Solid Silicone Rubber Nipples VS Liquid Silicone Rubber Nipples
--- Solid Silicone Rubber Nipples
Advantages:
Stable Quality:
Made using safe and environmentally friendly production processes, food-grade solid silicone rubber is highly transparent and odorless. It meets stringent inspection standards such as EN14350-2, contains 0% Bisphenol A (BPA), and has stable and reliable material properties.
Strong Durability:
It can withstand repeated exposure to high temperatures (resistant to low temperatures as low as -60°C and high-temperature sterilization up to 310°C), high pressure, boiling, microwave sterilization, and chemical disinfectants. It is resistant to long-term chewing by infants and has a long service life.
Stable Flow Rate:
With moderate softness and hardness, the nipple opening does not change during sucking, ensuring a stable milk flow. This effectively prevents babies from choking due to drinking too quickly.
Lower Cost:
Compared to liquid silicone rubber nipples, the production process for solid silicone rubber nipples involves lower mold-opening costs. Custom molds can be made based on different design requirements from customers.
Disadvantages:
Less Soft:
The softness of solid silicone rubber nipples is slightly inferior to liquid silicone rubber nipples. The texture may not mimic the feel of a mother's nipple as closely, impacting comfort.
--- Liquid Silicone Rubber Nipples
Advantages:
High Softness:
Extremely soft texture closely resembles the feel of a mother's nipple. Babies feel more comfortable during sucking as the nipple conforms better to the shape of the oral cavity. It allows for natural latching and deforms appropriately during sucking.
Good Elasticity:
Excellent elasticity recovery ensures the nipple quickly returns to its original shape after use. It maintains its form and function even after multiple uses and is less likely to be bitten or torn by the baby.
High Safety:
With excellent chemical stability, LSR is an inert material that does not react with baby food. It is non-toxic and complies with stringent food safety standards such as FDA food contact material standards and EU regulations. It is free from harmful substances like BPA.
Easy to Clean:
Its smooth surface does not easily attract dirt or milk residues. It can be cleaned effectively with water or baby bottle cleaning agents. The smooth surface also discourages bacterial attachment and growth, maintaining hygiene.
Disadvantages:
Easily Damaged:
Compared to solid silicone rubber nipples, liquid silicone rubber nipples are softer and more prone to being chewed or torn by playful babies.
Flow Rate Variation:
During feeding, the nipple opening may enlarge due to sucking, leading to an unstable milk flow and increasing the risk of choking.
Higher Cost:
The production process requires higher technical standards and specialized equipment, with mold-opening costs running into tens of thousands. This results in higher production costs and product prices for liquid silicone rubber nipples.
