Final answer:
Expanded plastics are used in packaging materials, insulation, disposable containers, and automotive components. They are versatile, lightweight, and recyclable, making them popular in various industries.
Step-by-step explanation:
Expanded plastics have a wide array of applications due to their lightweight, cost-effective, and versatile nature. Here are four broad product uses of expanded plastics:
- Packaging materials such as foam peanuts, bubble wrap, and protective casings for electronics and toys.
- Insulation in buildings for energy efficiency and in appliances such as refrigerators.
- Disposable containers including take-out trays, disposable cups, plates, and cutlery.
- Automotive components such as instrument panels, headlamps, and interior trim.
Beyond these uses, expanded plastics also form components such as beverage bottles, baby milk bottles, and for non-packaging uses like compact discs and protective riot shields. Recycling programs have also been established to tackle the issue of plastic waste, working towards reusing plastics found in yogurt tubs, vending cups, and egg cartons.
