TPE Food-Grade Ice Cube Tray Specialized Material

Core Advantages​

•Food-grade certification, safe and risk-free: Adopts a full food-grade formulation system, selects high-purity food-grade SEBS base material and food-grade additives, halogen-free, non-toxic, odorless, and no harmful leaching. Strictly controls harmful components such as bisphenol A (BPA), phthalates, heavy metals, and plasticizers. Extremely low migration potential effectively prevents the migration of small molecules when in contact with water, juice, and other foods. Complies with national food contact plastic and rubber material safety standards such as GB 4806.7-2016 and GB 4806.11-2016. Also passes authoritative domestic and international food-grade certifications including FDA, REACH, EN71, IEC 61249-2-21. Undergoes strict third-party testing, focusing on key items such as total migration, potassium permanganate consumption, heavy metals, and decolorization tests. Compliant and traceable, can directly contact various foods, suitable for use by all age groups including the elderly and children, eliminating food contact safety hazards at the source.​

•Excellent low-temperature resistance, remains unchanged when frozen: Specifically optimized low-temperature resistant formulation, temperature resistance range covers -60°C to 80°C, can be stored and used long-term in freezer compartments (-18°C to -25°C). Does not become brittle, crack, or harden in low-temperature environments. Maintains good softness and toughness after repeated freezing and thawing (withstands ≥1000 freeze-thaw cycles), with no damage or odor leaching. Does not age or degrade in performance due to temperature changes, suitable for the core scenario of long-term freezing use in ice cube trays. Also withstands cleaning with room temperature and warm water, handles alternating high and low temperatures without issue, solving the pain point of traditional materials being prone to cracking at low temperatures.​

•Soft and easy to demold, more convenient to use: Hardness can be flexibly customized (Shore 0–30A), texture is soft, chewy, and elastic with a fine touch, possessing excellent elastic recovery. After ice cubes are formed, gentle squeezing allows quick demolding without tools, no sticking to ice, no residue, completely solving the problems of traditional hard ice cube trays being difficult to demold, prone to sticking to ice, and easily damaged. The surface also features a non-stick design, further enhancing demolding convenience, balancing soft touch with practical usability, making ice cube tray use more worry-free, suitable for scenarios such as home DIY ice cube trays and commercial batch ice making.​

•Easy to clean and maintain, hygienic and convenient: The material surface is smooth and dense, not prone to harboring dirt or breeding bacteria. Daily residues such as water stains or juice can be easily rinsed with water or wiped clean with a soft cloth, no complex cleaning process required. Also has good chemical resistance, can withstand common food cleaners, does not soften, become sticky, or leach harmful substances after cleaning, does not affect material performance or food contact safety, facilitates daily maintenance, ensures hygiene in use, meeting the hygiene requirements of food contact products.​

•Aging and wear resistant, durable: Added food-grade anti-aging additives, combined with the excellent toughness of SEBS base material, tensile strength can reach 2–5 MPa, elongation ≥700%, outstanding tear and damage resistance, can withstand long-term repeated squeezing, freezing, and cleaning without damage, cracking, or flaking. Dense surface resists yellowing and fading, does not age or degrade when long-term exposed to water, food, and freezer environments, effectively resists various types of wear in daily use, extends ice cube tray lifespan, reduces replacement frequency, lowers usage costs and waste. Also has excellent dynamic fatigue resistance, suitable for long-term repeated use scenarios.​

•Easy to process, high molding efficiency: Excellent and stable melt fluidity, uniform plasticization, no melt fracture, can be quickly molded via processes such as injection molding and compression molding, smooth molding without material accumulation or flash, product surface is flat and smooth, no burrs or bubbles, low shrinkage rate (≤0.5%), precise dimensions, adaptable to various ice cube tray shapes (square, round, cartoon shapes, etc.), no need for subsequent grinding or trimming, processing is convenient and efficient. Raw material contains no moisture, can be used directly without drying, saves energy, sprue material can be 100% recycled without affecting product physical properties, further reduces production costs, meets manufacturers' large-scale production needs. Also bonds well with substrates such as PP, suitable for composite ice cube tray production.​

•High adaptability, customizable needs: Can flexibly adjust hardness, softness, color, and surface texture based on ice cube tray use (home, commercial) and design. Can customize various styles such as transparent, translucent, macaron colors, solid colors, etc., uniform coloring, good stability, uses food-grade color masterbatch, not prone to fading or migration, no harmful leaching, bright and soft colors enhance ice cube tray aesthetics, suitable for different home styles and DIY needs. Also can customize exclusive formulations such as high softness, high low-temperature resistance, easy demolding, etc., suitable for different product types such as ordinary ice cube trays, silicone-texture ice cube trays, foldable ice cube trays, etc. Can replace traditional hard plastics and ordinary silicone materials, solving their pain points of difficult demolding, easy damage, and odor, providing designers with greater design freedom, meeting the aesthetic and practical needs of modern ice cube tray products.​

•Halogen-free and environmentally friendly, aligns with green concepts: Uses halogen-free, environmentally friendly formulation, halogen-free, non-toxic, odorless, complies with global green production and eco-friendly consumption trends, recyclable and reusable, reduces plastic pollution, balances food safety and environmental needs. The material itself has no irritating odor, does not release harmful gases during production and use, ensuring human health and meeting environmental production standards, suitable for manufacturers and consumers focused on environmental protection, an ideal choice to replace traditional non-eco-friendly ice cube tray materials.
