Liquid silicone rubber is used in an unending number of appliances and industries. You can find silicone products in the medical field, most scientific landscapes, automotive industries, and consumer goods. Liquid silicone injection molding is a manufacturing procedure used because it has some of the most unique features for all industry landscapes. This inorganic polymer is created by combining silicon, oxygen, carbon, and hydrogen using a chemical chain reaction as the backbone of the substance called siloxane.

Silicone achieves its most perfect form when the formula is spiked with catalysts during the curing process, creating a chemical bond in the backbone called crosslinks. Most manufacturers use platinum and peroxide in the curing process, making liquid silicone injection molding with much improved tensile and tear strength and clear features with enhanced consistency that doesn't leave any type of peroxide residues.

There are many versatile properties in liquid silicone injection molding, and most can be boiled down to the siloxane bond. The siloxane bond helps improve the material's mechanical performance while increasing its strength. This particular chain adds an inorganic backbone that never interacts with biological materials and combines with certain organic chemical groups in the mix.

The inorganic nature of liquid silicone injection molding makes it the best material for medical appliances and skin-based applications. Then there's the possibility of combining the material with chemical groups to increase its robust performance. Silicone has a property named "rebound resilience," which is nothing more than the ability to transfer energy after being hit with specific amounts of force, thus outperforming elastomers and making it an ideal pick for pumping applications.

The General Properties of Liquid Silicone Injection Molding

It's biocompatible

Liquid silicone rubber has some of the most fantastic compatibility properties with human tissue and body fluids. If you compare silicone with other elastomers, you'll see how resistant this material is to bacteria growth without stains or corrosion. The material is hypoallergenic, which is the best option if you need to make skin-contact products.

It's tasteless and odorless

Silicone doesn't have any taste or scent, meaning it can be formulated to follow strict FDA regulations in the medical or food industries.

It's durable

Liquid silicone rubber parts can withstand some of the most extreme temperatures, making the material a top choice for automobile parts and many other outdoor applications.

It's chemical resistant

Liquid silicone never gets a dent from the elements. Water, oxidation, and chemical solutions such as acids can't damage it. The material is easily sterilized using steam autoclaving, ethylene oxide, gamma rays, and other techniques.

It can withstand extreme temperatures

Molded silicone can withstand the most comprehensive range of high to low-temperature extremes, remaining stable to temperatures ranging from -60°C to 180°C without a scratch.

It has great mechanical properties

Liquid silicone injection molding creates products with solid elongation, high tear, and incredible tensile strength, with a hardness range that goes between 4 to 85 Shore A.
