Product Overview: Engineered specifically for the demanding requirements of tire manufacturing and prototyping, our RTV-2 Liquid Silicone Rubber offers exceptional fluidity and tear strength. Whether you are reproducing intricate tire treads, sidewall lettering, or complex undercuts, this silicone ensures perfect detail reproduction with zero distortion.
Key Features:
-
Superior Flowability: Low viscosity ensures the silicone flows easily into deep tread grooves and complex patterns without trapping air bubbles.
-
High Tear Strength: Specially formulated to withstand the stress of demolding complex geometries. It prevents tearing even when pulling the mold from deep undercuts.
-
Low Shrinkage: With linear shrinkage of less than 0.3%, it guarantees the dimensional accuracy and roundness of the final tire product.
-
Optimal Hardness: Available in Shore A 30-40, providing enough rigidity to maintain the tire’s shape during casting while remaining flexible enough for easy demolding.
-
Chemical Resistance: Excellent resistance to polyurethane (PU) resins, epoxy, and gypsum, ensuring a long mold library life.
Applications:
-
Automotive tire prototyping.
-
RC (Remote Control) car tires.
-
Industrial rubber rollers and wheels.
-
Gypsum or concrete tire-shaped decorations.
