Rubber Testing Equipments for Ensuring Product Reliability

Rubber Testing Equipments for Ensuring Product Reliability

Rubber products—from seals and gaskets to tires and hoses—require rigorous testing to guarantee their performance under stress, temperature extremes, and abrasive environments. Shijiazhuang Zhongshi Testing Machine Co., Ltd. supplies a comprehensive range of rubber testing equipments tailored to industry standards and research needs.

Core Testing Instruments

• Compression Set Testers: Measure the permanent deformation of rubber samples after prolonged compression at elevated temperatures, following ASTM D395 procedures.

• Tensile and Tear Testers: Determine tensile strength, elongation at break, and tear resistance, essential for dynamic rubber components.

• Ozone Resistance Chambers: Expose rubber specimens to controlled ozone concentrations and tensile strain to assess crack initiation and growth rates.

• Aging Ovens: Simulate long-term thermal and oxidative aging, providing insights into changes in hardness, tensile properties, and compression set over time.

• Abrasion Testers: Taber or DIN abrasion methods quantify wear resistance for applications such as conveyor belts and footwear soles.

Technical Highlights

• Compression Load Range: 0–10 kN, temperature control up to 150 °C

• Tear Test Geometry: Multiple configurations (angle, crescent, trouser) with force resolution of 0.1 N

• Ozone Chamber Conditions: Ozone concentration up to 50 ppm, temperature 25 °C–40 °C, adjustable strain 10%–50%

• Abrasion Cycles: Programmable wheel speeds, load weights, and cycle counts with automated wear-depth measurement

Application Spectrum

• Automotive Sealing: Verifying that engine gaskets, door seals, and window profiles maintain elasticity and resilience under temperature cycles.

• Industrial Hoses: Ensuring rubber hoses for hydraulic and pneumatic systems resist fatigue, ozone, and pressure fluctuations.

• Consumer Goods: Testing rubber soles, elastic bands, and wearable components for comfort and durability.

• Sports Equipment: Assessing shock-absorbing properties in mats, protective gear, and exercise bands.
