Excellent Anti-Yellowing Property LSR Liquid Silicone Rubber For Nipples

Description

RUI-HE 6250-60® is a kind of two-component liquid silicone rubber for injection molding processes, consisted of part A and part B. It can be used to produce pacifiers and other baby products with high transparent,high tear resistance and good resistance to yellow. All LSR are platinum cured (vulcanized) materials which are mixed in a 1 : 1 ratio by weight.

Mixing ratio of components A : B = 1 : 1.

Vulcanization: 150 °C / 5 min

Liquid Silicone Rubber for general purpose applications.

Producing quality parts rapidly is essential in the LSR molding market. Liquid injection molding provides the most efficient and economically viable process using Liquid Silicone Rubber (LSR). Elkem Silicones offers a robust general purpose product range of LSR materials including durometers from 01-70 Shore A. These materials are specifically designed with a fast cure and excellent mold release as well as excellent physical and mechanical properties.

Liquid injection molding is the process used with liquid silicone rubber (LSR) to fix the material from an uncured state into a cured part.

The highly viscous LSR is extracted from drums or pails using a dosing unit and injected into a closed mold in the press.

The mold is then heated, and the heat combined with pressure applied to the LSR results in the rubber becoming a solid part.

Package & storage:

Packaging and storage are essential considerations for silicone rubber to ensure its quality and longevity. Here are some guidelines for packaging and storing silicone rubber:

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.

FAQ

Is silicone rubber safe for medical applications?

Silicone rubber is known for its biocompatibility and is commonly used in medical and healthcare applications. It is non-toxic and does not cause adverse reactions when in contact with biological tissues or fluids. However, specific medical-grade formulations are required for applications involving direct or prolonged contact with the body.

How is silicone rubber processed?

Silicone rubber can be processed using various techniques, including injection molding, compression molding, extrusion, and liquid injection molding. The choice of processing method depends on the desired product shape, complexity, and volume.

Can silicone rubber be recycled?

Yes, silicone rubber can be recycled, although the process can be more challenging compared to other materials. Some recycling methods involve grinding and reprocessing the material into new silicone products or converting it into other materials like silicone oil.

Does silicone rubber have a shelf life?

Yes, silicone rubber has a limited shelf life. The shelf life 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.

Can silicone rubber be bonded or glued to other materials?

Silicone rubber can be bonded to other materials using specialized adhesives or bonding techniques. Surface preparation and choosing the appropriate adhesive are important factors in achieving a strong and durable bond.
