Asia’s paraxylene (PX) should closely track upstream crude and naphtha values. The Asian orthoxylene (OX) spot market will be volatile in the 2015 second quarter (Q2) due to reduced supply from an explosion at a Chinese plant in April. Weak market conditions in the derivative plasticizer sector, coupled with high production cost, might encourage downstream phthalic anhydride (PA) makers to target reduced operating rates, turning OX demand sluggish.
