Assumption and Calculation
This amount was estimated by considering the growth rate of imported thermoplastic
pellets. The amount of imported thermoplastic will increase by 13% in 2016
300,000 Assumed that 300,000 tonnes of imported thermosetting pellets in 2016.

The estimation of thermoplastic raw materials was done by considering the growth rate of
total pellet consumption. The amount of plastic pellet consumption will increase by 3% for
each year. The amount of thermoplastic material consumption must be deducted by
thermosetting material consumption before filling in the material flow.
The estimation of thermosetting raw materials was done by considering the growth rate of
total pellet consumption. The amount of plastic pellet consumption will increase by 3% in
2016. The amount of thermosetting material consumption will increase by 8% in 2016.
This amount was estimated by considering the growth rate of exported products. The
amount of exported products will increase by 4% in 2016. The estimated amounts of
imported and exported plastic products are shown in Table E-4 in Appendix E.
90% of raw material (Masterbatch) and imported pellets will be changed into plastic
products in 2016. (but it was deducted by the amount of exported product before put in the
material flow)
90% of raw material (Masterbatch) and imported pellets will be changed into plastic
products in 2016. Assumed that it is not imported and exported
