9 Tips for choice seals rubber material?

What are the important factors to be considered when choosing the right sealing material for application?

Preferential Price and Qualified Color

Availability of seals

All influencing factors in the sealing system: e.g. temperature range, fluid and pressure

These are all important factors to consider in your sealing system.  If all the factors are known, it will be easy to choose the appropriate materials.

However, the precondition is that the material must be durable.  Therefore, the first thing to consider is the technical performance.  Let’s start with performance factors.

The service life and cost of the system are important factors to be considered.  All factors will affect your application performance.  It is very important to consider the design factors according to the application.  This includes the materials used, hardware shape and production process.  At the same time, there are environmental factors to be considered, including pressure, temperature, time, assembly and medium.

Elastomer

Elastomers are popular because of their good elasticity.  The elasticity of other materials cannot reach the same level.

Elastomer reuse is difficult and expensive.  Other materials such as polyurethane and thermoplastic materials have much higher pressure bearing capacity than elastomers.

Rubber materials can be used in a variety of different applications.

Important mechanical properties include

● elastic
● hardness
● Tensile strength

Other important features include

● compression set
● heat resistance
● low temperature flexibility
● Chemical compatibility
● Aging resistance
● Abrasion resistance

The most important characteristic is the elasticity of rubber materials.  Let’s learn more about this.

Elasticity is the result of vulcanization.  Elastomeric materials, such as vulcanized rubber, will return to their original shape if deformed.

Inelastic materials, such as unvulcanized rubber, cannot return to their original state if deformed.  Vulcanization is the process of converting rubber into elastomer material.

The selection of elastomer is mainly based on:

● operating temperature range
● Liquid and gas resistance
● Weathering resistance, ozone and ultraviolet
