Goodtechwill Testing Machines (Qingdao) Co., Ltd products

This tester is used to determine the plasticity and recovery of unvulcanized rubber, uncompounded rubber, compounded rubber reclaim rubber. The specimen is heated to a specified temperature through a prescribed time and then subjected to stipulated compressive force between two parallel plates via a certain time period to assess its recovery height.

MV-3000-VS is an upgraded model of traditional Mooney viscometer. Adopting a new microprocessor and LCD touch screen with built-in automatic balance and calibration device, it can automatically calibrate by pressing the button. With an accurate specimen temperature control system and high torque measuring precision, this machine is highly sensitive to changes in rubber materials, and has a better repeatability and reproducibility.

M-3000-ADS, with rotorless sealed biconical die system, is a newly designed automatic moving die rheometer. The use of automation in M-3000-ADS helps the end-user to reduce more human involvements. Up to 9 specimens can be carried by the autoloader. Test specimens can be loaded, tested and unloaded in sequence automatically.

MD-3000-AS, with rotorless sealed biconical die system, is a newly designed automatic moving die rheometer. The use of automation in MD-3000-AS helps the end-user to reduce more human involvements. Up to 130 specimens can be carried by the autoloader. Test specimens can be loaded, tested and unloaded in sequence automatically. As a flexible and powerful rheometer, MD-3000-AS offers optional variable temperature analysis and allows the end-user to adjust the oscillation amplitude between ±0.2° and ±3°. This rheometer is well suited for research and development.

Vulcanization is the process that modifies the polymer by forming crosslink between individual polymer chains. This is one of the most important processes in manufacturing which improves the physical proprieties to the final rubber product. The rheometer can simultaneously determine the viscosity, elasticity, hysteresis loss and curing rate during the vulcanization process of the rubber compound. Important vulcanization characteristics such as torque, cure rate index and curing time can be measured.

M-2000-F Rheometer , in addition to used for the determination of rubber vulcanization and viscosity, but also provides a detection of foam rubber and foam process. The curves and data provided by this machine are the most important basis of improving products, mass production conditions and developing new  batching.

PPA-6000 is an up-to-date, cutting-edge and more economic rubber processing analyzer, which is used for processing polymers and master batch, as well as analyzing and controlling rubber compound. This apparatus, in addition to MDR and VTA, has 3 built-in combined test solutions for being used by rubber researchers.
