Plasticizers for PVC | POLYNT
Plasticizers trimellitates: they are characterized by an excellent flexibility at low temperatures and high resistance to higher temperatures; they are molecules primarily used in the production of electrical circuit components, wiring cables, car interiors and machinery components used in the medical and scientific field.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
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
Plasticizer Selection for Elastomers - Chemceed
Although majority of plasticizers are used in flexible PVC applications, a significant amount of plasticizers are used for elastomer applications. Plasticizers can be added to elastomers for various reasons: increasing softness or flexibility, lowering the glass transition temperature, reducing crystallization, increasing dispersion, or lowering the cost of the compound. Common plasticizers
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.
- How to choose a plasticizer for PVC?
- Using external plasticizers, it is very convenient to select from a variety of plasticizers depending on the desired properties and processability of PVC. Plasticizer is not only a processing aid but also an important component to determine the performance and application of PVC.
- 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 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 phthalate is used as a plasticizer for PVC?
- DTDP is the highest weight dialkyl phthalate to be used as a plasticizer. It was widely used as a high temperature plasticizer for PVC until trimellitates came into existence. It needs high processing temperatures for compounding with PVC. Cost: Phthalates are used as PVC plasticizers since the earliest days of flexible PVC.
- What are the different types of phthalate plasticizers?
- Among them, the most common are: Phthalate Esters – Produced by esterification of phthalic anhydride or phthalic acid. Obtained by the oxidation of orthoxylene or naphthalene. Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer
- 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.
