Food-grade Liquid Silicone Rubber (LSR) baby stacking blocks are soft, safety-focused developmental toys designed for infants aged 6 months and above. As a specialized 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, 橡楚（湖北）橡胶有限公司 produces these stacking blocks using 100% virgin food-grade liquid silicone rubber, engineered to meet strict infant product safety requirements while supporting early cognitive and motor skill development.
Unlike traditional plastic or wooden stacking blocks, our LSR baby stacking blocks feature a flexible, non-slip surface that is gentle on emerging teeth and sensitive gums, while remaining durable enough to withstand repeated biting, chewing, and dropping. Each block is molded as a single seamless piece to eliminate choking hazards from loose parts or adhesive, and engineered with interlocking shapes that are easy for small hands to grasp, stack, and sort. This product prioritizes infant safety above all: it is free from BPA, phthalates, PVC, lead, and other regulated harmful substances, making it a reliable choice for parents and toy brands targeting early childhood development.
The 30 Shore A hardness of this product delivers an ideal balance of softness and structural stability: it is flexible enough to absorb impact when dropped, preventing injury to infants and damage to household surfaces, while retaining enough rigidity to hold its stacked shape without collapsing under the weight of a full 6-8 block tower.
All our food-grade LSR baby stacking blocks are produced from raw materials tested for food contact, with no added fillers or recycled silicone. The single-piece seamless molding process eliminates gaps where bacteria, mold, or food residue can accumulate, reducing the risk of contamination for infants. We test every production batch for harmful substance content to ensure compliance with global infant product safety regulations, giving both brand partners and end consumers full confidence in product safety.
The 30 Shore A hardness specified for this product is tailored to infant use: it is soft enough to cushion falls and soothe teething discomfort, eliminating the risk of injury from hard plastic or wooden blocks if an infant falls onto the toy or drops it on their foot. At the same time, it provides enough resistance to help infants build fine motor skills as they grasp, stack, and manipulate the blocks. The non-slip matte texture improves grip for wet or small hands, making it easier for younger infants to use independently.
LSR material is highly resistant to wear, tear, and discoloration, so our stacking blocks retain their softness and shape even after years of use and repeated sterilization. Unlike foam blocks, they do not absorb water, crumble, or develop mildew, and unlike plastic blocks, they do not become brittle or crack with extended use. Cleaning is simple: blocks can be rinsed with soap and water, boiled for deep sterilization, or run through the top rack of a dishwasher without damage.
As an OEM/ODM LSR product manufacturer, we support custom requests for shape, size, color, and set configuration to meet the specific requirements of toy brands and retailers. All colorants used are food-grade, non-bleeding, and resistant to fading, even with repeated exposure to heat and cleaning products.
Our Food-grade LSR Baby Stacking Blocks are primarily designed as infant developmental toys for domestic and commercial use, with common applications including:
All products can be supplied as bulk raw molded components for brand finishing, or as fully packaged finished products ready for retail distribution.
This specific product line is manufactured at 30 Shore A, which is the most popular hardness for baby stacking blocks. For partners seeking alternative hardness for specific use cases: we offer 20 Shore A (extra soft for sensitive teething) and 40 Shore A (firmer for larger block sets) upon request, with all other food-grade safety properties retained.
We offer three standard size configurations for standard stacking block sets:
Custom sizes and non-square shapes (including circular, triangular, and animal-shaped blocks) are available for OEM orders.
All our baby stacking blocks use only food-grade LSR, as required for infant products. We do not offer industrial or non-food grade material for this product category, to ensure consistent compliance with global infant product safety regulations.
At 橡楚（湖北）橡胶有限公司, we implement a full quality management system certified to ISO 9001, covering raw material inspection, in-process production monitoring, and finished product testing before shipment. Every batch of food-grade LSR baby stacking blocks undergoes:
We maintain full traceability for all raw materials and production batches, to support our partners’ regulatory reporting requirements.
