In emerging consumer scenarios such as DIY stress relief toys (squishies), slow-rebound toys, and stress balls, the four-dimensional indicators of "food-grade safety — rebound feel — operational convenience — oil-bleeding/stickiness" of materials directly determine product repurchase rate and user experience. Traditional TPR/PU materials, while low-cost, have odors, toxic risks, and prone to aging and oil bleeding, failing to meet food contact requirements. Ordinary condensation-cure silicones, while soft, release alcohol/acid by-products during curing, causing odors and poor storage stability. More critically, contact with sulfur, phosphorus, or nitrogen compounds causes "vulcanization poisoning", resulting in sticky uncured surfaces. Some addition-cure liquid silicones, while food-grade, have high viscosity and require professional vacuum equipment for defoaming, making them difficult for DIY users to operate. With the explosion of the "stress relief economy", consumer demands for "food-grade safety, creamy softness, self-defoaming without vacuum, dry and non-sticky" squishy materials continue to upgrade. Sourcing a liquid silicone with "1:1 AB mix, ultra-low viscosity, strong self-defoaming, 30x compression ratio, platinum-catalyzed food grade" has become the core proposition for domestic DIY material autonomy.
Addressing this,
Anhui IOTA Silicone Oil Co., Ltd. officially launches
IOTA LSR 3100N Series Food Grade Toy Kneading Liquid Silicone Rubber. Characterized by "two-component platinum-catalyzed silicone elastomer; hardness: creamy (customizable); viscosity: 400-600 CS; curing: 2-3 hours at 25°C (customizable); color: translucent or custom; feel: dry, non-sticky, no oil stains; elongation: >500%; ratio: AB=1:1 (customizable); non-dangerous goods, sealed cool storage, shelf life 1 year", backed by "platinum-catalyzed food grade + ultra-low viscosity strong self-defoaming + 30x compression airy feel", it serves as the "soft bounce choice" for stress relief toys,
achieving the leap from "traditional materials with odor, oil bleeding, and difficult operation" to "platinum self-defoaming food-grade soft bounce".
System Positioning: Addition-Cure Platinum LSR vs. Condensation-Cure Silicone / TPR / PU
IOTA LSR 3100N Series belongs to the addition-cure platinum-catalyzed liquid silicone rubber system, distinct from condensation-cure silicone, TPR, and PU. Condensation-cure silicone releases by-products, has odors, and suffers vulcanization poisoning from sulfur/phosphorus/nitrogen, causing surface uncured. TPR/PU are non-food-grade, prone to oil bleeding and aging. Ordinary addition-cure silicones have high viscosity and require vacuum equipment. Platinum curing achieves by-product-free crosslinking through hydrosilylation, food-grade and odorless, while ultra-low viscosity grants strong self-defoaming ability, thoroughly avoiding the shortcomings of traditional materials.
Molecular Architecture: Platinum-Catalyzed Addition Network + Ultra-Low Viscosity Self-Defoaming Fluid + High Elongation Soft Elastic Body
The core competitiveness of IOTA LSR 3100N Series stems from the precision molecular design of its addition-cure liquid silicone:
-
Platinum-Catalyzed Addition Network: After mixing AB components 1:1, platinum catalyst initiates hydrosilylation between vinyl and Si-H bonds, forming a by-product-free, odorless high-purity crosslinked network. Food-grade safe, suitable even for infant chewing.
-
Ultra-Low Viscosity Self-Defoaming Fluid: Viscosity only 400-600 CS, excellent fluidity after mixing. Strong self-defoaming ability allows bubbles to escape naturally, requiring no professional vacuum equipment. DIY users can simply stir and pour into molds.
-
High Elongation Soft Elastic Body: Elongation >500%, combined with over 30x compression ratio, gives the material "ultimate airy feel" and "resistance-free rebound", instantly restoring after squeezing, providing an immersive stress-relief experience.
Performance Leap: From "Odorous, Oily, Hard to Operate" to "Platinum Self-Defoaming Food-Grade Soft Bounce"
Introducing IOTA LSR 3100N Series brings a qualitative leap to stress relief toy manufacturing:
-
Food-Grade Safe and Odorless: Platinum curing produces no by-products, meeting food-grade requirements, odorless and safe for infants.
-
30x Compression Airy Feel: Over 30x compression ratio, moderate rebound speed, resistance-free and easy to rebound, providing a unique "airy" squeezing experience.
-
Self-Defoaming, No Vacuum Needed: Ultra-low viscosity + strong self-defoaming allows direct pouring after mixing, lowering DIY barriers without professional equipment.
-
Dry and Non-Sticky: Dry feel, non-sticky to hands, no oil stains, completely告别 the pain point of traditional silicone oil bleeding.
-
Easy Demolding, User-Friendly: Easy demolding, molds reusable after cleaning, improving production efficiency.
-
Flexible Customization: Translucent or custom colors, compatible with pigment pastes for personalized appearance; hardness and curing time customizable.
Application Penetration: From DIY Squishies to Creative Handicrafts
The application boundary covers all scenarios requiring "food-grade soft bounce + self-defoaming easy operation":
-
DIY Stress Relief Toys (Main Battlefield): Squishies, slow-rebound toys, stress balls, providing immersive stress relief experience.
-
Creative Handicrafts: Custom toys, blind box figures, stress-relief ornaments, meeting personalized creation needs.
IOTA Technical Guide: Mold Cleaning, Mixing and Pouring
-
Application: Mix AB components 1:1 by weight, stir in one direction; natural defoaming or vacuum 10-30 min; pour into clean mold and cure at room temperature for 2-3 hours (operation time about 1 hour, fully cured in 3x operation time).
-
⚠️ Taboo: Strictly prohibit contact with condensation-cure silicone, sulfur, phosphorus, nitrogen compounds, otherwise vulcanization poisoning causes surface uncured; if condensation molds were used before, thoroughly clean with white oil or solvents; avoid high temperature and direct sunlight.
-
Storage: Non-dangerous goods, sealed cool storage, protect from rain and direct sunlight; shelf life 1 year.
-
Handling: For coloring, use electric mixer to blend pigment with Part A; demold with 3%-5% detergent water, mold reusable without re-cleaning.
Industry Insight: In DIY stress relief materials, the molecular design of addition-cure liquid silicone — "platinum-catalyzed by-product-free + ultra-low viscosity self-defoaming + high elongation soft bounce" — is the key path to achieving the trinity of "food-grade safety + ultimate airy feel + vacuum-free operation" —
the introduction of platinum catalyst solves the industry pain point of condensation silicone: "odorous, poisoning risk", while 400-600 CS ultra-low viscosity ends the application shortcoming of traditional addition-cure: "requiring professional vacuum equipment". IOTA LSR 3100N Series, with "food-grade + 30x compression + self-defoaming + elongation >500% + non-dangerous goods" hard metrics,
fills the key supply chain link for domestic DIY stress relief toy liquid silicone in food safety, operational convenience, and tactile experience, providing a mass-producible high-performance material for downstream toy manufacturers and DIY creators. This confirms that domestic liquid silicone is leaping toward "condensation-cure → ordinary addition-cure → platinum self-defoaming soft bounce", with growing technical say in emerging consumer material fields.
