Testing Services

Physical Testing

Our Physical Testing services assess the mechanical properties of materials to ensure they meet industry standards. We evaluate factors such as strength, flexibility, and durability, providing valuable insights that help enhance product performance and reliability.

Tear Strength

Tear strength testing is essential for evaluating the resistance of vulcanized rubber and thermoplastic elastomers to mechanical failure caused by cuts, defects, or stress concentrations. At Cornerstone Materials Group (CMG), we offer precise ASTM D624 testing to help manufacturers ensure product durability and performance in real-world conditions.

Rheology

Rheological testing is essential for understanding how rubber compounds behave during processing and in their final applications. At Cornerstone Materials Group (CMG), we provide expert MDR and ODR testing services to help optimize formulations, enhance processes, and ensure consistent product quality.

Mooney Viscosity

Mooney viscosity testing is essential for assessing the flow characteristics of unvulcanized rubber materials. At Cornerstone Materials Group (CMG), we offer precise Mooney viscosity measurements to support your material development and quality control processes.

Durometer Hardness

Durometer hardness testing is essential for evaluating a material’s resistance to localized deformation, offering crucial insights into material performance. At Cornerstone Materials Group (CMG), we provide precise durometer testing services to assess hardness for a variety of materials across different industries.

Compression

Understanding how rubber performs under compression is critical for ensuring its reliability in demanding applications. At Sigma Testing Services (CMG), we specialize in compression set and stress relaxation testing, delivering comprehensive insights into the durability and functionality of your materials.

Adhesion

At Cornerstone Materials Group (CMG), we provide precise and reliable adhesion testing to evaluate the strength and durability of bonds between rubber, metals, fabrics, and other materials. Whether you’re assessing rubber-to-fabric, rubber-to-rubber, or rubber-to-metal adhesion, our services ensure that your product performs optimally and remains durable under stress.

Tensile

Tensile testing is a fundamental process for evaluating the mechanical properties of rubber and polymer materials under tension. At CMG, we specialize in providing precise tensile testing services tailored to your material performance needs.
