EVA

    In order to make refrigerator ducts, gas pipes, civil construction plates, containers and daily necessities, etc., it can also make packaging films, gaskets, medical devices, and can also be used as hot melt adhesives, cable insulation layers, etc. Now in the solar cell industry, it is used in the bonding of the solar cell in the crystalline silicon cell with the surface photovoltaic glass and the battery back sheet.

    content and function

    The function of EVA is closely related to the content of vinyl acetate (VA). When the content of VA increases, its resilience, flexibility, adhesion, transparency, solubility, stress crack resistance and impact function will all be Increase; when the content of VA decreases, the rigidity, wear resistance and electrical insulation of EVA will increase. Generally speaking, when the VA content is in the range of 10% to 20%, it is a plastic material, and when the VA content exceeds 30%, it is an elastic material.

    It is a solid at room temperature, and it is heated and melted to a certain extent to become a movable liquid with a certain viscosity.

    EVA rubber and plastic products are new environmentally friendly plastic foam materials, which have good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and are non-toxic and non-absorbent.
