2. Raw Materials of Plastics
 Plastics are derived
from organic products.
The materials used in
the production of
plastics are natural
products such as
cellulose, coal, natural
gas, salt and crude oil.

3. Classification of Plastics
 2 distinct groups: thermoplastics & thermosets
Polyethylene (PE) family: LDPE, LLDPE & HDPE

4. History
 Fawcett & Gibson accidently produced LDPE (linear
low-density polyethylene) by doing an experiment in
1933.
 HDPE (high-density polyethylene) was discovered by
Zigler & Natta in 1950s
 LLDPE (Linear low-density polyethylene) was
discovered later in 1980s

5. PE Application - LDPE

6. PE Application - LLDPE

7. PE Application - HDPE

8. Differentiation of Original &
Recycle HDPE Plastics
 Uneven colors
 Smells chemical
 Surface roughness
