# Food Grade LSR Baby Ring Stacking Toy
---
Food Grade Liquid Silicone Rubber (LSR) baby ring stacking toys are soft, safe developmental play products designed for infants aged 3 months and above, manufactured by 橡楚（湖北）橡胶有限公司. As a specialist 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 leverage precision LSR injection molding technology to produce stacking rings that meet strict food contact safety standards, combining developmental benefits with uncompromising safety for young children.
Unlike traditional plastic or wood stacking toys, our LSR baby ring stacking toys are crafted entirely from food-grade liquid silicone rubber, delivering a soft, chewy texture that soothes teething discomfort while supporting early motor skill development. Each set includes 5–6 graduated soft rings that fit onto a stable base, encouraging infants to practice hand-eye coordination, color recognition, and size differentiation through interactive play. Our production process adheres to consistent quality standards aligned with our ISO 9001 certification, ensuring every product batch meets global food contact safety requirements for infant products.
Core selling points of our Food Grade LSR Baby Ring Stacking Toy include 100% food-grade LSR material composition, non-toxic formulation, soft impact-resistant design, easy sterilization, and durable long-term use for everyday infant play.

Our baby stacking rings are produced entirely from food-grade LSR sourced from reputable raw material suppliers, with zero BPA, phthalates, PVC, or harmful plasticizers common in traditional infant toys. The fully cross-linked LSR formulation does not leach chemicals into the mouth when infants chew or suck the rings, making it safe for daily teething use and meeting the strictest global safety regulations for infant products.
At a Shore A hardness of 30, our LSR stacking rings have a gentle, flexible texture that absorbs impact during play. Unlike hard plastic or wooden rings, they will not scratch infant gums, damage developing teeth, or cause injury if a child drops the toy on themselves or falls against it. The soft matte surface also provides superior grip for small, uncoordinated hands, helping infants successfully grasp and stack the rings to build confidence.
LSR is a non-porous material that resists the buildup of bacteria, mold, and mildew, unlike porous foam or fabric toys. Our stacking rings can be sterilized via multiple convenient methods: boiling, steaming in a bottle sterilizer, dishwasher top-rack cleaning, or wiping with food-grade disinfectant. The material retains its physical properties and color after repeated sterilization, with no cracking, deformation, or fading.
High-quality LSR has excellent aging resistance, UV stability, and resistance to repeated bending and flexing. Our stacking rings do not become brittle, sticky, or discolored with regular use and cleaning, maintaining their soft texture and safety for years through multiple stages of infant development and even reuse for subsequent children.

Our Food Grade LSR Baby Ring Stacking Toy is designed as a versatile developmental infant product, with primary applications including:

We offer a standard hardness of Shore A 30 for most use cases, which balances softness for chewing and sufficient structural rigidity to hold shape when stacked. For customers seeking an extra-soft teething-focused variant, we can produce a 20 Shore A hardness variant to meet specific product positioning requirements.
Our standard full set includes 6 graduated rings with inner diameters ranging from 45 mm to 90 mm and outer diameters ranging from 60 mm to 120 mm, paired with a circular LSR base 130 mm in diameter. We accept custom size adjustments for bulk orders to match specific packaging or product design requirements, with minimum order quantities applied for custom dimensions.
All our LSR baby stacking toys are produced exclusively in food-grade material in compliance with FDA and EU food contact standards. We do not offer lower-grade non-food material for this product category, to ensure consistent safety for all infant users. Custom color matching is available for bulk orders to match brand color schemes, using only approved food-grade pigments.
