    Luoyang, Henan - Liming Institute is expecting to complete construction of its 20T/year dimeryl diisocyanate (DDI) facilities in mid or late 2015, the company said.

    "The DDI facilities are expected to have RMB6-10m ($1-1.6m) annual production value when in operation," said Shang Bingkun, head of the institute's propellant R&D department. Both crude and refined DDI will be supplied.

    Development of such DDI material was finished in 2010 with RMB6m research expenditure. It was the first time such technology was developed by a Chinese company, according to Liming's website.

    The production adopts the hydrazine method with normal pressure and temperature. Plant oil is used as starting material and testing results show that the DDI produced has an oral LD50 value of more than 34g out of every kg in laboratory rats, less than 10% of other common diisocyanates.

    "Besides low toxicity, Liming's DDI is also odourless and bio-recyclable," said Shang. "It has lower water sensitivity and lower saturated vapour pressure compared with other aliphatic diisocyanates."

    "DDI can be used in fabric processing and the production of elastomer, adhesives, sealants and coatings. Low toxicity gives it great advantages over HDI and IPDI in areas like coatings," Shang added.
