Physical and Mechanical Testing of Polymers

Physical and mechanical testing of polymers ensure polymeric materials meet application performance requirements

Physical and mechanical testing of polymers ensure polymeric materials meet application performance requirements

The physical testing of polymers is a vital part of the product development and production process. Mechanical, thermal, optical, rheological behaviour and climate testing allow the developers to understand their product better, and introduce stronger quality control. These methods are required throughout the research and development process where clear knowledge about the product’s quality and performance, when applied to its intended end use, is a key part of the research process.

Potential Problems

Physical and mechanical testing of polymers ensures that the material complies with industry specifications. This applies to the aerospace, automotive, consumer, medical and defence industries, amongst others. Safety, quality and performance are key concerns, so design and in-service performance must be explored to address potential problems.

With the vast array of product types and additives available, understanding the capabilities and limitations of a material is a key concern to suppliers, manufacturers and product developers on every level of the polymer industry.

Providing solutions
Raw material suppliers and manufacturers can access a multitude of testing methods to determine the properties of their products. Knowing which technique to use in order to obtain the most effective data requires specialist insight, knowledge and experience. When a material or additive does not meet the user’s specifications, expert interpretation and advice is required.

As a one-source solution provider, the breadth of Intertek’s physical and mechanical testing capabilities are vast and includes ASTM, ISO, BS or DIN standards using industry specific methods. Intertek experts can develop customer specific protocols and methods as required.  Our ISO 17025 compliant laboratory services support large research and design projects, quality control, research and development, problem-solving together with failure analysis for advanced materials and products.
