Choosing a Material for a Rubber Injection Molded Project

Which Rubber Material Should I Choose For My Injection Molding Project?

For rubber injection molded products, you will have to take in a number of factors when choosing the best material for the job. Of all the different types of rubber materials, synthetic or non-synthetic, if you want the best performance out of your product you will have to know some of the basic characteristics of these common rubber materials.

Natural Rubber

Natural rubber is the original rubber material, grown from the rubber tree known as Hevea brasiliensis. Natural rubber has been harvested and used for molded products for as long as 3600 years ago by humans.
Natural rubber is a great choice for automotive gaskets and seals. Where natural rubber may be less than sufficient compared to other rubber is in its comparably lower resistance to certain chemicals, oils, sunlight, and the environment.

Silicone is another type of rubber material good for injection molded parts. Silicone offers the same benefits of natural rubber, but it is also able to provide superior resistance to chemicals as well as resilience in high and low temperatures. You can find silicone in many rubber components in automobiles.

Fluorosilicone

Compared to natural rubber and silicone, fluorosilicone is typically used for applications in more extreme conditions, such as strong forces and exposure to fuel and oil. Fluorosilicone is found in many components in the automotive and aerospace industries. Its properties include high versatility, strength, and fuel/oil resistance.

FDA Silicone

FDA silicone is typically found in products related to food, health, and pharmaceutical industries. This material is free of peroxides, ozone and UV resistant, and has low volatility.

Electrically Conductive Silicones

Electrically conductive silicones are a very versatile material for injection molds. They are in used in the automotive industry, as well as for industrial and military applications for their sturdy nature.

Fiberglass-reinforced Silicones

Fiberglass-reinforced silicones have recently been gaining popularity in injection molded parts due to their high strength and high temperature resistance properties. Fiberglass-reinforced silicones can be found in automobile parts.

Summary

When starting to plan your rubber injection product, it’s important to understand the types of rubber material available and which of them will be the best application for your purpose. Some materials can be more resilient to mechanical stresses, spills, or environmental exposures, while others may be lower in cost while still getting the job done for your purpose.
