Solarex experience with ethylene vinyl acetate encapsulation

Solar Cells, 1991
Abstract Solarex began using ethylene vinyl acetate (EVA) as an encapsulant for photovoltaic modules during the Jet Propulsion Laboratory sponsored Block IV Program in 1979. Experience was gained in the processing and use of EVA during a number of Department of Energy sponsored projects through the early 1980s.

Photo-oxidation of ethylene-vinyl acetate copolymers

Polymer Photochemistry, 1983
Abstract Photo-oxidation of two ethylene-vinyl acetate copolymers (EVA) with vinyl acetate contents 45·0 and 65·0 wt% has been compared with the photo-oxidation of poly(vinyl acetate) and polyethylene samples under the same experimental conditions.

Solution properties of ethylene‐vinyl acetate copolymers

Journal of Polymer Science Part A-1: Polymer Chemistry, 1972
AbstractHigh‐pressure ethylene–vinyl acetate copolymers of four different chemical compositions(9%, 15%, 45%, and 70% VA) were characterized to determine molecular weight and distribution. The four samples were fractionated by solvent–nonsolvent precipitation methods.

Rheological characterization of ethylene vinyl acetate copolymers

Journal of Applied Polymer Science, 1999
A series of ethylene vinyl acetate (EVA) copolymers was studied by dynamic mechanical spectroscopy to understand the relative influence of composition, structure, and molecular weight distribution on their rheological behavior in the melt. The examination of their viscoelastic properties in a large temperature range showed that the glass transition ...

The Crosslinking of Ethylene-Vinyl Acetate with Organometallic Compounds

Journal of Macromolecular Science, Part A, 1990
Abstract Organometallic compounds such as aluminum trialkyl (AIR3) and lithium alkyl react nonradically with ethylene-vinyl acetate copolymers (EVA) to yield very high crosslinking rates. The mechanism is characterized by simultaneous reactions: addition, reduction, and enolization accompanied with ethene and ethane elimination.

The morphology of ethylene—vinyl acetate emulsion

Journal of Colloid and Interface Science, 1977
Abstract Direct observation through an electron microscope of the microstructure of an emulsion particle of ethylene—vinyl acetate was done by using a freeze-etching method. The spherical emulsion particle is composed of regular-shaped microspheroids ca. 500 A in diameter. The structure of the emulsion film was also observed with electron microscopy.

Ethylene Vinyl Acetate Copolymer/Multi-Walled Carbon Nanotube Nanocomposites

Journal of Nanoscience and Nanotechnology, 2010
In this study relatively large amount of ethylene-vinyl acetate copolymer (EVA) (130 g) was melt-mixed with multi walled carbon nanotube (MWCNT) and the effect of mixing time and rotor speed on electrical properties were investigated. Also, to investigate the relationship between the degree of dispersion of MWCNT and conductivity, the dispersion of ...

Ethylene—vinyl acetate copolymers for packaging applications

British Polymer Journal, 1970
AbstractEthylene‐vinyl acetate (E‐VA) copolymers consist of a range of materials beginning with polyethylene and possessing a gradation of properties with increasingly higher concentrations of vinyl acetate (V‐OAc). The major property differences between E‐VA copolymers and polyethylenes which incorporation of V‐OAc confers are discussed with reference
