Natural rubber is an organic elastomer derived from the sap of rubber trees (Hevea brasiliensis). Known for its flexibility, tensile strength, and abrasion resistance, natural rubber remains a widely used sealing material in applications requiring durability and vibration absorption.
Compared to many synthetic elastomers, natural rubber offers excellent elasticity and tear resistance, making it useful for sealing and cushioning applications where flexibility and mechanical strength are important.
North Coast Seal supports OEMs and industrial manufacturers with natural rubber sealing materials used in:
Natural rubber is often selected for applications requiring repeated flexing, stretching, or vibration resistance.
Typical material characteristics include:
Natural rubber compounds generally operate within a temperature range of approximately:
-58°F to 158°F (dry heat only), with Shore A hardness values typically ranging from 40 to 90.
Because of its resilience and flexibility, natural rubber is commonly used in applications involving movement, cushioning, and wear resistance.
Natural rubber is commonly used in:
Its flexibility and durability make it especially useful in applications involving repeated motion or mechanical stress.
While natural rubber offers strong mechanical properties, it is not ideal for every operating environment.
Natural rubber is generally not recommended for applications involving:
Exposure to ozone, sunlight, oils, or excessive heat can lead to cracking, degradation, hardening, or premature seal failure.
No single elastomer is ideal for every sealing environment. Engineers often evaluate:
before selecting a sealing material.
Natural rubber remains a strong option for applications prioritizing flexibility, tear resistance, and vibration control in non-oil environments.
North Coast Seal supports OEMs with material selection guidance and custom sealing solutions for industrial applications.
"*" indicates required fields
Natural rubber is commonly used for flexible seals, gaskets, vibration-dampening components, and industrial applications requiring strong elasticity and abrasion resistance.
No. Natural rubber is generally not recommended for applications involving petroleum oils, fuels, or hydraulic fluids.
Natural rubber offers strong tensile strength, excellent flexibility, tear resistance, and abrasion resistance compared to many elastomers.
Natural rubber has limited resistance to ozone, UV exposure, oils, fuels, and elevated temperatures.
Natural rubber provides excellent flexibility and mechanical strength, while EPDM generally performs better in outdoor, ozone, and weather-exposed environments.
It depends on the application. Natural rubber often offers better elasticity and abrasion resistance, while neoprene provides broader environmental and oil resistance.
