Dynamic Mechanical Analyzer

 

DMA is a measuring instrument which is used to determine the dynamic characteristics of materials. It applies a dynamic oscillating force to a sample and analyze the material's response to that cyclic force. Basically, DMA determines changes in sample properties resulting from changes in five experimental variables: temperature, time, frequency, force, and strain.

 

 

This instrument can be used to characterize mechanical and/or thermal properties of a great numbers of materials including Polymers, Elastomers, Composites, Metals and metallic alloys, Ceramics, glass, Adhesives, Bitumen (solid and pasty), Paint and varnish (gels or films), Cosmetics (gels, spray), Oils, Biomaterials, Leather, skin hair.
