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.

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.

HY4670 Carbon Black Dispersion Tester is a system to determine the carbon black dispersion of polyolefin pipe, fittings and compound material. It is also suitable for pigment dispersion test.

HY4241 Electric Falling Dart Impact Tester is used to determine the impact resistance by free-falling dart method. It can be used for plastic films, sheets and composite films e.g. PE preservative films, wrapping films, PET sheets and other food package and heavy package, aluminum foils and aluminum plastic composite films, paper and paper board etc. It can meet the request both of method A and method B.

HY4011 Profile Sample Cutter is used to make samples of plastic boards, pipes, profiles and other non-metallic materials.

HY3110D Digital Densimeter is used to determine the density of rubber, plastic or other similar material. It can be read directly, no need to weigh and calculate, easy to operate. It is widely applicable for production department and experimental research department.

HY4245 Pipe Chamfering Machine is designed for chamfering small size pipes. It’s an ideal tool for pipe manufacturers, scientific and research institutions.

HY3130 Rebound Resilience Elasticity Tester is used for determining the rebound resilience of rubber with a hardness ranging from 30IRHD to 85IRHD. Resilience elasticity is defined as the ratio of the regained energy to the applied energy. This energy ratio corresponds to the quotient of the resilience height and the pendulum drop height. It fully complies with.

HY4630 Oxygen Index Tester is used to determine the relative flammability of plastics and other materials by measuring the minimum oxygen concentration that will support combustion. The test specimens are burned in a precisely controlled atmosphere of nitrogen and oxygen.

HY4140 Full Notch Creep Tester is used to determine the stress cracking resistance of polyethylene materials in any environment. A test specimen in the form of a square-section bar with coplanar notches in each face at the center, is subjected to a static tensile load in a temperature-controlled environment. The geometry of the specimen is such that plane strain conditions are obtained and brittle failure occurs under appropriate tensile load and temperature conditions. The time for this brittle failure to occur after loading is recorded.

HY4640 Viscosity Tester is used to determine the viscosity of Poly(vinyl chloride) resins in dilute solution using capillary viscometers. This machine conforms to ISO 1628, ISO307, GB/T 3401, GB/T 14190, etc.

HY4150 Environmental Stress-Cracking Tester is used to determine the susceptibility of ethylene plastics to environmental stress-cracking when subjected to specified conditions. In the presence of environments such as soaps, wetting agents, oils, or detergents, ethylene plastic may exhibit mechanical failure by cracking.

HY4320C HDT/Vicat Tester is used to determine the heat distortion temperature (HDT) and Vicat softening point of plastic materials. It is widely suitable for plastic, hard rubber, nylon, electrical insulating materials, long fiber reinforced composite materials, high strength thermosetting lamination materials and other non-metallic materials.
