Effect of Plasticizer and Curing System on Freezing
Among the plasticizers, when DOP and DOA content was high, an appreciable decrease of T-g was found compared to TCP. Moreover, there was a remarkable decrease of T-g using DOA plasticizer, which
Effect of plasticizer and curing system on freezing
The role of plasticizers in freezing resistance is that it enters between the polymer molecules and reduces interaction among the molecules which in turn decrease the cohesive energy. The rubber materials with improved freezing resistance can be used for aero tires, air spring of express trains in railways, track mat of railway, automobiles, etc.

Effect of plasticizer and curing system on freezing
Among the plasticizers, when DOP and DOA content was high, an appreciable decrease of Tg was found compared to TCP. Moreover, there was a remarkable decrease of Tg using DOA plasticizer, which shows more effective on freezing resistance.

- Which plasticizer is best for freezing resistance of rubber?
- Also, oil-type plasticizers like paraffinic oil, P#2 and aromatic oil, A#2 have compatibility with rubber. However, it did not affect much of the main chain of rubber matrix chemically. So, it is well understood that DOA was the most proper plasticizer for improvement of freezing resistance of rubbers.
- Is DOA a good plasticizer for freezing resistance of rubbers?
- So, it is well understood that DOA was the most proper plasticizer for improvement of freezing resistance of rubbers. The changes in glass transition temperature, T gbecause of dif- ferent cross-linking systems was reported in Table III.
- How much migrated plasticizer can be cured at 180 °C?
- Samples cured at 180 °C show lower migration levels since, as we have stated before, the amount of free plasticizer is very small, so that the amount of migrated plasticizer varies in the 19–11% range for curing times of 8 and 16 min, respectively.
- Can epoxidized fatty acid ester be used as a natural-based plasticizer?
- The use of an epoxidized fatty acid ester (EFAE) as a natural-based plasticizer for plasticized PVC (P-PVC) has been evaluated in this work. The effect of the curing conditions has been studied by following several test techniques such as mechanical properties, thermal behavior, color changes, solvent migration and microstructure.
- Do plasticizers affect the viscoelastic properties of rubber?
- The content of plasticizers also affect the viscoelastic property of rubber (Oh et al., 2014). A special type of plasticizer can build tack or autohesion. ... ... The result of the physic-mechanical properties was evaluated to determine the most optimum cushion gum compound formula.
- What is the relationship between polar rubber and freezing resistance?
- Considering the relationship between molecular structure of rubber and freezing resistance, nonpolar rubbers like NR, BR, SBR, EPDM has low molecular cohesive energy and superior freezing resistance. On the other hand, polar rubbers like CR, NBR, and Acryl rubber have inferior freezing resistance. WWW.MATERIALSVIEWS.COM39795 (1 of 8)J. APPL. POLYM.
