Equipment: Device for mechanical tests Instron 3365

A device for mechanical tests Instron 3365 with a force cell of 500N, used for testing the materials and products made by elastomers. The instrument for mechanical tests is equipped with a high precision video extensometer which allows the deformation measurements with a high accuracy without being in contact with the sample. Furthermore, the device has a climatic chamber which permits the sample testing in a temperature range of -100oC and -350oC. The materials can be exposed to different tests as: traction, traction in cyclic regime or compression. By making the traction and/or compression tests it is possible to determine the highest stretch, stretching stress, Young modulus, residual strain, impact bend strength, yield stress etc.

Equipment: The HAAKE Rheo Win Viscotester VT 7 L plus viscometer

The HAAKE Rheo Win Viscotester VT 7 L plus viscometer is a classic rotational viscometer used for rapid dynamic determination of the viscosity of materials, including polymers, as such or in solutions with various solvents, and the viscosities of reaction systems. Measurements with this device are made in accordance with ISO 2555 standards and the equivalent ASTM D2930 standard. The device is intended for use as a stationary device. The principle of operation is based on immersing the cylinder or working disc in the tested substance and measuring the force required to overcome the resistance of viscosity to rotation or flow and the result is a direct reading of the viscosity value in mPa×s. Operating conditions: - ambient temperature: 10 - 40 °C; - sample temperature: -15 .... + 120 °C. Reproducibility of measured values: +/- 0.2% of scale. Viscosity range: 3 - 6000000 mPa×s.

Equipment: Transmission electron microscope HITACHI - HT7700
