbatch, all properties can reach the original 30% fiberglass masterbatch index. However, the price of microbead filler is only half of that of glass fiber, and the cost of material is reduced. For example, the shuttle used for textile is often replaced because it is not wear resistant. Now the service life of plastic shuttle filled with microbeads has been greatly extended.
At present, the development and application of microsphere materials is the key to promote the development of microsphere materials. Surface modification, polymer materials science and application of composite materials are the key technologies. Only by strengthening the research in this area can microbeads materials play an important role in polymer materials and industries such as plastics and rubber. That is to say, inorganic powder materials can be developed into composite materials only when combined with polymer materials.
