# Food-grade LSR Baby Shape Sorter Puzzle Toy
Manufactured by 橡楚（湖北）橡胶有限公司
---
The Food-grade LSR Baby Shape Sorter Puzzle Toy is a safety-first early educational play product manufactured by 橡楚（湖北）橡胶有限公司, located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号. Designed for infants aged 6 months to 3 years, this product combines developmental cognitive training with the exceptional biocompatibility of liquid silicone rubber (LSR), addressing common safety concerns of traditional plastic or wood shape sorter toys.
Unlike rigid plastic or porous wood alternatives, our shape sorter is produced entirely from food-grade liquid silicone rubber, a non-toxic, soft elastomer that eliminates choking hazards from sharp edges and splintering. Each puzzle piece and the base board are molded as single-piece solid LSR structures, with no glued joints, added paint, or detachable small parts that can break off during use. The product is designed to help babies develop hand-eye coordination, shape recognition, fine motor skills, and problem-solving abilities through playful exploration, while meeting the strictest safety requirements for infant-use products.
As a professional LSR manufacturer, we leverage precision injection molding technology to ensure consistent dimension tolerance and durable performance, making this shape sorter resistant to repeated drops, bites, and cleaning cycles that are common in infant daily use.

All components of this shape sorter are fabricated from 100% food-grade addition-cure liquid silicone rubber, with the following material properties:
All puzzle pieces are sized to exceed small-part choking test standards (minimum dimension ≥ 45mm) for infant safety.

As a food-grade LSR product, our shape sorter eliminates the core safety risks of traditional materials. Unlike porous wood, LSR does not absorb saliva, milk, or food residue, preventing bacterial and mold growth that can cause gastrointestinal issues in infants. Unlike rigid plastic, the soft, flexible LSR material prevents cuts, bruises, and tooth damage when babies bite or drop the toy during play. All raw materials are sourced from reputable silicone suppliers and tested for harmful substances before production, with zero BPA, phthalates, or toxic additives.
The non-porous surface of LSR allows for quick, thorough cleaning: components can be rinsed with warm soapy water, disinfected with baby-safe cleaning sprays, boiled, or steamed for sterilization, with no degradation of material properties after repeated cycles. LSR’s exceptional elasticity and tear resistance mean the product will not crack, split, or deform even after years of rough handling by infants, retaining its shape and performance far longer than plastic or wood alternatives.
The soft, slightly grippy surface of our 35 Shore A LSR is perfectly matched to the developing grip strength of infants 6–36 months. Unlike slippery plastic or rough wood, the LSR surface allows babies to grasp and maneuver the shape pieces easily, building fine motor skills and confidence during play. The matte texture provides gentle sensory stimulation, supporting healthy tactile development without being overstimulating.
Our precision LIM manufacturing ensures that each shape piece fits snugly into its corresponding cutout without being too tight for a baby’s developing strength. Consistent dimensional tolerances eliminate ill-fitting pieces that can cause frustration, maintaining the ideal balance of challenge and achievement that supports early problem-solving development.

This Food-grade LSR Baby Shape Sorter Puzzle Toy is designed for multiple infant use scenarios:
Important Use Note: This product is designed for supervised play only. While all pieces are sized to exceed choking hazard standards, constant adult supervision is recommended during use for infants under 12 months.

Our standard shape sorter is produced in 35 Shore A, which is the optimal hardness for infant use: soft enough for safe biting and gripping, but rigid enough to hold shape and fit correctly into the base cutouts. We do not recommend softer hardness (below 30 Shore A) for this product, as it may lead to excessive deformation that prevents correct shape fitting. Harder LSR (above 40 Shore A) is not recommended, as it reduces safety during impact and biting.
We currently offer one standard size for retail and bulk purchase:
Custom size and shape adjustments are available for bulk orders, with a minimum order quantity requirement.
All our baby shape sorter products use only food-grade LSR, in compliance with global food contact safety standards. We do not offer industrial or general-purpose LSR grades for infant products, to ensure full compliance with infant product safety requirements.
