Applications of Solid Rubber

We can manufacture durable synthetic and natural solid rubber products in a range of thicknesses, operating temperatures, and shapes. The solid rubber gasket material used can also affect its characteristics and recommended applications. Here are some example uses for solid rubber:

Seals: Solid rubber creates a firm seal between two materials, keeping out moisture, air, or dust from interior or exterior environments. The durability of solid rubber makes it a useful choice when one or both components are moving parts.
Trims and Extrusions: Edging materials made of solid rubber act as a seal while also protecting equipment from direct impacts and abrasions.
Gaskets: Two static components can also enjoy a leak-free connection using solid rubber.
Shock Absorbers: Direct impact can cause excessive shock in a piece of equipment, so solid rubber is often employed to reduce the damage of shock and vibration.

Solid rubber, while capable of withstanding extreme shock and vibration, doesn’t absorb them as efficiently as foam rubber. Solid rubber lacks the air cushioning effect of foam rubber.

Environments That Use Solid Rubber

Many connections of two components that shouldn’t leak can use solid rubber gaskets. These versatile gaskets are used to connect water lines, exhaust pipes, and air vents. Applications can use them to prevent air or liquids from escaping around the following items:

Industrial Tanks
Engine Blocks
Exterior Doors
Frames
Fittings

These are just a few examples of the many areas where solid rubber used for gaskets can provide a mechanical seal. While there are some heat-related restrictions to consider, solid rubber is generally versatile enough to be used in most environments.

Common Solid Rubber Materials

Many rubber products are offered in standard commercial grades as well as high-grade. Generally, high-grade materials will have a higher percentage of the actual product (ie Nitrile) and may have a higher tensile strength and/or operating temperature range.

A list of the most commonly used rubbers and their characteristics are listed below.
