HOUSTON (ICIS)--Naphtha-based ethylene margins in Asia rose on weaker feedstock costs during the week ended 16 September, while LPG-based ethylene margins fell on weaker spot prices, the ICIS margin report showed on Monday.
In Northeast Asia, naphtha-based ethylene margins rose by 2.2% to $843/tonne, while margins in Southeast Asia rose by 2.5% to $740/tonne.
Feedstock costs for ethylene production were down in each region, by $39/tonne and $40/tonne, respectively, for NE Asia and SE Asia.

For LPG-based ethylene, margins in NE Asia fell by 1.7% to $830/tonne, and margins in SE Asia fell by 2.5% to $692/tonne.
