Selecting the right material is a critical factor in achieving reliable performance, system safety, and long service life. Each material offers different properties such as resistance to temperature, chemicals, oils, mechanical stress, and environmental exposure.
The following guide provides an overview of commonly used rubber and polymer materials to help engineers, designers, and manufacturers select the most suitable material for their applications.
Rubber Material Overview
The table below provides a comparison of common industrial rubber materials, including their temperature ranges, key performance properties, and typical applications.
This overview helps engineers and system designers quickly identify suitable materials for sealing systems, tubing components, and machinery parts operating under different environmental conditions.
High Performance Polymers Material Overview
Advanced Polymer Materials for Industrial Applications
For applications that require high chemical resistance, dimensional stability, or superior material purity, PTI Global Products also provides a wide range of advanced polymer materials.
These materials are widely used in:
Industrial Sealing Systems
Industrial Tubing
Plastic components for machinery
Extrusion and custom polymer profiles
High performance polymers are engineered to perform reliably in demanding environments where exposure to chemicals, temperature variations, and mechanical stress is common.
With their excellent chemical resistance, mechanical strength, dimensional stability, and processability, these materials are ideal for a wide range of industrial manufacturing and equipment applications.
Key Factors in Material Selection
Material Selection Factors
To ensure optimal performance and long service life for sealing systems and tubing applications, the following four engineering factors should always be considered.
1. Temperature Resistance
The operating temperature range of the system must be evaluated to prevent premature material degradation.
Low Temperature: Materials must remain flexible and resist cracking in cold environments.
High Temperature: Materials must maintain shape and elasticity when exposed to heat.
2. Chemical Compatibility
Materials must resist chemical degradation when exposed to:
Oils and fuels
Solvents
Zcids or alkalis
For example:
NBR or FKM are recommended for oil exposure
PTFE or PVDF are suitable for chemical environments
3. Mechanical Properties
Selecting materials with suitable mechanical properties helps extend the life of machinery components.
Important factors include:
Flexibility & Elasticity: The material must deform and recover without cracking.
Compression Set: The material must maintain sealing performance under long-term compression.
Durability & Abrasion Resistance: The material must withstand friction and wear.
4. Environmental Exposure
For outdoor or harsh environments, materials must withstand:
UV radiation
Ozone
Moisture
Weather conditions
Materials such as EPDM are commonly used in outdoor sealing applications due to their excellent environmental resistance.
Example Material Selection for Industrial Applications
Selecting the correct material can significantly extend the service life of seals, tubing, and machine components.
Outdoor Sealing Systems
Recommended material: EPDM
Due to its excellent resistance to UV, ozone, and weather conditions.
Oil Exposure Systems
Recommended material: NBR
Ideal for machinery seals and hydraulic systems exposed to oils.
High Temperature Applications
Recommended material: Silicone Rubber
Suitable for ovens, food processing equipment, and high-temperature machinery.
Chemical Transfer Systems
Recommended material: PTFE or PVDF
Both offer outstanding chemical resistance for aggressive environments.
