Manufacturers of seals and injection-molded products often face challenges: difficult demolding, burrs on finished products, time- and energy-consuming secondary vulcanization, seals that tear easily over time, declining sealing performance, and concerns about materials not meeting industry standards. The IOTA LSR 3620 series secondary-vulcanization-free liquid silicone rubber effortlessly resolves these issues—offering fast demolding, excellent molding, superior mechanical properties, and labor and cost savings, making it the "efficiency expert" in sealing and injection applications.

This silicone is fully optimized for production adaptability. Its 1:1 two-component mixing ratio is as simple as mixing adhesive 1:1, lowering the operational threshold and eliminating the need for workers to repeatedly verify proportions. With moderate viscosity—like smooth silicone ointment—it flows easily into molds, precisely filling even the finest details for seamless injection molding. Demolding is a standout feature: cured products release effortlessly from molds, as easily as removing glass from a suction cup, with no mold sticking. This eliminates the need for additional deburring, streamlining the process. Curing is exceptionally fast—90 seconds at 130°C or 45 seconds at 150°C—eliminating long waits, doubling production efficiency, and saving significant energy by skipping secondary vulcanization. Post-curing, its mechanical properties excel: tear strength is as robust as durable rubber bands, with quick rebound after stretching. Available in hardness grades from 25 to 70 Shore A, it can produce soft waterproof seals or rigid small injection-molded components.

In sealing and injection applications, its performance is outstanding:

• Household appliance seals (e.g., refrigerator and washing machine door gaskets) are airtight, aging-resistant, and effectively moisture-proof and insulating.

• Pipeline seals are corrosion-resistant and flexible, maintaining leak-free and tear-resistant performance over long-term use.

• Daily-use silicone injection parts (e.g., keyboard silicone keys, earbud tips) feature smooth surfaces, comfortable texture, and responsive press-and-rebound.

• Medical device seals (e.g., infusion sets, ventilator components) comply with ROHS standards, withstand sterilization, and are non-irritating.

• Automotive small-sized seals resist high temperatures and aging, adapting to complex in-vehicle environments.

Using it is particularly hassle-free—just keep a few key details in mind:

• Only mix A and B components from the same batch to avoid performance issues from cross-batch combinations.

• Thoroughly stir materials before transfer to ensure flowability and uniformity for perfect molding.

• As a platinum-catalyzed product, avoid substances that could "poison" the catalyst. Small-scale testing before production is recommended.

• Store in a cool, dry place below 23°C—unopened, its shelf life is 12 months. Beyond this period, relevant performance tests can confirm continued usability.

Whether for automated injection production lines or small-scale manual manufacturing, it adapts seamlessly, ensuring production that is both fast and reliable.
