Material analysis

Material analysis

Polymer or plastic materials are increasingly used for example to replace metallic or ceramic parts. They have complicated nature – but we understand them. Let us help you to choose the right materials for your product, to understand more about the polymers you are using and to solve polymer-related problems you may be facing.

Selecting the right material

With right selection of polymer material in your product you can

*Improve reliability
*Lower costs
*Develop new functionalities
*Improve process control

Material manufacturers often give limited data for their materials. This lack of data may restrict the reliable and effective use of materials and lead to failures and quality problems. With our help you really understand how materials behave in your application.

We can help you if you

*Are considering new materials, but are not sure of their properties and suitability
*Want to be sure that your materials meet your specifications
*Want to make sure your materials meet your reliability requirements
*Have problems with your current materials such as unknown failures from field
*Are looking for new environmentally friendly and sustainable materials
*Are considering the use of polymers and composites to replace metallic and ceramic parts
*Are unsure or want to optimize the processing conditions of your materials

Our Know your materials -service helps you with material selections!

Long-term reliability of polymers

 

What if the plastic used in your casing becomes fragile and breaks only after a short use?

What if humidity significantly changes the properties of your plastic material?

 

 

The properties of plastics and polymers change in different conditions. Especially after a long-term exposure, this change can be permanent and is a very common reason for unexpected fatal failures in products. To understand how your product is doing in the long-run, we combine reliability testing with material characterization methods. During years, we have also built a big picture, how commonly used polymer materials behave, what are the critical factors and how the material should be tested and analysed.

We help you to

*Considers the critical factors in your application and materials
*Get tools and data to identify critical parameters and improve the reliability of your product
*Find the best methods for testing and analysis – optimal ones depend on the application and material and its chemistry
*Determine whether the material is suitable for your use in the long-run

Our Know your materials, long-term stability -service helps you with stability issues!

Material characterization methods

There is an endless number of different material characterization techniques. Suitable methods depend on the material and studied parameter. We can for example analyse the following parameters and use following techniques:

Thermal properties such as

*Coefficient of thermal expansion, CTE
*Glass transition temperature, Tg
*Crystallinity and melting temperature
*Softening point of films and other materials
*Curing degree and temperature for adhesives and other thermosets
*Oxidation temperature and time

Mechanical properties

*Tensile testing
*Three-point bending
*Pull and peel testing
*Shear testing for adhesion
*Young’s modulus and flexural modulus for films and small components
