• Long catalyst lifetime due to low deactivation rate
• Dedicated low by-product level

The main uses of MA include:

• Unsaturated polyester resin (UPR)
• 1,4 butanediol (BDO)
• Specialty acid, such as malic, fumaric polyaspartic acids
• Lubricating oil additive
• Polybutylene succinate (PBS), biodegradable aliphatic polyester
• Others, such as engineering plastics, fine chemicals, pharmaceuticals
