Level of glass fiber reinforced, flame retardant polypropylene in electrical aspects can be used for electrical switch, junction box, electronic parts, distributor cap, electric tools and other electrical components and electrical equipment, special grade copper resistance, electromagnetic interference shielding.
Injection molding processing parts with weatherability aspects requirements can choose PP/polypropylene alloy and PP/SMA.
High impact of elastomer toughening PP used for car bumper material, provides a good safe performance car.
As a result, 95% of cars in Europe bumper material using the material.
PP and often with some engineering plastics, by compatilizer technology preparation of alloys, such as PA, PC, PET, PPO and UHMWPE. Recently developed the direct preparation of alloy in the reactor technology, can improve the strength, rigidity, dimensional stability and heat resistance. Mixed to mix some polar polymer, and can improve the printing, adhesive and as auto parts material coating. The crosslinking technology can improve the mechanical properties and thermal properties of PP.
hinge properties of PP in box, hood, container cover has got a lot of application, cover and a box body or the bottle shape, both reduces the cost, and brings convenience to use, can be used for stationery, and meter boxes, tool boxes, glasses boxes, cosmetics, etc. The application of PP in rigid package including turnover box, beer preservation barrels of the shell, tray, carrying vessel, blow molding bottle and the production of thermal forming container.
has developed a kind of crosslinked PP, can improve the heat resistance of 20 - 30 ℃, creep resistance increase 105 - 5. 0 times, abrasion resistance, oil resistance, low temperature characteristics also have greatly improved, such as adding nucleating agent, can spur PP crystallization, grain structure ultra-micronization model. the, nucleating agent type is more, different types of nucleation effect of nucleating agent is different, some can improve the comprehensive mechanical properties, while others focus on transparency.
good physical properties and relatively low price, make the PP has a very wide range of applications, involving areas such as automobiles, household appliances, packaging, machinery, home appliances, supplies, etc. PP in auto plastic occupy the largest share, accounting for about 42% of the total market, a lot of inner decoration and outside decoration such as bumper, dashboard, etc. , the use of visual components requirements can choose high impact, high rigidity, high heat resistance, high gloss and other brands. Most of plastic alloy and mixing. Some inner decoration can use high crystalline PP directly.
the commonly used filler calcium carbonate, talc, mica, adding quantity can reach 50%, the current trend in refining, inorganic filler with nanoscale inorganic particles modified PP, has satisfactory effect in terms of rigidity and toughness, and can improve the thermal stability. Add rubber, thermoplastic elastomer and other flexible polymer can greatly improve the impact toughness, depending on the different rubber content, can be in the preparation, high impact, high impact and three kinds of high impact PP injection molding processing, but the heat resistance, rigidity to decline. In this type of blend and then adding glass fiber and inorganic filler, in order to maintain the balance of the various performance.
home appliance applications is given priority to with plank and injection molded parts, main application has a washing machine, dishwasher, dryer, refrigerator, TV, air conditioning, also include some small home appliance, need some special brand, such as within the barrel of washing machine parts. High quality PP can compete in this area with ABS. Random copolymer of PP and the transparent polypropylene developed into nuclear technology, the transparency is 96%, which can reach 89%, with typical transparent material, such as PET, PVC, PC, high transparency can be widely used in food containers, stationery and need to be used under high temperature or disinfection equipment, such as baby bottles, drink cups, some must be resistant to radiation levels of PP.
