Testing Capabilities

McClarin's mechanical testing and molecular testing presents valuable information on materials that can effectively remove trial and error (within parameter) from our research development efforts. From an experimental standpoint, mechanical testing also allows us to effectively bring to market new products, as well as ensure a certain level of product performance and consistency as desired by our customers. McClarin's laboratory testing capabilities provide the opportunity to create a more comprehensive material property database, thus enabling us to analyze the behavior and character of a material scientifically. The goal of our laboratory testing of plastic materials is to determine what's best for the customer in a specific application.

The material testing done at McClarin is made up of multiple tests (see below) that comply with the American Society for Testing and Materials (ASTM) which is the foremost testing standards organization. ASTM provides companies like McClarin a universal standard of goals when testing a material.

Test Type What is tested Why it's important
Flexural Test Mechanical Testing The ability of a material to withstand the bending force when applied at a 90 degree angle Determines the overall strength of a material upon impact
Tensile Test Mechanical Testing The ability of a material to withstand forces that tend to pull apart Determines the strength of a material during stretching
Impact Test Mechanical Testing The ability of the material to withstand impact Determines impact data for collision
Compression Testing Mechanical Testing The ability of a material to withstand crushing forces Determines how the material's properties behave as it is squeezed
Flow Analysis Molecular Testing The ability to identify how thermoplastic molecules move in a molten state Determines how a material's molecular make-up reacts when traveling from solid to molten back to solid form.


Depending on the client's application, we may use one or combinations of all to reach a sound conclusion regarding a material's strength, and provide a solid recommendation based on actual data.

McClarin believes it is important that guidelines sent to us from a material's supplier are verified. This service gives you, our customer, an increased level of confidence that the materials selected for your product application will produce consistent results today as well as many years from now.

At McClarin Plastics, we're thorough and particular about our product offerings. Our testing laboratories present great quality control measures as well as verification of material consistency. We believe this service to you is our way of enhancing quality, performance and our relationship with you, our customer.
