Natural Rubber Seals Frequently Asked Questions
What is the temperature range for natural rubber seals?
Natural rubber seals perform optimally in temperatures ranging from -40°F to 180°F, with excellent cold resilience properties.
Are natural rubber seals chemical resistant?
While natural rubber offers good resistance to water absorption and oxidation, it has limited resistance to oils, ozone, and chlorinated hydrocarbons. Our engineering team can help select the optimal material grade for your specific chemical environment.
What makes CTG’s natural rubber seals superior?
Our natural rubber compounds feature high tensile strength (>3,000 PSI), excellent tear resistance, and superior compression set properties. Combined with our precision manufacturing processes, these characteristics ensure reliable, long-lasting sealing solutions.
Can CTG provide custom natural rubber seal designs?
Yes, our engineering team specializes in custom seal design and manufacturing. We offer comprehensive technical support from material selection through production, including emergency manufacturing services when needed.
