DOP Plasticizer Improves PVC Profile Processing Stability and Surface Quality

Based on the production requirements for customers’ construction profiles, Henan GO Biotech Co., Ltd. provides DOP plasticizer formulation support, optimizing PVC processing flowability, continuous extrusion stability, and profile surface finish.

Project Background and Challenges

The customer primarily manufactures PVC profiles for architectural decoration and door and window applications. As market requirements for profile appearance consistency, processing continuity, and delivery efficiency increased, the customer sought to improve the processing performance of its PVC formulation while maintaining its existing equipment and process conditions.

✓Extrusion Stability:Reduce the impact of plasticization, flow, and pressure fluctuations on continuous production.

✓Surface Forming Quality:Reduce appearance risks such as rough surfaces, flow marks, and localized inconsistencies.

✓Processing Flowability:Improve material adaptability during extrusion and die forming.

PVC Profile Production and DOP Plasticizer Processing Application in Morocco

Solution: Enhancing PVC Processing Adaptability with DOP

For standard flexible and modified PVC processing applications, Henan GO Biotech Co., Ltd. recommended DOP (di(2-ethylhexyl) phthalate) as a general-purpose PVC plasticizer and provided formulation optimization support based on the customer's existing production conditions.
