Acrylonitrile-butadiene-styrene (ABS) (see chapter 7.1.3). 
 
Polyacrylonitrile (PAN) is a semi-crystalline polymer resin. Though it is 
thermoplastic, it does not melt under normal conditions. It degrades before 
melting. It is used to produce large variety of products including ultra-filtration 
membranes, hollow fibers for reverse osmosis, fibers for textiles, and PAN 
fibers that are the chemical precursor of carbon fiber. 
 
Cumene is an aromatic derived from benzene and is used in turn to produce 
polycarbonates, phenolic resins and essential healthcare products such as 
aspirin and penicillin.
