Chemical, Physical, Mechanical Properties Characterization of Plastics

Testing plays an important role in the life cycle of a polymer, from the raw material to the semi-finished and finished product. Chemical testing of a plastic product is a complex process, it can provide valuable information about the additives used and other substances present in the product. Physical and mechanical testing of plastics can ensure that the material complies with industry specifications that can be applied to plastics used in the aerospace, automotive, consumer, medical and defence industries. Understanding the performance of a material is a key concern to suppliers, manufacturers and product developers in the polymer industry. It can help industry choose appropriate additives.

Typical Test Solutions for Plastics Industry:

Chemical property

• Molecular weight (MW) of polymers, structure, chemistry of fractions, end groups, tacticity, unreacted monomer and oligomers, co-polymer content, blend composition, catalyst residues, contamination analysis, trace chemical analysis and volatile organic compounds testing.

Mechanical property

• Tensile property, bending property, impact property, compression property, tear resistance, shear performance, hardness, fatigue property, creep property, friction, dynamic mechanical properties, compression set static stiffness, dynamic stiffness, Poisson's ratio, Young's modulus, ring stiffness, aging coefficient, etc.

Physical property

• Physical testing including density, air permeability, water absorption, surface properties, optical properties, ash, solid content, viscosity, gel time, glass fiber content, carbon black content, gel content, shrinkage, dispersity, etc.
