The properties of vulcanized rubber for machinery

Properties of vulcanized rubber: If mainly used for the processing and production of vulcanized rubber, the properties of vulcanized rubber are mainly for customers and practical applications. The properties of vulcanized rubber can be divided into two major categories: mechanical properties and environmental properties. The former is the measurement of rubber under load conditions, mainly including tensile strength, tensile modulus, elongation at break, permanent deformation under tension (all on the tensile machine), hardness, resilience, compression permanent deformation, tearing strength, thickness and strength, etc. The latter is the measurement of the performance changes of rubber in the external environment, including thermal aging performance, ozone resistance performance, flame retardancy, mold resistance performance. Briefly introduce the commonly used test items for vulcanized rubber: 1. Tensile strength. 2. Constant tensile strength. 3. Elongation at break. 4. Permanent deformation. 5. Tearing strength. 6. Hardness. 7. Wear resistance. 8. Adaptability. 9. Anti-aging performance. 10. Cold resistance.
