Secondary Plasticizers | Galata chemicals
Drapex Secondary Plasticizers Epoxidized compounds for a wide range of applications Focusing our efforts on delivering greener and more sustainable solutions, the DRAPEX plasticizers are manufactured from renewable feedstock and effectively serve as both secondary plasticizers and co-stabilizers in nearly all PVC systems.
Effect of Modified Cardanol as Secondary Plasticizer on
act as an epoxy curing agent and as a plasticizer.2631 The use of cardanol as the primary or secondary plasticizer can enhance the exibility and thermal stability and decrease the volatility of PVC materials.3235 It has also been suggested that some renewable plasticizers have good leaching resistance, plasti-
Plasticizer - an overview | ScienceDirect Topics
A plasticizer that is compatible with PVC and exhibits low volatility, good permanence, and high efficiency is referred to as a primary plasticizer. A secondary plasticizer has the opposite characteristics of a primary plasticizer. The amount of plasticizer needed to obtain a certain hardness or elongation is a measure of its efficiency.
Triacetin as a Secondary PVC Plasticizer | SpringerLink
The use of biobased plasticizers with low toxicity and good compatibility with polyvinyl chloride (PVC) has become more attractive in the recent years in contrast with phthalate derivatives. In this study, a glycerol derivative plasticizer (triacetin—TAG) was tested as a secondary plasticizer for PVC. TAG was added to PVC formulations from 10 up to 20 phr. The increase of the plasticizer
Effect of Modified Cardanol as Secondary Plasticizer on
The substitution of DOP with MC enables PVC blends to have higher thermal stability, tensile strength, and leaching resistance. The tensile strength is increased from 17.7 MPa for DOP/PVC blend...
- What makes a polymer a good plasticizer?
- It is nowadays established that good plasticization implies secondary bonds, also known as intermolecular forces, with the polymer. The attraction between plasticizer molecules and the polymer must be as strong as the interactions between molecules in the single components to generate an efficient polymer-plasticizer interaction.
- What are the advantages of epoxy plasticizer?
- : Epoxy plasticizers offer good heat and light stability. : Used in food contact materials, coatings, and as secondary plasticizers. : Provide long-term stability and resistance to extraction and migration. : Used in automotive interiors, wire insulation, and flexible tubing.
- What is a primary plasticizer?
- A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- What are plasticizer characteristics?
- Plasticizer characteristics determine not only the compatibility but also the amount which can be added to the polymer while ensuring the thermodynamic stability of the mixture. Thermodynamic stability means the absence of plasticizer exudation at temperature changes, mechanical stresses, and pressure.
- Which plasticizer has a good plasticizing efficiency?
- Both plasticizers provided a satisfactory plasticizing efficiency, such as DEP, due to their low viscosity and ease of diffusion into CA, which enables a large processing window and increases the material's flexibility. CA with 30 wt% GTA displayed a slightly higher elastic modulus than CA with 30 wt% GDA (E = 2.1 GPa and 1.9 GPa, respectively).
- Do plasticizers increase polymers' flexibility at room temperature?
- Disentanglement of CA chains is favored at higher plasticizer content under extensional flow, yielding lower melt strength and higher melt extensibility . These observations confirm that plasticizers increase polymers' flexibility at room temperature and can be used as processing aids.
