1 trial unit - 2 lbs total silicone Smoth-On Ecoflex Supersoft Silicone Ecoflex Rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex Rubbers are mixed 1A:1B by weight or volume and cure at room temperature with negligible shrinkage. Rubber also cures without a "tacky" surface. Low viscosity ensures easy mixing and de-airing. Ecoflex 00-50 - Shore 00-50 hardness (below the Shore A scale) Cured rubber is very soft, very strong and very "stretchy", stretching many times its original size without tearing and will rebound to its original form without distortion. Ecoflex Rubbers are water white translucent and can be color pigmented with Silc-Pig pigments for creating a variety of color effects.
