eva properties.
It is a solid at room temperature, heated and melted to a certain degree into a liquid that can flow and has a certain viscosity.
EVA rubber products is a new environmentally friendly plastic foam material, with good cushioning, shock resistance, heat insulation, moisture, chemical corrosion resistance and other advantages, and non-toxic, non-absorbent.
eva use.
For the production of refrigerator ducts, gas pipes, civil construction panels, containers and daily necessities, etc., can also be used for packaging film, gaskets, medical equipment, can also be used as hot melt adhesives, cable insulation layer. Currently used in the solar cell industry for the bonding of cells to surface photovoltaic glass and cell backsheets in crystalline silicon cells.
