Ultra-High Elasticity

With an ultra-high 391% elongation at break, EL400 combines rubber-like elasticity and hardness, offering excellent flexibility and stability to realize your innovative designs.

Excellent Resilience and Rebound Performance

The EL400’s 50–55% Bayshore rebound rate* makes returning to its original shape after deformation seamless. Ideal for durable prototypes for long-term testing and repeated use.

Applications

Perfect for products with high-durability needs, such as bicycle seats and shoe cushions, it maintains optimum performance under repeated bending and tearing conditions, ensuring long-term use and reliability.

Post-Processing

Cleaning and Drying

Wash in 95% ethanol using Phrozen Washing Station until its thoroughly cleaned (don’t soak for a prolonged period to avoid surface damage), then place in a cool, ventilated area away from sunlight until it dries, or use the drying function in the Phrozen Curing Station.

Post-Curing

Soak the models in glycerin and post-cure for about 60 minutes. Once completed, remove from glycerin immediately and clean up the models with water. Leave models in a cool, well-ventilated place for at least 60 minutes without exposure to light to dry.

Final Cleaning

Rinse the model with clean water until it’s thoroughly cleaned and dry in a cool, ventilated area away from sunlight for 60 minutes until the model dries completely. If required, an additional thermal post-cure at 80°C for 2 hours can be performed to enhance the mechanical properties of the models.
