TST-300
TST-300 Congo Red Thermal Stability Tester is used to determine the thermal stability of PVC compounds for insulating and sheathing materials of electric cables. Test principle: Place about (50±5)mg sample into a specified glass tube. The glass tube is placed into an oil bath at a temperature of (200±0.5)℃. A Congo red paper or common pH paper is inserted into the glass tube; its other end is folded and hung on the top wall of the glass tube. Record the time during which the Congo red paper changes from red to blue (the common pH paper changes from pH5 to pH3). The time of color change is an expression of the thermal stability. This instrument complies with the following international and industry standards. IEC: IEC 811. GB/T: GB/T 8815, GB/T 2951.7. Technical Specification Model: TST-3000 Temperature range: RT~250℃ Temperature resolution: 0.1℃ Timer range: 0~99.99s Chamber: capacity 3000ml Glass: tube size Length: 1100mm External diameter: 5mm Inner diameter: 4mm Test paper: Congo red paper or pH paper Heating oil required: 2# lubricating oil or insulating oil Heater power: 1.25kW Power supply: AC220V 50Hz Dimensions: 420mm×200mm×250mm (L×W×H)

Dial Type Plastic Charpy Impact Tester
HY4251A Charpy Impact Tester is used to determine the impact toughness of non-metallic materials such as rigid plastics, fiber-reinforced composite materials, nylon, glass, ceramics, cast stone, asbestos boards, electrical insulating materials, etc. It is suitable for notched and unnotched specimens.
HY4900 Torque Rheometer
HY4900 Torque Rheometer is a measuring system for studying the flow, plasticizing, heat and shear stability of polymers. This system consists of a platform and some function units, such as the mixer and extruder. The platform connected with a function unit can measure flow and compounding behaviors, critical processing parameters of temperature, pressure, torque and viscosity of polymers in the laboratory—requiring only small sample volume. This instrument, which is designed as an excellent system with high measuring precision, handling flexibility and testing reproducibility, has been widely applied in scientific research, quality control and process experiment.
HY4660 Carbon Black Content Tester
HY4660 Carbon Black Content Tester is used to determine the carbon black content of polyolefin compositions. The principle is: pyrolysis of a specified quantity of mixture at a specified temperature in a stream of nitrogen for a certain time and calcination at a specified temperature; Calculation of the carbon black content from the difference in mass before and after calcination and pyrolysis.
