Advanced Medical-Grade Compounds - PVC plasticizers - Tekni-Plex
The three prominent PVC plasticizers are DEHP, DINP and DIDP and they are all dialkyl ortho-phthalates. Over the last 60 years, the most common plasticizer used to soften PVC compounds used for medical devices has been DEHP Di-2 ethyl hexyl phthalate.
PVC Plasticizers and Stabilizers Following Safer Sustainable
PVC is hard and brittle and is only moldable with the addition of a plasticizer and stabilizer. Stabilizers make the processing of PVC possible and safe in the finished product from environmental effects such as heat, ultraviolet light and oxygen.
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
- What is low-molecular-weight plasticizer?
- Low-molecular-weight plasticizer is one of the major additives used in PVC compounding. The addition of plasticizers to a PVC formulation decreases many mechanical properties of the PVC product (hardness, tensile strength, modulus, etc.); however, low-temperature flexibility, elongation, and the ease of processing are all improved.
- 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.
- Why do we need plasticizers in polyvinyl chloride (PVC)?
- Plasticizers play a crucial role in the overall performance and usability of polyvinyl chloride (PVC). Their addition can significantly alter the mechanical properties of PVC, thereby expanding its application range.
- What makes a good plasticizer?
- A good plasticizer must blend uniformly with the PVC matrix, ensuring that it does not phase-separate or lead to inconsistency in the material properties. An effective means to evaluate compatibility is through the analysis of: Solubility: The plasticizer should dissolve in PVC without forming precipitates.
- What are the different types of plasticizers?
- There are two main groups of plasticizers: primary—the main plasticizer in a PVC blend, added in large quantities and highly compatible with PVC; and secondary—having limited compatibility with PVC, easily migrating, especially when used in excess and usually added to the blend to improve its properties or to reduce its costs . Figure 1.
- 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.
