Adaptive3D™ Elastic ToughRubber™ 90 (ETR90)

ETEC DuraChain™ Photopolymers

Elastic ToughRubber™ 90

An elastomeric 3D printing material with high tear strength, resiliency and performance

Adaptive3D Elastic ToughRubber™ 90 (ETR 90) is an elastomeric material with a tough, rubber-like performance, allowing for the 3D printing of parts previously made from technical foams, rubbers, or polyurethanes.

Tough, flexible, usable, and functional parts

E-RE90 is one of the toughest elastomers on the market with high performance that is ideal for a multitude of end parts, products, and functional prototypes such as midsoles, heel cups, seals, and door boots, foam-like lattice structuring, or tough enclosures. It is also recommended for vibration isolation parts due to its extraordinary damping properties.

Key Features and Benefits

  • Exceptional design geometries
  • Modulus and performance comparable to the foamed thermoplastic polyurethane (TPU)
  • Stable performance in all weather due to its glass transition temperature that ranges from -60°C to +63°C
  • Durable and long-lasting for end-use
