BRISBANE (ICIS)--Thai MMA plans to shut its 90,000 tonne/year No 1 methyl methacrylate (MMA) line at Map Ta Phut for 10-14 days from July 10 on shortage of feedstock isobutylene, a company source said on Friday.

The company normally secures its raw material from Bangkok Synthetics (BST)’s 40,000 tonne/year C4 raffinate (isobutylene) unit in Map Ta Phut. The C4 raffinate plant, along with all the other plants of BST and its affiliate BST Elastomers, was shut on 5 May following a blast at the site.

Thai MMA’s No 1 line is currently running at 60-70% of capacity, while its No 2 line with the same 90,000 tonne/year capacity is currently operating at 100%, the source said.

The company is a joint venture between Japan’s Mitsubishi Rayon Corp (MRC) and Thailand’s Siam Cement Group.

MMA is produced using a two-stage gas-phase oxidation of isobutylene to methacrylic acid, followed by esterification.
