Plastic erasers, plastic bags, parts of projecting pencils{sometimes}...
Switches are made of plastic or bakelite because they don't conduct electricity.
I think is made out of hard plastic
Plastics are made from petroleum products.
Wood, Plastic.....
Yes, cling film is typically made out of polyethylene, which is a type of plastic. Polyethylene is popular for cling film production because it is flexible, transparent, and has good cling properties.
Cling film is typically made out of polyethylene, a plastic material that is flexible and can cling onto surfaces to create an airtight seal. Sometimes it may also contain other additives for specific properties such as heat resistance or stretchiness.
Saran wrap is sticky because it is made from a type of plastic called polyvinylidene chloride, which has adhesive properties to help it cling to surfaces and seal in freshness. This stickiness allows it to create an airtight seal when wrapped around food or containers.
Now are known hundreds types of plastic materials, different by chemical, physical and mechanical properties.
Plastic bottles Plastic bags Plastic utensils Plastic toys Plastic containers Plastic furniture Plastic packaging Plastic straws Plastic electronic devices Plastic car parts
Plastic reinforced by fibreglass, along with some plastic foam for certain parts of the boats.
Valve covers are typically made of plastic materials such as polypropylene or ABS (acrylonitrile butadiene styrene). These materials are chosen for their durability, heat resistance, and chemical resistance properties.
it's made of a certain amont of bug shells and hard plastic
Some fancier pens are made of certain types of metal.
Lead is a heavy metal that is dense and has toxic properties, while plastic foam is a lightweight material made from expanded polymers. Lead is harmful to health and the environment, while plastic foam is commonly used in packaging and insulation due to its lightweight and insulating properties.
Because the material properties are suitable, weight, springiness, slick surfaces, strength etc.
The material properties are suitable for the purpose,(color, shape, corrosion resistant....) and they're cheap to make.
