# Food-grade LSR Infant Early Education Learning Board
---
The Food-grade LSR Infant Early Education Learning Board from 橡楚（湖北）橡胶有限公司 is a safety-first sensory learning tool designed specifically for infants aged 6 months to 3 years, manufactured with 100% food-grade liquid silicone rubber (LSR) to meet the strictest infant product safety requirements. As a professional LSR product manufacturer based in 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, we prioritize infant safety and developmental value in every step of our production process, resulting in a durable, non-toxic learning board that supports core early childhood developmental milestones.
This learning board integrates sensory stimulation, fine motor skill practice, and basic cognitive learning into one ergonomic product. Unlike traditional plastic or foam learning boards, our LSR construction delivers consistent softness that eliminates risk of impact injury during active play, while retaining enough shape stability to hold embedded learning elements securely. Every surface and edge of the board is smoothly finished to avoid scratches or irritation to delicate infant skin, and the non-porous material resists the growth of bacteria, mold, and mildew even with regular use and exposure to saliva or food spills.
Our product is designed to accommodate common early education content including sensory texture patches, shape sorter cutouts, number and letter recognition inserts, and tactile exploration areas. Custom content layouts are available to align with different developmental stages and educational frameworks, all manufactured using our precision injection molding process to ensure tight tolerances and consistent quality across every production run.

Unlike many competing infant learning boards that use lower-grade silicone or plastic coatings, our entire product is manufactured from pure food-grade LSR that is safe for infants to chew, suck, and bite during normal teething and exploration. The non-porous molecular structure of LSR prevents bacterial absorption, making it far easier to keep clean than porous wood, foam, or plastic alternatives. All raw materials are tested prior to production to confirm the absence of BPA, phthalates, lead, and other harmful restricted substances, aligning with global infant product safety regulations.
Food-grade LSR has exceptional elasticity and tear resistance that outperforms many other materials used for infant learning products. It will not crack, warp, or become brittle with long-term use, even when exposed to frequent cleaning, temperature fluctuations, or rough handling by infants. Unlike rigid plastic boards, our LSR construction absorbs impact when a child drops the board or falls against it, significantly reducing the risk of injury compared to rigid alternatives. The material also resists stains from food, juice, and cleaning products, retaining its appearance and function for years of use.
The soft, matte texture of our LSR learning board provides gentle, consistent sensory stimulation that supports infant tactile development. We can integrate custom textured LSR inserts directly into the board during molding, eliminating loose parts that pose a choking hazard, while creating varied sensory experiences for exploring infants. The inherent non-slip properties of LSR keep the board stable on flat surfaces during play, reducing sliding and making it easier for young children to manipulate the board’s features independently.
The non-porous surface of LSR can be easily wiped clean with soap and warm water, disinfected with a mild bleach solution, or even boiled for deep sterilization without damaging the material or causing leaching of harmful substances. This is a critical advantage for infant products that require regular sterilization to prevent the spread of germs, especially when multiple children use the board in daycare or playgroup settings. Unlike wood, LSR will not absorb moisture or warp after repeated washing or sterilization.

Our Food-grade LSR Infant Early Education Learning Board is suitable for a wide range of early education and care settings, including:
* Home use: For parent-led early education supporting sensory development, fine motor skills, shape and color recognition, and basic number/letter literacy for infants and toddlers. The soft, safe construction is ideal for unsupervised (adult-supervised) play, as it eliminates many of the safety hazards associated with rigid learning boards.
* Childcare centers and nurseries: The durable, sterilizable material meets the strict hygiene requirements of group childcare settings, and can withstand frequent use by multiple children. Custom bulk orders can be produced with consistent layouts aligned to center developmental curricula.
* Early intervention therapy: The varied sensory properties and customizable functional design make the LSR learning board suitable for use in occupational therapy and developmental intervention for infants with fine motor or sensory processing differences.
* Retail infant product brands: We offer OEM manufacturing for infant product brands looking to add a high-quality, safe LSR learning board to their product line, with custom branding, layout, and size options available to meet your specific market requirements.

We offer three standard hardness options to align with different use cases:
* 25 Shore A: Extra soft for teething infants, ideal for products that include chewable elements; provides maximum sensory softness.
* 30 Shore A (standard): Balances softness and shape stability, suitable for most standard learning board designs with embedded shape sorters and textured inserts.
* 40 Shore A: Firmer construction for larger boards or designs that require extra shape retention for sliding or moving functional elements.
We offer two standard stock sizes, with custom sizes available for OEM orders:
* Small (200mm × 300mm): Ideal for home use and easy storage, suitable for 6-12 month old infants focused on basic sensory exploration.
* Large (300mm × 400mm): Standard size for full learning layouts with multiple cognitive elements, suitable for 12-36 month old toddlers.
* Custom sizes up to 600mm × 800mm can be manufactured for group use or multi-activity board designs.
All of our infant learning boards use the same food-grade LSR material, compliant with global food contact and infant product safety standards. We do not offer lower-grade non-food material for this product line, to ensure consistent safety across all our infant-focused LSR products.
