Ateva G Medical Grade Ateva G ethylene vinyl acetate (EVA) grades are used in medical plastic applications such as tubing, devices, medical bags, and
Innovative Uses of Ethylene Vinyl Acetate Polymers
In the 1970’s and 1980’s alternatives to PVC plastic IV bags were sought because the phthalate plasticizer, commonly used in PVC, was leaching into nutrition fluids including the lipid components. Case Study 1 – EVA Innovation EVA was found to be an excellent solution for TPN bags. EVA offered the ability to have high flexibility
EVA Flexible Copolymer | Ethylene Vinyl Acetate (EVA) Plastic
Flexible EVA (ethylene vinyl acetate) is the copolymer of ethylene and vinyl acetate. It’s an extremely elastic material that can be processed like other thermoplastics. The material has low-temperature toughness, stress-crack and UV radiation resistance. In the Orthotic and Prosthetic market, fabricators know this material as either: OP-TEK
Plasticizers: Types, Uses, Classification, Selection & Regulation
Bio-based Plasticizers – They are based on epoxidized soybean oil (ESBO), epoxidized linseed oil (ELO), castor oil, palm oil, other vegetable oils, starches, sugars etc. Others – Includes Phosphates, Chlorinated Paraffins, Alkyl Sulfonic Acid Esters and more When added to polymer, these plasticizers provide several benefits as listed below.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- What is ultrathene ethylene vinyl acetate (EVA)?
- Ultrathene ethylene vinyl acetate (EVA) copolymers combine many of the advantages of low-density polyethylene (LDPE), such as clarity and toughness, with outstanding flexibility, low-temperature performance and lower heat seal initiation temperatures.

- 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 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.
- What are plasticizers & how do they work?
- Plasticizers are non-volatile organic substances (mainly liquids) added into a plastic or elastomer. They are also usually cheaper than other additives. They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer.
- What is evaflex TM?
- EVAFLEX ™ exhibits flexibility and elasticity characteristics. In addition: It is flexible and non-toxic without needing a plasticizer. It boasts excellent low temperature properties. It is highly weather resistant and does not exhibit ozone aging.
