(Tonnes/year)
Assumption and Calculation
Manufacturing process
1 Imported pellet (Thermoplastic) 1,491,446
This amount was estimated by considering the growth rate of imported thermoplastic
pellets. The amount of imported thermoplastic will increase by 13% in 2016
2 Imported pellet (Thermosetting) 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
3 Raw material (Thermoplastic) 3,721,094 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
4 Raw material (Thermosetting) 430,513
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.
5 Stock in manufacturing 137,390
The amount of plastic pellet was stocked in country. Assumed that the amount of
stocked in manufacturing will be the same in 2010.
6 Calculated stock by STAN -18,841 Stock = input of process - output of process
This amount was estimated by considering the growth rate of exported products. The
7 Exported product 1,141,864 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
8 Plastic product (Thermoplastic) 3,549,422 products in 2016. (but it was deducted by the amount of exported product before put
in the material flow)
