This specialized platinum silicone is engineered for the production of multi-layer squishy items that replicate realistic snacks, desserts, and baked goods. It enables manufacturers to create products with a soft, slow-rising interior encapsulated by a slightly firmer, painted, or pigmented outer layer—mimicking the structure of real bread, macarons, filled cookies, and chocolate-dipped treats.
The system consists of two matched components: an ultra-soft core silicone and a slightly harder skin silicone, both using the same addition-cure chemistry for perfect interlayer adhesion. The core material cures to a Shore 00 hardness below 10, giving the finished product a deeply satisfying, marshmallow-like squish. The outer layer, at approximately Shore A 3–5, is firm enough to accept paint details, resist abrasion, and hold fine decorative elements like frosting lines or sugar grain textures.
Because both layers are platinum-catalyzed, they cure without shrinkage mismatch, ensuring no delamination even after extensive use. Their working times are synchronized to allow sequential pouring into the same mold, and full cure can be achieved at room temperature or with gentle heating. The silicone accepts a wide range of food-safe pigments and specialty effect powders (e.g., matte, shimmer, glow-in-the-dark) to achieve eye-catching visual appeal.
This product complies with toy safety directives and is free of latex, phthalates, and other restricted substances, making it suitable for children’s products and adult collectible markets alike. The non-stick nature of the cured rubber simplifies demolding and reduces the need for release agents that could leave residues. For brands looking to differentiate their squishy line with realistic, multi-texture bakery items, dessert keychains, or interactive play food, this dual-layer silicone system offers design flexibility, production reliability, and the authentic slow-rising feel that keeps
