Ethylene-vinyl acetate
EVA is an elastomeric polymer that produces materials which are "rubber-like" in softness and flexibility. The material has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation.
New Thermoplastic Damping Polymeric Materials Based on
glass temperature of EVA. The percentage ratio of EVA/plasticizer system is stated, and the type of plasticizer at which the maximum of mechanical losses takes over greater values is accordingly detected. It is revealed, that to work out DPM on EVA basis, which are effective in wide temperature range it is
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.
EVA Resins (Ethylene Vinyl Acetate) | Nexeo Plastics
Ethylene Vinyl Acetate, or EVA resin is a clear, hygroscopic, amorphous elastomeric material that can be processed through both thermoplastic and rubber processing techniques, including extrusion, blow molding, rotational molding and injection. With properties of both rubber and plastic products, EVA provides a useful combination of elasticity
Plasticized Ethylene - Vinyl Acetate Binders for Insensitive
Plasticizers have been incorporated into RDX ethylene-vinyl acetate EVA compositions prepared by the solvent slurry coating technique. The effect of plasticizers on impact sensitiveness, shock sensitivity, cookoff behavior and integrity of pressed pellets has been examined for compositions with EVA binders of varying vinyl acetate content.
- Why are plasticizers used in polyvinyl chloride?
- Plasticizers increase the flow and thermoplasticity of a polymer. This is done by decreasing the viscosity of the polymer melt, Tg, Tm, and elastic modulus of the finished product. During this process, the fundamental chemical character of the plasticized material remains unaltered. Plasticizers are most often used in Polyvinyl chloride.
- 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 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 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.
- 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.
- What are bio-based plasticizers?
- As the name says, biobased plasticizers are majorly based on: Few more plasticizers are based on renewably sourced isosorbides and alkanoic acids. Isosorbide diesters are a non-toxic alternative to phthalates. They offer promising properties to PVC. Being naturally/renewable sourced, bio-based plasticizers are sometimes easily approved for:
