# Food-grade LSR Baby Stacking Cups
---
Unlike traditional plastic or foam stacking cups, our LSR baby stacking cups are manufactured entirely from food-grade liquid silicone rubber 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. We specialize in custom and mass production of high-quality LSR products, and these stacking cups are engineered to meet global infant product safety standards while retaining the unique soft, flexible properties of LSR. The core design features a nested set of 8 graduated cups, each with a perforated base that doubles as a bath toy and a standalone play toy, supporting multiple play patterns to encourage early cognitive development.
Our stacking cups are free of BPA, phthalates, lead, PVC, and other common toxic additives banned in infant products, with a non-porous surface that resists bacterial growth even with regular use and exposure to water. The soft LSR construction eliminates the risk of injury from hard impacts or broken edges, making it suitable for unsupervised play (under guardian care) as babies explore and interact with their toys.

Our baby stacking cups are manufactured via precision liquid injection molding, with the following controlled process parameters to ensure consistent product quality:

As a specialist LSR manufacturer, we source only 100% virgin food-grade LSR material for our baby stacking cups, with no recycled silicone or filler additives that can compromise safety. Unlike plastic stacking cups that can leach chemicals when heated or chewed, LSR is chemically inert, so it is safe for babies to chew on during teething stages. The non-porous surface prevents the growth of mold and mildew even when used regularly as a bath toy, a common issue with porous foam or low-quality rubber toys.
The 40 Shore A hardness of our standard LSR stacking cups strikes an ideal balance: firm enough to hold their shape when stacked, but soft enough to prevent injury if a baby falls against the cups or drops them on their feet. The flexible LSR material will not crack, shatter, or produce sharp edges if dropped from high chairs or playpens, unlike hard plastic stacking cups that can break into sharp fragments after repeated impacts.
LSR’s temperature resistance allows our stacking cups to be sterilized via multiple common methods: boiling, steam sterilization, or dishwasher cleaning (top rack) without deforming, degrading, or releasing harmful substances. The smooth non-porous surface wipes clean easily, and does not trap food residue, soap scum, or bath water, reducing the workload for parents and maintaining a hygienic play environment for babies.
LSR has excellent aging resistance, tear resistance, and compression set resistance, so our stacking cups will remain soft, flexible, and shape-stable through years of use. They will not become brittle, sticky, or discolored like low-quality silicone or plastic toys, making them suitable to pass down between multiple children, reducing overall waste.
