Preparation and properties of ethylene vinyl acetate copolymer silica nanocomposites in presence of eva g acrylic acid april 2015 journal of nanoscience and nanotechnology 15 4 2777 2784. Eva properties vary depending on the comonomers contents. The thermoelastic properties of the ethylene vinyl acetate copolymers eva ethylene content 67 79 weight as well as of the mixtures of eva ethylene content 55 weight with ethylene propylene copolymer epc polystyrene ps and polyvinyl chloride pvc were studied.
Eva is an elastomeric polymer that produces materials which are rubber like in softness and flexibility. Ethylene vinyl acetate copolymer eva and monmorillonite mmt nanocomposites have been investigated as a function of vinyl acetate content and havior of polyethylene co vinyl acetate eva in high tem perature such as. It shows good chemical resistance. Eva shows good barrier and stretch properties.
Ethylene vinyl acetate or eva is a copolymer of ethylene and vinyl acetate with a structure as shown below. The material has good clarity and gloss low temperature toughness stress crack resistance hot melt adhesive waterproof properties and resistance to uv radiation. Ethylene vinyl acetate is a flexible and transparent thermoplastic. 1 price 2 plastics polymers ethylene vinyl acetate 1 2 341 ethylene vinyl acetate a k a.
Ethylene vinyl acetate eva is a random copolymer of ethylene and varying amounts of vinyl acetate va. It is an extremely elastic and tough thermoplastic of excellent clarity and gloss and with little odor. In all cases the dependence of equilibrium. Ethylene vinyl acetate offers good low temperature flexibility.
Eva has many attractive properties including low cost excellent adhesion to manypolar and nonporous substrates good flex crack and puncture resistance as well as good hot tack and heat sealing. Explore ethylene vinyl acetate properties in the table below for an easy selection. Eva is used in several applications thanks to the varied properties it possesses. The eva copolymer which is based on a high proportion of va greater than 60 is referred to as ethylene vinyl acetate rubber.
As the va content increases crystallinity decreases until at 50 the eva is totally amorphous.
