# Food-grade LSR Infant Sensory Ball
---
The Food-grade LSR Infant Sensory Ball from Xiangchu (Hubei) Rubber Co., Ltd. is a specially designed infant development toy manufactured from 100% raw liquid silicone rubber (LSR) that meets global food contact safety standards. Developed to support early sensory and motor skill development in infants aged 3 months and above, this sensory ball combines soft, flexible texture with textured surface patterns to engage a baby’s sense of touch, sight, and fine motor control.
Unlike conventional plastic or natural rubber infant toys, our LSR sensory ball is engineered to be completely non-toxic, odorless, and resistant to repeated cleaning and sterilization. It retains its soft shape and textured grip through years of use, without cracking, discoloring, or leaching harmful chemicals. Each ball is produced in our facility located at No. 54, Neihe Alley, Fankou Street, Economic Development Zone, Echeng District, Ezhou, Hubei Province, China, under strict process controls aligned with our ISO 9001 quality management system.
The core design objective of this product is to balance safety with developmental function: the textured, bumpy surface provides gentle tactile stimulation to help infants recognize different textures, improve hand-eye coordination, and encourage crawling and grasping practice. It is also lightweight enough for small hands to hold, and bounces gently to maintain a baby’s engagement during play.

The Food-grade LSR Infant Sensory Ball is manufactured via liquid injection molding, with the following controlled process parameters to ensure consistent quality:
---
Unlike many mass-market infant toys that use lower-grade silicone or plastic, our sensory ball is produced from pure food-grade LSR with no added fillers, recycled materials, or harmful chemical additives. It will not release toxic substances even if an infant chews or sucks on it during teething, making it safe for unsupervised (with caregiver observation) play. The non-porous surface of LSR also resists bacterial growth better than porous rubber or plastic, reducing the risk of contamination during repeated use.
Addition-cured LSR has excellent anti-aging, ozone, and UV resistance, so our sensory ball will not become brittle, sticky, or discolored even after 2+ years of regular use and frequent sterilization. It retains its softness and resilience far better than conventional plastic balls, which often crack or lose shape after exposure to high-temperature sterilization. This durability allows the product to be reused for multiple children, reducing long-term waste.
With a Shore A hardness of 21 HA, the sensory ball provides the ideal balance of softness and support: it is gentle enough that it will not injure an infant’s gums or skin during chewing or accidental impact, yet firm enough to maintain its shape for bouncing and rolling activities. The evenly distributed raised bumps provide consistent tactile stimulation that helps promote sensory integration, and the texture also creates enough friction for small, wet hands to grip easily.
Our LSR sensory ball withstands repeated boiling, steam sterilization in electric sterilizers, and cold sterilization with infant-safe disinfectants without degradation. Unlike many plastic toys that warp or release chemicals after high-temperature sterilization, the LSR material remains stable and intact, simplifying routine cleaning for caregivers.

The Food-grade LSR Infant Sensory Ball is designed for a wide range of infant and early childhood use cases:
---
Our standard sensory ball is produced at a Shore A hardness of 21 HA, which is optimized for most infants aged 3 months and above. For customers requiring custom hardness, we offer adjustments between 15 HA and 30 HA to meet different regional preferences: lower hardness (15-18 HA) is softer for teething use, while higher hardness (25-30 HA) provides greater bounce for active play.
The standard product diameter is 70mm, which is ideal for small infant hands to grasp and hold. We also offer custom sizes ranging from 50mm (for younger infants 0-3 months) to 100mm (for group play for toddlers 18+ months) to meet different product positioning and use case requirements.
Our standard offering is food-grade LSR that meets FDA and EU food contact standards, which is suitable for all global markets. We do not offer non-food-grade material for this infant product, as all of our infant LSR products adhere to the strictest safety requirements for infant contact.
