Household silicone kitchenware and food containers often raise concerns: unpleasant odors released during high-temperature cooking, easy cracking and damage with prolonged use, production defects due to poor demolding, and increased costs from secondary vulcanization. The IOTA LSR 3620 series secondary-vulcanization-free liquid silicone rubber acts as a "reliable partner" in the food contact field, offering odorless safety, high-temperature resistance, excellent molding performance, and cost savings, satisfying both manufacturers and consumers.

This silicone is exceptionally "foodie-friendly." It complies with BfR and FDA safety standards, making it safe for direct food contact, with extremely low VOC content. Even when heated at high temperatures in a microwave, it releases no harmful substances or odors. The 1:1 mixing ratio is effortless—like mixing "one part juice concentrate with one part water"—requiring no specialized measuring tools. Even non-specialized workers can achieve precise proportions. With a viscosity akin to thick honey, it self-levels after injection into molds, and its demolding performance is outstanding—smooth as a ripe peach sliding out of its skin, with no mold sticking or product deformation. After curing, it achieves moderate hardness, similar to household food-grade silicone spatulas—durable yet flexible enough to scrape bowl residues clean. Its excellent tensile strength resists tearing even under forceful stretching, significantly extending its service life.

In food contact applications, its versatility shines:

• Kitchen silicone spatulas made with it are heat-resistant and odor-free, perfect for mixing batter or scraping pots clean.

• Seal rings for insulated bottles and food containers ensure leak-proof sealing, remaining intact and non-degrading after high-temperature sterilization.

• Baking silicone molds release smoothly, producing cookies and cakes with crisp edges, and can be reused multiple times.

• Baby food silicone molds are safe and non-irritating, suitable for direct contact with purees and mashes, giving parents peace of mind.

• Food-grade silicone ice trays are soft and easy to demold—frozen ice pops out with a twist, minimizing breakage.

Its user-friendly details are noteworthy:
During production, remember to use only A and B components from the same batch. Mix each thoroughly before combining to ensure uniformity.
Store below 23°C—unopened, it has a shelf life of up to 12 months without degradation. Even past this period, a simple performance test can confirm its continued usability.
Its rapid thermal curing (90 seconds at 130°C) eliminates the need for secondary vulcanization, saving manufacturers time and equipment costs. Whether for small-batch trials or large-scale production, it handles both effortlessly.
