Eects of molecular design parameters on plasticizer performance
the material’s Young’s modulus, and migration rate in the PVC matrix. The wide variety of plasticizer types covered in the study allows us to investigate the eects of seven molecular design parameters. Experimental ˙ndings about the eects of plasticizer molecular design are also compiled from various literature sources and reviewed.
A Strategy for Nonmigrating Highly Plasticized PVC
Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as
Current Status of Plasticizer Research | SpringerLink
Plasticizers are widely applied in food wraps and packaging, toys, PVC construction materials, automotive parts, rubber tires, electrical and medical devices, PVC cables, water pipes, plastic plates, soft PVC synthetic leather, etc. Plasticizers are the type of plastics processing additives that have the highest production capacity and consumption, ~60% of the overall additive production.
Eastman Product Finder | Product Catalog | Specialty Materials
Eastman Cellulose Acetate CA-398-30 is a high-viscosity, high molecular weight cellulose acetate supplied as fine, dry, free-flowing powder. Its relatively uniform particle size permits good plasticizer distribution during blending and it offers good physical properties for molded and extruded articles.
ABSORPTION CRITERIA FOR PLASTICIZERS IN S-PVC DURING MIXING - LinkedIn
An effective plasticizer molecule for PVC has two types of structural components – 1. Polar component, and 2. Non polar component. The polar component of the molecule must be able to bind...
- What is nonmigrating highly plasticized PVC?
- Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
- What happens when plasticizers are introduced into PVC gel?
- The introduction of plasticizers into PVC results in a transition from rigid PVC (solid) to soft PVC gel (colloid). In pure PVC gel, the PVC molecular chains form the internal network skeleton, restrict the migration of plasticizers, and provide a stable cross-linked structure .
- 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.
- Which plasticizer molecule provides a beneficial interaction with the PVC chain?
- There exist numerous structures of plasticizer molecules that provide beneficial interactions with the PVC chain, like ester groups, epoxy groups, aromatic rings, hydroxyl groups, etc.
- Why is PVC a good material?
- Because of the strong polar effect among PVC chains, pure PVC exhibits rigidity, brittleness and a high melt viscosity, resulting in a relatively high processing temperature and a high screw torque. PVC compounded with plasticizers is often used for applications that require flexibility.
- 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.
