Application scenario related issues
DOTP may migrate in some rubber products because its compatibility with certain rubbers, such as nitrile rubber, is lower than that of DOP. Excessive use can cause surface blooming, migration, and reduced dimensional stability. These issues can usually be improved by controlling the dosage, optimizing the formulation, or combining DOTP with other plasticizers.
Why Does DOTP Sometimes Migrate in Rubber Products?
DOTP migration in rubber products is mainly related to its compatibility with the rubber material and the dosage used in the formulation. Compared with DOP, DOTP may have lower compatibility with certain rubbers, such as nitrile rubber.
When DOTP is added in an excessive amount, it may result in:
- Surface blooming or frosting
- Plasticizer migration or exudation
- Reduced dimensional stability
These issues can usually be improved through formulation adjustment. Common approaches include:
- Controlling the amount of DOTP used
- Optimizing the rubber formulation
- Blending DOTP with other plasticizers to improve compatibility
Henan GO Biotech Co., Ltd. focuses on plasticizer development and production, supporting B2B customers in evaluating dosage, compatibility, and formulation requirements for rubber applications.
