VINNAPAS® EAF 67 by Wacker is a vinyl acetate, ethylene and acrylate polymer dispersion. Exhibits excellent cohesion and adhesion even at elevated temperatures. Provides good heat resistance and frost resistance. It is an aqueous, plasticizer-free, white colored, APEO-free polymeric dispersion. VINNAPAS® EAF 67 is used as an adhesion promoter and is suitable as a raw material to manufacture floor covering adhesives, especially for carpets and PVC floor coverings. Other applications include pressure sensitive adhesives e. g. self-adhesive tapes, films, labels, sound and heat insulation mats.

COMPANY
Wacker Chemical Corporation supplies innovative products and technologies for the Adhesives and Sealants Industry so that customers can economically produce environmentally-compatible and high quality products that are tailored to their exact needs. With a wide range of applications, such as paper, packaging, flooring, wood, automotive, and construction, WACKER provides products for every solution.Wacker's leading solutions
The company's products enjoy strong market popularity because of its strong R&D fo-cus that has seen it releasing a dozen novelties at the last European Coatings ShowJune 2014
Munich (Germany)-based Wacker Chemie, targeting the Middle East's fast growing markets of construction, paints and coatings, adhesives, textiles, energy, plastics and elastomers, is offering a wide range of sealants and adhesives in which it is a world leader.
Vinnapas VAE dispersions from Wacker can be formulated into adhesives for various applications namely paper and packaging, wood and flooring. This technology is increasingly replacing other technologies due to its high performance, safety and versatility.
The company also offers Geniosil organofunctional silanes, innovative hybrid polymers for bonding and sealing, and a range of finished products for the construction industry.
"The Geniosil STP-E product line can be exploited to produce completely novel, fast-curing, one-component adhesives and sealants. The a-effect even permits the formulation of tin-free systems - representing a technological leap in user safety," a company spokesman says.
"Adhesives formulated with Geniosil STP-E possess outstanding mechanical properties. They do not require labeling, the formulations being free of plasticizers and solvents. Geniosil STP-E is used in numerous sophisticated adhesive formulations. In the Middle East, this technology is used for the construction industry especially for bonding, grouting or sealing.
"The products enjoy strong market popularity because Wacker solutions utilise German technology to cater to local needs."
Giving an insight into their special features, the spokesman said the market for flooring adhesives demands products which provide excellent bonding strength, dimensional stability and workability while at the same time they have to comply with environmental labels. "With Vinnapas VAE co- and terpolymers, Wacker offers both high-performance binders with an excellent property profile and the possibility to meet strict regulations. This makes them ideal to formulate adhesives for a wide variety of flexible floor coverings.
Success in the adhesives and sealants market often depends onchoosing the right binder. VINNAPAS® vinyl acetate-ethylene (VAE)technology offers outstanding benefits in terms of performance,safety and versatility.For more informationon VAE technology, visit:www.wacker.com/moveVinyl acetate-ethylene (VAE) dispersions are copolymers produced by the emulsion polymerization of hard, polar vinyl acetate monomer and soft, hydrophobic ethylene monomer.Ethylene gives permanent flexibility tothe VAE polymer. No external plasticizeris thus necessary in VAEs

 

 

EVA, yumuşaklığı ve esnekliğinden dolayı "kauçuk" gibi görünen malzemelerin üretimi için kullanılan bir elastomerdir. Vinil asetat içeriği elastikiyet derecesini belirler. Ayrıca, gerilim çatlamaları ve UV radyasyonuna karşı iyi bir şeffaflığa, parlaklığa ve dirence sahiptir. EVA, sirkeye benzer (asetik asit) hafif bir kokuya sahiptir ve birçok elektrikli uygulamada bazı polimerlerin yanı sıra kauçuk ürünlerle de rekabet eder.
Özellikler
Esnek (kauçuksu). Şeffaf. Düşük sıcaklıkta iyi esneklik (-70 ° C). İyi derecede kimyasal direnç. Yüksek sürtünme katsayısı. Düşük sızdırmazlık başlangıcı sıcaklıkları. Yüksek ısı eritmeli yapışma. Çok iyi darbe dayanımı.Ekstrüzyon işlemleri için mükemmel optik özellikler.
