Technical Datasheet E180F
Product Description:
EVA E180F resin is an EVA resin for crosslinked foam applications including mid-sole and in-sole of athletic shoes. This grade is designed to be processed in conventional kneading and rolling equipment for mixing and dispersing crosslinking agent and foaming agent. This grade offers good processability during compounding with various additives. Foamed products made of this grade provide excellent spilt tear resistance, superb tensile and elongation properties, and good compression set characteristics.
Applications:
Athletic shoe mid-soles and in-soles, Sandals, Cushion padding.
