Perance  composition analysis of polymer materials

Perance composition analysis of polymer materials

Macromolecular materials, also known as polymers, usually include plastics, rubber, chemical fibers, coatings, adhesives, etc. It is wiy used in electronic appliances, toys, automobiles, construction, textile industry other fields. Due to the characteristics of polymer materials, in order to ensure the durability high quality of products, the detection of the composition of materials has become a common requirement in the production, research development, quality control processes. Infrared spectrometer is a common testing instrument for determining the composition of polymer materials.

High polymer material perance test

In order to obtain better application of polymer materials, it is necessary to underst the composition, content certain physical chemical properties of polymer materials, it is necessary to conduct component analysis perance testing of polymer materials.

Rheological properties: melt mass/volume flow rate, mold shrinkage rate


Mechanical properties: tensile elastic modulus, tensile stress, tensile strain, tensile creep perance, bending modulus, bending strength, simply supported beam/cantilever beam impact strength, Shao Hardness, ball indentation hardness, Rockwell hardness, compressive strength
