- Lego is made out of ABS (Acrylonitrile Butadiene Styrene).
-This is useful because it can be easily made by an injection moulding process.
-Because of this process, it is even more great as all the products produced with a certain mould will be the same. - ABS is a very durable product and would withstand things like colliding with each other or being thrown about.
-Also is not toxic as it is used for children, however restricted to ages 3 years or older because of small parts. - ABS is also used because it doesn't trigger any allergies.

CD's:
- CD's are made by using injection moulding. This is great because no material is wasted.
- Because they are made out of PC, they are temperature and impact resistant.
Hard hats:
- Hard hats are made out of HDPE today, because they're easy to to mold and shape and costs less to manufacture.
- Made by injection moulding.
- HDPE is used because it's very impact resistant and protects people from sharp objects penetrating through the hat and also distributes impact shock from things falling on top over a larger surface area to cause less of an impact at one point.
Plumbing & Guttering pipes:
- Most commonly produced with PVC (Polyvinyl chloride) as it has a relatively low cost. And easy to work with and has biological/chemical resistance.
- It can become flexible when plasticizers are added to it.
Eyeglass frames:- Some glasses have their frames made out of CA (Cellulose Acetate).
- CA has many properties for use of a product like this such as:
-Soft/smooth/resilient.
-Comfort, no static clings.
-Deep shades in colour.
-Lustrous. - Eyeglass frames like this are made using a die-cutting process.

Tupperware:
- Tupperware can be made out of PP (Polypropylene) as it's a very impact resistant material and also flexible.
- PP is also great because it's easy to clean with a dishwasher/hand-washing and it doesn't attract any bacteria/microbes.
