Selecting Plasticizers for Adhesives and Sealants
For example, plasticizers can be used to provide softness and flexibility, but they are also used to improve melt processability, compounding efficiency, or to reduce the drying time of waterborne systems. In certain cases, they perform even additional functions such as flame retardance.
Plasticizer - an overview | ScienceDirect Topics
Plasticizer efficiency is used to describe the ability of a plasticizer to make the product softer and is reported as a ratio of the slope of the hardness versus plasticized concentration to the slope of that found for DOP. The relationship of hardness and plasticizer concentration expressed in phr (parts per hundred resin) is shown in Figure 3.

Efficiency Table 1 compares several plasticizers and coalescents and denotes their compatibility with solventborne and/or waterborne coatings. It indicates there is little difference in plasticizer efficiency in solvent-based coatings. The efficiencies of these plasticizers were evaluated by adding the plasticizer at five different
Fast Fusing, Fire Retardant Plasticize TECHNICAL DATA SHEET
This plasticizer is recommended for applications where there is a need to reduce the risk of fire. This versatile additive has FDA clearances making it an option for applications that involve indirect food contact. In PVC, Santicizer 141 acts as a high solvating plasticizer, offering performance, faster fusion and high plasticizing efficiency.
Mechanical and durability properties of soft PVC plasticized
The efficiency of the plasticizers, were significantly improved by increasing the yield of epoxidation. Also, mechanical properties performed after ageing showed the excellent stability of the properties of the cardanol derived plasticizer characterized by the higher yield of epoxidation.
- Which plasticizer has the best plasticizing efficiency?
- It's worth noting that PSCH has the best plasticizing efficiency attributed to the C–Cl bond on the side. According to the similar compatibility principle, except for hydrogen bonding, the existence of C–Cl bond in PSCH increases the compatibility of plasticizer and PVC.
- Why is plasticizer important?
- Plasticizer is not only a processing aid but also an important component to determine the performance and application of PVC. Therefore, plasticizers are the most important commercial application of PVC. However, plasticizers can leach out of flexible PVC, changing the performance of PVC with age and contaminating the environment.
- Does PSCH plasticizer reduce polarity of PVC molecules?
- The results show that the plasticizing efficiency of PSCH plasticizer is superior to that of other polyester plasticizers, up to 153%. The difference of solubility parameters DS between PSCH and PVC is the smallest, and the decrease of C–Cl bond energy in XPS also proves that PSCH can effectively reduce the polarity of PVC molecules.
- Which plasticizer is better – DOP or PVC?
- As it is shown above Table 2, the greatest improvement in plasticizing efficiency for PVC is observed with the addition of PSCH (142.6%), and compared with DOP, the plasticizing efficiency is increased by about 40%. Besides, the plasticizing effect of PSBH, PSPH and PSNH plasticizers is also slightly better than DOP.
- Can plasticizer improve the plasticity of polyvinyl chloride (PVC)?
- Plasticizer is an important assistant in the production process of polyvinyl chloride (PVC), which can effectively improve the plasticity of PVC. However, the durability and plasticizing effect of traditional phthalate plasticizers need to be further improved.
- Is PVC a good plasticizer?
- Thermal stability studies showed that PVC blends with HPGs were more stable (exhibiting higher onset temperature values on TGA curves) than samples with DEHP. A great number of ether and ester groups in a plasticizer molecule provide donor-acceptor interactions with PVC, resulting in an excellent migration resistance.
