The lowdown on EVA and EVA foam safety - Hello Natural Living
EVA is considered to be a safe alternative to PVC, as it doesn’t require plasticizers like phthlates, and it’s BPA free. However, a few years ago it was found that EVA foam contained formamide. Formamide is used to make the foam soft, but it’s considered to be carcinogenic and a developmental toxin. Formamide can be absorbed through the
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.
What Plasticizers Do & How They Affect Properties | Osborne
Posted May 17, 2025. Plasticizers are non-volatile chemical solvents used throughout the plastics industry to increase such properties as flexibility, pliability, durability, longevity, biodegradability, and extensibility in polymers. When added to a plastic or elastomer, plasticizers affect the properties of the material without fundamentally
Types of Insulation | Department of Energy
Icynene foam can be either sprayed or injected, which makes it the most versatile. It also has good resistance to both air and water intrusion. Tripolymer foam—a water-soluble foam—is injected into wall cavities. It has excellent resistance to fire and air intrusion. Installation

- How to choose a plasticizer?
- The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use. This may include low volatility, high permanence, low temperature flexibility, flame retardancy, high thermal stability and saponification resistance.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- 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.
- Are phosphates a good plasticizer for PVC?
- Phosphates are primary plasticizers for PVC. They can be utilized as sole plasticizers or in a cost-optimized blend. Triaryl phosphates show excellent flame retardancy with low volatility. However, they have poorer low-temperature flexibility.
- What is the best phthalate-free plasticizer?
- As there is an increasing demand for phthalate-free plasticizers, Benzoate plasticizers offer the best alternative by providing similar benefits in their applications. NK-131 is a specialty plasticizer that is used as an alternative for Diisobutyl Phthalate (DIBP), Dibutyl Phthalate (DBP) and Benzyl Butyl Phthalate (BBP).
- Are polymeric plasticizers adipates?
- 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. Many have poor low-temperature properties and may be sensitive to moisture. Check out the table below for the benefits of polymeric plasticizers.
