Adaptive3D™ Elastic ToughRubber™ 70 (ETR70)

ETEC DuraChain™ Photopolymers

Elastic ToughRubber™ 70

400% Elongation-at-Break

Elastic ToughRubber™ 70 is flexible and has an excellent elongation to break performance snapping back to shape each time. It is the perfect elastomer for shoe midsoles and heel cups, seals, door boots, bellows, foam-like lattice structures and impact parts.

Elastic ToughRubber™ 70 is part of the Elastic ToughRubber family of elastomers with a one-part one-pot polymer system. This means there is no mixing of two materials in the proper ratios, which can lead to poor quality if not done correctly. ETR is also pot stable so there is no wasted resin at the end of the print.

Key Features:

  • Higher Performance
  • One-part, one-pot polymer system that simplifies storage and processing for a cleaner safer production environment
  • Simplicity and ease of use
  • Faster and more affordable part production time
  • High tear strength, high resilience (elasticity), high strain, high tensile strength
  • Cost-efficient as you can simply use the leftover resin to print your next part!
