Plasticizers from Evonik - Evonik Industries
Plasticizers from Evonik offer manufacturers of flexible PVC and their products flexibility, safety and above-average technical performance with a consistently high level of quality. Plasticizers act like a molecular lubricant: The molecules sandwich themselves between the polymer chains of PVC. This makes the originally tightly-packed, rigid

Comparison of High Solvating Plasticizers in 1K Polyurethane
All Valtris Plasticizers as well as the alkyl sulfonic ester show similar tack free times. The Benzoate plasticizer has a delayed tack time response. Cure Through - Material was applied in in. thickness. Samples were cut daily to determine how long it takes the product to cure all the way through. Data was determined in days.

Payflex Series Plasticizers - High Quality Plasticizers
Plasticizers are used to enhance the overall flexibility of the product while reducing friction and making it easy for the polymer to bend and mould. Below are some of the many properties of high-quality plasticizers that we manufacture at Payal Group: They are designed to have a high boiling point. It offers stretchability, high efficiency
- Which monomeric plasticizer is most effective?
- Of the monomeric plasticizers tested, DB(3E)A and DADEG appear most effective. It should be noted these are the highest molecular weight of the monomeric esters tested. The low viscosity (and molecular weight) of polymeric A1100 appears to offer low-temperature flexibility and permanence suitable to acrylic elastomers.
- How to choose a general-purpose plasticizer for PVC?
- While selecting a general-purpose plasticizer for PVC, the main attributes to be checked are: Among them, regulation is an important decision factor while selecting plasticizers. In recent years, there has been a lot of discussion on phthalate plasticizers. But in fact, not all phthalates are prohibited.
- How are plasticizers classified?
- Plasticizers are classified based on their chemical composition. It is important to understand the influence of structural elements on the properties of plasticizers and their effect on base polymers. For example, the presence of elements like alcohols in a homologous series of phthalates, and adipates.
- What are natural product type plasticizers?
- Vegetable oil derivatives are the most widely used natural product type plasticizers. Products consisting of triglyceride esters of unsaturated fatty acids (e.g., soybean oil, linseed oil) in which the double bonds in the fatty acid residues have typically been epoxidized have been commercial products for decades.
- What is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- Are plasticizers effective in reducing low-temperature elastomer test values?
- Plasticizers, when added to acrylic elastomer compounds, can reduce the low-temperature test values obtained compared to unplasticized compounds. Of the monomeric plasticizers tested, DB(3E)A and DADEG appear most effective. It should be noted these are the highest molecular weight of the monomeric esters tested.
