Plasticizer - an overview | ScienceDirect Topics
10.1.3 Plasticizer Plasticizers are general colorless liquids which are relatively nonvolatile. Most of the plasticizers used for carpets are esters of phthalic acids (phthalates) with a wide variety of long chain alcohols. Plasticizers are classified according to function or structure.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt. Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry.
Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture.
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.
Plasticizers in Paint & Coatings: Uses, Types and Selection
DOP or DnOP is light-colored, low volatility & odorless liquid. It was the most commonly used all-purpose plasticizer, although mainly used for polyvinyl chloride (PVC) resins. It is insoluble in water & has a low viscosity of 56 mPa.s at 25°C. DOP features: Good stability to heat and ultraviolet light; Broad range of compatibility, and
- What is plasticizer?
- What is Plasticizer?
- Plasticizers are a class of chemicals widely used in plastic products to improve their flexibility, ductility, and processability. They increase the plasticity of the plastic and reduce its brittleness, making it easier to bend, stretch, and mold.
- Why is plasticization important?
- Plasticization is the process of making the final plastic product more flexible. By incorporating the right type and amount of plasticizer you can tweak your formulation. Hence, selecting the right plasticizer for a specific application is very critical to make the product softer. Plasticization can occur both internally and externally.
- How do Plasticizers improve plasticity?
- The molecules of plasticizers can insert themselves between polymer chains, increasing the distance between the chains and weakening intermolecular forces. This makes the polymer more flexible and easily bendable. It enhances the plasticity of plastics, making them easier to bend and deform.
- Why are plasticizers important in biopolymer-based films & coatings production?
- In biopolymer-based films and coatings production, plasticizers are also essential additives since they can improve flexibility and handling of films, maintain integrity and avoid pores and cracks in the polymeric matrix .
- What is a primary plasticizer & a secondary plasticizer?
- Plasticizers are used to convert PVC, a rigid plastic, into a soft, flexible, and elastic material. 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.
- What is the solvating strength of plasticizer?
- The solvating strength of plasticizer depends on its chemical structure as it relates to its physical properties. Application of Hansen solubility parameters (δ d = dispersion interactive forces, δ p = dipole interactive forces, and δ h = hydrogen bonding forces) is the most successful method of predicting interaction between plasticizers and PVC.
