Effect of Modified Cardanol as Secondary Plasticizer on Thermal and
improve the compatibility of the plasticizer with PVC.5,25 The biobased cardanol oil isolated from cashew nut shell liquid can 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
Jayflex plasticizers for advantaged performance
indicates that the plasticizer is tolerant of the use of secondary plasticizers. Jayflex DINP and DIDP plasticizers help to better achieve the key stages of flexible PVC processing, such as dryblending, full fusion and development of optimum mechanical properties. Good plastisol pre-gelation and fusion When processing plastisols, the gelling energy
Selecting Plasticizers for Adhesives and Sealants
Plasticizers are one of the commonly used additives in adhesives and sealants formulations. They improve the performance of adhesives by creating much-needed flexibility, optimizing viscosity, toughness, set time functionality, impact resistance, and even adhesion.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Secondary plasticizers may have limited compatibility with the polymer and/or high volatility. They may or may not contain functional groups which allow them to solvate the polymer at processing temperatures. Secondary plasticizers are variously used for: Cost reduction Viscosity reduction Solvency enhancement Surface lubricity augmentation, and
A Strategy for Nonmigrating Highly Plasticized PVC
It is speculated that covalently combining phthalates and CP with appropriate chlorination degree and structure can yield a large number of plasticizers with high plasticizing efficiency and...
- 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.
- Which plasticizer has the best plasticizing efficiency?
- It's worth noting that PSCH has the best plasticizing efficiency attributed to the C–Cl bond on the side. According to the similar compatibility principle, except for hydrogen bonding, the existence of C–Cl bond in PSCH increases the compatibility of plasticizer and PVC.
- 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 types of plasticizers are used in hydrophilic polymers?
- In addition to water, the most commonly used plasticizers are polyols, mono-, di- and oligosaccharides. Polyols have been found to be particularly effective for use in plasticized hydrophilic polymers .
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- Which plasticizer is most commonly used?
- : Phthalates are the most commonly used plasticizers due to their high efficiency and low cost. : Widely used in flexible PVC applications like cables, flooring, and medical devices. Concerns: Environmental and health concerns have led to restrictions and reduced use, especially in sensitive applications.
