Due to their high versatility in hot-melt formulations,
EVAs are leading polymers for hot-melt manufacturing. EVA based hot-melts
are able to fulfill various requirements in applications such as packaging,
bookbinding or label sticking.
They are highly flexible products, compatible with many other polymers
and additives, and are easy to process. Due to its chemical structure,
the EVA range:
are highly flexible
delivers high cohesive strength and compatibility
ensures excellent adhesion to a wide range of substrates
are highly resistant to rupture
Thanks to their high compatibility, they can be formulated
in combination with both natural or synthetic tackifiers,
a large range of PE waxes, modified waxes
or plasticizers and their intrinsic stability can be enhanced by the right
choice of antioxidant
or UV/Light
stabilizers;
