Stress Relaxation Tester – Creep Tester (0°C to 150°C)

Stress Relaxation Tester – Creep Tester (0°C to 150°C)

• Primarily, used for Stress Relaxation Test and Creep Test of vulcanized rubber, thermoplastic rubber, and plastic.
• This advanced system analyzes the creep and stress relaxation characteristics of the samples within a temperature range of 0°C to 150°C.

High Temperature Stress Relaxation Tester – Creep Tester - Principle

Method 1:

The sample is pre-compressed to a specified displacement (adjustable from 0 to 30mm) at a set temperature. Subsequently, it undergoes continuous compression at a fixed displacement for a specific duration, while the force/time change curve is detected and fully recorded.

Method 2:

At a set temperature, the sample is pre-compressed with a specified force (adjustable from 0 to 10kN). It is then continuously compressed for a defined duration under a constant force, while the displacement/time change curve is monitored and fully recorded.

• Used in Many Industries: Ideal for industries such as Polymer, Materials Science, Civil Engineering, Aerospace, Academic Research, and General Industrial Manufacturing.
• Stress Relaxation: Occurs when a constant strain is applied to rubber, resulting in a gradual decrease in the force needed to maintain the strain over time.
• Creep: Involves a constant stress applied to rubber, causing the deformation needed to sustain the stress to gradually increase over time.
• Static Creep: This is the gradual increase in displacement of rubber elastic elements over time under a constant static load.
• Static Stress Relaxation: The force exerted by rubber elastic elements gradually decreases over time while maintaining constant deformation.
• Compressive Stress Relaxation: After subjecting the specimen to constant compression deformation under a constant pressure, the compression force gradually decreases over time, expressed as a percentage of the initial force.
• Tensile Stress Relaxation: Following constant tensile deformation under constant pressure, the tensile force gradually decreases over time, expressed as a percentage of the initial force.
• Meets Industry Standards and Regulations: Ensures compliance with relevant industry standards and regulations, thereby minimizing risks and enhancing product marketability.

The High-Temperature Stress Relaxation Tester – Creep Tester evaluates the deformation characteristics of vulcanized rubber under elevated temperatures and prolonged loading, crucial for engineering applications and product design.
