The application of foam PP in the automotive field
After the 1990s, countries have placed more emphasis on lightweight, pollution-free, and recyclable aspects in the selection of automotive materials
Comprehensive performance provides new opportunities and markets for the expanded application of polypropylene foam in automobiles. By 1996, there were 63 species in the United States, including 19 GM species, 13 Chrysler species, and 8 Ford species; there were 25 species in Europe, including 3 Mercedes-Benz species, 5 Volkswagen species, and 25 species in Europe.
There are 6 types of Bao; there are 57 types in Japan, including 17 types of Nissan, 15 types of Toyota, and 16 types of Honda. At present, some domestically produced models also use foamed PP, such as Shanghai Volkswagen Passat, FAW-Volkswagen's Jetta, Bora, and Audi, and Tianjin FAW Toyota's Crown and Vechi.
Tianjin FAW's Ville, Xiali 2000, Venza, GM's Chevrolet SUV, Buick GL8, Shenlong's Fukang, Peugeot 307, Elysee, Beijing's Cherokee, Outlander and other models.
In addition to high heat resistance, high impact energy absorption, good resilience and thermoformability, PP foam also has the advantage of being recycled
Used in manufacturing automobile parts, such as steering wheels, trim panels, floor panels, side guards, air-conditioning vapor barrier panels, exterior armor panels, door inner panel energy-absorbing protective pads, cushioning pads, and shock-proof panels (cushions), headrests, seat backs, tool boxes, instrument boxes, control boxes, automobile I'-J water-proof layers or sound insulation panels, spare tire covers, battery casings, engine covers and Luxury car rear engine compartment
Engine compartment. In areas that require higher operating temperatures, polypropylene foam is more advantageous than polyethylene foam, such as sun visors, insulation panels on instruments
and two cars. I'-If the temperature is easy to rise In addition, inserts for sound attenuation and insulation materials, shock absorber core materials and damping materials can also be manufactured.
(1) Automotive interior decoration materials
Automotive interior decoration materials usually use laminates composed of PP (core material), foamed PU (cushioning material), and PVC (skin) Material
Material. Mitsui Petrochemical Company's patent proposes to laminate cross-linked foamed PP with skin materials and cushioning materials to manufacture interior decoration materials for carports and doors.
