Making one is easy. Making twenty is not.
VytaFlex 60 is a production-grade polyurethane mold rubber designed for creators who need more than a single successful prototype.

Used for resin casting, sculpture reproduction, prop fabrication, jewelry masters, prototype duplication, and small-batch production, VytaFlex allows makers to turn a finished design into a repeatable process.

Where silicone is often chosen for flexibility, polyurethane is frequently chosen for durability. Its combination of tear strength, abrasion resistance, and dimensional stability makes it a common choice for molds expected to survive repeated casting cycles while preserving fine detail.

Mix Ratio: 1A : 1B by Volume or Weight
