Low Temperature Stress Relaxation Tester – Creep Tester (-50℃~0℃)

Low Temperature Stress Relaxation Tester – Creep Tester (-50℃~0℃)

• Primarily used for Low Temperature Stress Relaxation and Creep Test of vulcanized rubber, thermoplastic rubber, and plastic.
• This Low Temperature model of our Stress Relaxation Tester – Creep Tester product group measures the creep and stress relaxation characteristics of the samples in a temperature range of -50℃ to 0℃.

Low Temperature Stress Relaxation Tester – Creep Tester - Principle

Method 1:

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

Method 2:

At a designated 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: Suitable for industries such as Polymer Industry, 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.

The low-temperature creep stress relaxation tester evaluates the deformation performance of vulcanized rubber under low temperatures and long-term load, which is crucial for engineering applications and product design.
