XS-T90 is a resilient elastomeric resin tuned for rebound: Shore 80A firmness, 10 MPa tensile strength, and 160% elongation at break, so parts stretch far and snap back rather than deforming permanently. It’s built for micro seals under repeated compression, strain reliefs, flexible couplings, living hinges, and energy-return features in devices that cycle constantly.
Where XS-T60 provides softness, XS-T90 provides spring — the firmer durometer holds sealing force and returns energy, while the high elongation absorbs overload without tearing. Its 600 cps viscosity supports clean printing of thin flexures and fine sealing lips, and stable dielectric behavior (3.0 @ 5 GHz) keeps it compatible with electronics-adjacent applications.
The transparent formulation offers optical clarity for flow visualization, internal-feature inspection, and light-transmission applications.
XS-T90 is engineered spring: elastomeric micro parts that flex, seal, and rebound cycle after cycle.
