Ecoflex® Rubbers are platinum-catalyzed silicones that are versatile and easy to use. Cured material is certified by an independent laboratory to ISO 10993-10, Biological evaluation of medical devices, Part 10: Tests for irritation and skin sensitization. Ecoflex® Rubbers are mixed 1A:1B by weight or volume and cure at room temperature with negligible shrinkage. Rubber also cures with a dry surface. Low viscosity ensures easy mixing and de-airing, or you can choose to mix and dispense using our convenient dispensing cartridges.

Ecoflex® 00-35 FAST is certified by an independent laboratory to OECD TG 439. Liquid Ecoflex® 00-35 FAST will cure against the skin and can be used for life casting applications to make rubber molds that cure quickly and are good for casting wax, resins, etc.

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.
