CAS NO.107-21-1
APPLICATION:
1. The major end uses of ethylene glycol are as an anti-freezer and as raw material in the production of polyester fibers.
2. Coolant and heat transfer agent
3. Ethylene glycol is a useful desiccant for its attribute of high boiling point and affinity for water.
4. Niche applications and chemical reactions application.
1. anti-freeze & raw material in the production of polyester fibers.
