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.

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 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.
