Properties of Silicone

Silicone is an elastomer composed of silicon, carbon, hydrogen, and oxygen. Depending on your chosen formulation, silicone may also contain other fillers. These additions are included to try and improve certain properties or reduce the overall cost of your production. Due to these variations, the exact properties of silicone rubber will depend on the type you select for your order. Call REDCO at 775-882-3100 today to learn more.

Silicone Rubber Characteristics

Silicone rubber outshines other varieties of rubber in many applications due to its high-performance characteristics, such as:

Specific Gravity: .95
Tensile Strength, PSI—Pure Gum: 500
Tensile Strength, PSI—Reinforced: 1200
Practical Shore A Hardness Range: 20-80

Benefits of Silicone Material

Versatile and tough, silicone can stand up to a variety of environmental factors. It features fast curing, a low compression set, and delivers parts with long operational lifespans. Other advantages of silicone rubber include:

Excellent atmosphere aging, oxidation, heat, and moisture resistance
Excellent low temperature flexibility
Excellent dielectric properties
Good compression set
Good permeability
Good resistance to flame, diluted acid, oxygenated solvents, and animal or vegetable oil
Fair heat, tear, and abrasion resistance
Fair resistance to hydrocarbons, oil, and gasoline

Silicone’s Limitations

For most productions, cost is the leading limitation for choosing silicone. Due to this rubber's advanced features and versatile characteristics, it tends to be more expensive than other materials. It also has poor tear strength, which can be addressed with additives. Always be sure to work with a reliable developmental laboratory like REDCO when working with custom rubbers or elastomer compounds.

Silicone rubbers are generally attacked by solvents, oils, concentrated acids, and dilute sodium hydroxide. If your application involves these substances, a different rubber material will be required for production.

Industrial Applications for Silicone Rubber

Used across virtually every industry, silicone rubber is a high-performing, hypoallergenic, and biocompatible choice for parts used for automotive operations, consumer goods, electronics, medical devices, and other productions. Common components include:

Rubber rollers
Gaskets and seals
Coatings and sealings
Cooking utensils and tools
Adhesives
Food molds
Medical tubes and valves
Goggles and mouthpieces
And much, much more!
