The Effect of Plasticizers on Vibration Damping in Polyvinyl
The Effect of Plasticizers on Vibration Damping in Polyvinyl Chloride (PVC) Formulations 2015-01-2204 The ability of various plasticizers to impact the vibration damping properties of polyvinyl chloride (PVC) plastisols was investigated. A material must have good viscoelastic properties in order for it to be an effective vibration damper.
The effect of additives on vibration damping in Polyvinyl
The effect of additives on vibration damping in Polyvinyl Chloride and Acrylic formulations This is a Past Webinar Materials must have the right balance of elastic and viscous properties to provide effective vibration damping. Additives can be used in polymeric systems to enhance vibration damping.
Effects of Polyol-Based Plasticizer Types and Concentration
The plasticizers are non-volatile small molecules that increase the flexibility, distensibility and processability of the polymer matrix material. They perform this function by increasing polymer chain mobility and decreasing intermolecular interactions [ 33, 34 ].
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.
- 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.
- How do plasticizers affect the viscoelastic properties of PVC gels?
- In PVC gel systems, the viscoelastic properties exhibit a pronounced dependence on frequency . Microscopically, the introduction of plasticizers has the effect of weakening the interactions between the PVC molecular chains and reducing the degree of polymerization of the internal network.
- What is the relationship between plasticizer and PVC?
- The higher the binding energy is, the stronger the interaction between plasticizer and PVC is, and the more difficult it is for plasticizer to migrate out of the PVC system. In plasticized PVC system, its expression is as follows:
- Why do Plasticized PVC films elongate at break?
- Compared to pure PVC, all plasticized PVC films had a larger elongation at break. This was attributed to the lubricating effect produced by the addition of plasticizers , thereby reducing the slip resistance between the PVC chains.
- Are PVC plasticizers harmful?
- Currently, the widely used PVC plasticizers are phthalates, and it can even make up 40% of raw material . However, these small molecule plasticizers easily migrate into the environment and cause unignorable harmful effects on the human body , .
- Is macromolecular PVC plasticizer better than DOP?
- The macromolecular PVC plasticizer showed good plasticization effect. Although its plasticization efficiency was lower than DOP, the macromolecular plasticizer endowed PVC good thermal stability, high migration resistance.
