masterbatch<br />

The amount <strong>of</strong> plastic product generation cont<strong>in</strong>uously decreased s<strong>in</strong>ce 2005 until 2011<br />

compared to 2002. On the other hand, the amount <strong>of</strong> virg<strong>in</strong> material used (masterbatch)<br />

<strong>in</strong>creased s<strong>in</strong>ce 2005 until 2011 compared to 2002. The masterbatch is produced from Thai<br />

petrochemical <strong>in</strong>dustry.<br />

The downstream products from the petrochemical factory are used as raw materials <strong>in</strong> the<br />

plastic <strong>in</strong>dustry such as HDPE, LDPE, PET, PVC, PP, PS/EPS, ABS/SAN, and<br />

thermosett<strong>in</strong>g res<strong>in</strong>s. Figure 4.4 and 4.5 present the percentage <strong>of</strong> each type <strong>of</strong> polymer<br />

From Figure 4.4, <strong>in</strong> 2008, the thermoplastic polymer which is highest used is PP (21%),<br />

and the next order <strong>of</strong> polymer used is HDPE (12%). These k<strong>in</strong>ds <strong>of</strong> polymers are usually<br />

used to produce the packag<strong>in</strong>g plastics e.g., bottle, microwavable wares, detergent<br />

packag<strong>in</strong>g, glasses or cups, and plastic bags and films. 10% <strong>of</strong> PVC is the third<br />

consumption to produce plastic furniture and pipes for construction and agriculture works.<br />

Other polymers <strong>in</strong>cludes both thermoplastic and thermosett<strong>in</strong>g such as epoxy glue, PC,<br />

PMMA, silicone, POM, melam<strong>in</strong>e, and nylon.
