Why can EVA do glass spacers?

2022-09-16

There are two kinds of EVA gaskets for glass, one of which is EVA material.

It has good toughness, water resistance, corrosion resistance, machinability, moisture and shock resistance, and meets the requirements of individual production.

Many people may have the impression that EVA is a hard rubber plastic. Why can it be made into EVA gasket for protection?

In fact, the performance of EVA is closely related to the content of vinyl acetate (VA). When the VA content is increased, its resilience, flexibility, adhesion, transparency, solubility, stress crack resistance and impact resistance will be improved. When the VA content is reduced, the rigidity, abrasion resistance and electrical insulation properties of EVA are increased.

Generally speaking, when the VA content is in the range of 10%~20%, it is a plastic material, and when the VA content exceeds 30%, it is an elastic material.
