Elastomeric Materials
Elastomers are polymer materials with elasticity, meaning they can be stretched and return to their original shape.

Post-Processing
Green State Handling Elastomeric parts are much more fragile in their green state than their fully cured final part state. Do not apply too much force to parts during processing.
INCORRECT Green State Handling
Excessive squeezing of parts in the green state are likely to both deform the parts and alter material properties.
CORRECT Green State Handling
Minor handling is both acceptable and inevitable in processing, but use a delicate touch to maintain part integrity as shown here.
After secondary curing (baking), parts can be squeezed without issue.
Final Part State (After Baking)
Left: permanently deformed due to squeezing in the green state
- Parts may visibly, permanently deform during the thermal cure.
- Parts may micro fracture, invisible to the naked eye, but affecting of material properties.
Right: no deformation due to proper handling
