AT303 ASTM Series Apparent Density Tester is used to measure the apparent density, bulk factor, and where applicable, the pourability of plastic materials such as molding powders. The apparatus consists of a measuring cup and a funnel. These series testers conform to ASTM D1895.

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.

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 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.
