Baby Feeder Spoon and Nipples Liquid Silicone Rubber Food Grade LSR
RH6250-50A/B is platinum cured silicone rubber for silicone products.
The silicone rubber is a two-component liquid silicone rubber for injection moulding processes.
The pot-life of the mixture of the two components (closed vesssel) at 20℃ is 5 days. Increased temperatures reduce the pot-life.
Typical Properties: Food Grade Silicone rubber for baby products

Packaging & Storage
Packaging: Silicone rubber is typically packaged in sealed containers or bags to protect it from contaminants and moisture. The packaging should be airtight to prevent exposure to air and humidity, which can affect the material's properties.
Moisture protection: Silicone rubber is sensitive to moisture, so it is crucial to keep it dry during storage. Consider using moisture-proof packaging materials such as moisture barrier bags or desiccant packs to absorb any moisture that may be present.
Temperature control: It is recommended to store silicone rubber in a temperature-controlled environment. Ideally, the storage temperature should be between 10°C and 30°C (50°F and 86°F). Avoid extreme temperature fluctuations, as they can affect the material's performance and shelf life.
Light protection: Silicone rubber should be protected from prolonged exposure to direct sunlight or UV radiation, as it can cause degradation. Store the material in a dark or opaque container to shield it from light.
Shelf life: Silicone rubber has a limited shelf life, which can vary depending on the specific formulation and manufacturer. It is advisable to check the product datasheet or consult the manufacturer for the recommended shelf life and storage conditions. Using silicone rubber past its expiration date may result in decreased performance or quality issues.
First-in, first-out (FIFO): When storing multiple batches or containers of silicone rubber, it is best practice to follow the FIFO principle. Use the oldest stock first to minimize the risk of material degradation and ensure freshness.
Avoid contact with incompatible materials: Silicone rubber should be stored separately from materials that can react with it or cause contamination. Keep it away from solvents, oils, acids, and other chemicals that may affect its properties.
Handling precautions: When handling silicone rubber, use clean gloves or tools to prevent contamination. Avoid touching the material with bare hands, as oils and dirt can affect its performance.
FAQ
Q: Does silicone release PCBs during curing?
A: There is a possibility that certain compounds (usually those used for extrusion purposes) can evolve very low quantities of PCB''s.
These are derived from the peroxide used to cross-link the silicone. It is therefore wise to ensure that adequate ventilation and
extraction is provided in the areas where such compound is being processed.
Q: Can I thicken a silicone?
A: Silicone liquids can be thickened to a certain extent by the addition of silicas.
