Typical natural oil price is about £300-320 per tonne, and this has been fairly stable over many years," Colvin continued, it costs about £100 per tonne to convert so, with petrochemical polyols at about £1000 per tonne, the level of savings can be useful."Our web edition, available to subscribers at www.urethanestechnology.co.uk, does not have this defect.Apologies to all concerned for any difficulties this glitch might have caused.David Reed, Editor Urethanes Technology magazine"
