Rubber Material Testing Equipments Supplier

Rubber Material Testing Equipments

Rubber materials are used extensively in automotive seals, industrial gaskets, hoses, and consumer goods. To ensure consistent performance under mechanical stress, temperature extremes, and chemical exposure, comprehensive testing is essential. Shijiazhuang Zhongshi Testing Machine Co., Ltd. offers a suite of rubber material testing equipments designed to generate reliable data and support quality control across diverse industries.

Core Testing Capabilities

• Tensile Strength and Elongation: Our universal testing frames apply controlled tensile loads to rubber specimens, measuring ultimate tensile strength, yield point, and elongation at break. Grips and fixtures are available to accommodate both standard dog‑bone samples and custom geometries.

• Compression Set: Compression set testers evaluate the permanent deformation of rubber after prolonged compression at elevated temperatures, per ASTM D395. This measurement predicts seal retention performance over time.

• Dynamic Mechanical Analysis (DMA): DMA instruments assess viscoelastic properties by subjecting samples to oscillatory stress and temperature ramps. Storage modulus, loss modulus, and tan delta curves reveal glass transition and damping characteristics critical for vibration-damping applications.

• Ozone and Weathering Resistance: Automated ozone chambers expose rubber strips under controlled strain to defined ozone concentrations. Weathering testers simulate sun, moisture, and temperature cycling to forecast outdoor durability.

• Abrasion and Wear: Taber and DIN abrasion testers quantify material wear through programmable wheel speeds and loads, tracking weight loss or thickness reduction after cycles.

Technical Highlights

• Load Range: 0–10 kN for tensile and compression tests

• Temperature Control: –70 °C to 200 °C for environmental chambers

• Ozone Concentration: Up to 100 ppm with strain adjustment from 5% to 50%

• Data Acquisition: High-speed sampling (up to 10 kHz) with real-time graphical display and customizable report generation

Industry Applications

• Automotive: Validating door seals, engine mounts, and vibration-dampening bushings

• Oil and Gas: Testing high‑pressure sealing elements under combined thermal and chemical stress

• Consumer Goods: Ensuring durability and comfort in footwear soles, sports equipment, and household products

• Aerospace: Assessing elastomeric components for hydraulic system integrity and thermal cycling resilience
