What's the advantage of DPGDB compared with DOTP?
Dipropylene glycol dibenzoate (DPGDB) and dioctyl terephthalate (DOTP) are both commonly used as plasticizers in various applications, including the production of flexible PVC (polyvinyl chloride) products and water based adhesives&sealants&coatingse,ect.
Each of these plasticizers has its own set of advantages and disadvantages, and the choice between them often depends on the specific requirements of the application and the desired properties of the final product.
Here are some advantages of dipropylene glycol dibenzoate (DPGDB) compared to dioctyl terephthalate (DOTP):
1.Low Volatility: DPGDB has a lower volatility compared to DOTP, which means it is less likely to evaporate or migrate from the plastic material over time. This can be particularly beneficial in applications where the product is exposed to high temperatures or where long-term durability is required.
2.Improved Low-Temperature Flexibility: DPGDB can provide better low-temperature flexibility to PVC compounds, which is crucial for applications where the material needs to remain flexible in cold environments.
3.Good Compatibility: DPGDB is known for its good compatibility with PVC and other polymers, which can lead to a more uniform distribution of the plasticizer within the polymer matrix, resulting in improved physical properties of the final product.
4.Reduced Migration: Due to its chemical structure, DPGDB may exhibit reduced migration from the plastic material to other surfaces or into the environment, which can be important for maintaining the integrity of the product and for environmental considerations.
5.Improved UV Stability: Some formulations of DPGDB may offer better UV stability compared to DOTP, which can be beneficial for outdoor applications where the material is exposed to sunlight.
6.Lower Toxicity: DPGDB is generally considered to have a lower toxicity profile compared to some other plasticizers, which can be an important factor in applications where human contact is possible or where environmental impact is a concern.

It's important to note that the choice of plasticizer should be based on a comprehensive evaluation of the specific application requirements, including performance criteria, regulatory compliance, cost considerations, and environmental impact. Both DPGDB and DOTP have their own unique properties and may be more suitable for different applications.
