Legos, rulers, bottles, toys, etc.
Many plastics are.
The difference between plastics and elastomers is actually quite simple. Plastics are made from oil and elastomers are made from synthetic material.
No, not all plastics are petrochemicals. A few examples of bioplastics (plastics made from biologic sources) include Polyhydroxyalkanoates, Polylactic Acids and a wider variety of starch based plastics.
Many parapharmaceutical products are made from plastics.
- Some plastics made from starch are biodegradable- Another bio-oxodegradable plastics contain a catalyst ( as iron oxide) which improve the degradation in contact with oxygen.Generally biodegradable plastics are as foils not containers.
theyre made out of cheap plastics
A drill is made of steel and plastics
They are made all over the world.
Plastics and metals
yes
There are two types of biodegradable plastics: bioplastics and plastics made from petrochemicals. Bioplastics are made from renewable resources, like vegetable fats and oils, vegetable starch, or microbiota. Plastics made from petrochemicals are made by combining biodegradable additives which enhance biodegradation.
Two of the earliest plastics were:Bakelite = phenol formaldehydePolyurethane = urea formaldehyde
