Frequently Asked Questions

The core advantage of DOA is its strong cold resistance, helping PVC products remain soft, flexible, and resistant to hardening or cracking at low temperatures while improving hand feel and flexibility for cold-environment applications.

DOA is mainly used in flexible PVC formulations requiring low-temperature flexibility, such as frozen packaging films, cold-resistant cables, hoses, synthetic leather, automotive interiors, and winter outdoor flexible materials. It effectively reduces the risk of low-temperature embrittlement while improving cold resistance and processing stability.

DOA provides excellent low-temperature flexibility, while DOTP offers stronger stability and migration resistance. When blended, they improve cold resistance, softness, and long-term performance stability, making them suitable for PVC formulations requiring both low-temperature performance and balanced overall properties.
