Recent advances in the research of plastic test instruments

 1.In recent years, plastic material detection has become more and more complicated. Compared with the past, the analysis and evaluation, elastomer, polymer composite materials and thin film performance testing instrument and equipment of higher accuracy, and the results more consistent, better repeatability. In many cases, the digitized reduce the price of the test equipment, and accepted by many processing enterprises, and is used for internal testing and advanced quality control. Plastic test is mainly used for the development of new materials technology assessment shows that material use, determine whether the products can satisfy the different conditions of the final with use requirements, verify the design concepts, to ensure product quality and safety.

2.Overview of plastic performance

Plastic with traditional materials such as metal, glass, pottery and porcelain has many different, its outstanding characteristic is qualitative light, to heat and electricity has good insulation, the strength, stiffness, although lower than metal, but than strength, stiffness is likely to be close to or more than metal. The flexibility of plastic is significantly better than that of glass and ceramics, and the toughness of different plastics may be lower than, near or above metal. The response of the external loading charge, metal, glass, ceramics is elastic, plastic is viscoelastic. The mechanical properties of metal, glass and ceramic are very sensitive to the influence of plastic mechanical properties. The effect of humidity on metal, glass and ceramic mechanical properties has no effect on the mechanical properties of plastics. The effect of humidity on metal, glass and ceramic mechanical properties has no effect on the mechanical properties of plastics

3.The need for plastic testing:

（1）Evaluate the performance behavior of the material to determine its suitability for the applied application

（2）To evaluate whether the material meets the requirements for safety regulations;

（3）For quality control purposes, evaluate the quality and consistency of each batch of products;

（4）Special evaluation of materials for user support
