Lab Testing, Certification & Compliance

Ensuring TPE meets all critical requirements. 

As an ISO 9001: 2015 certified company, material performance isn’t just promised — it’s proven. Our in-house testing lab and external certification partnerships ensure that every compound we manufacture meets the mechanical, chemical, and regulatory benchmarks your industry demands.

From automotive durability to medical-grade biocompatibility, we verify that our thermoplastic elastomers (TPEs) meet or exceed performance requirements — before they reach your production line.

In-House Lab Capabilities

We operate a fully equipped laboratory for TPE compound testing and development. This allows us to provide real-time quality control, rapid prototyping, and material validation. Core lab services include:

  • Hardness (Shore A & D) – Durometer testing for consistent softness and flexibility.

  • Tensile Testing – Validation of strength and stretch performance.

  • Compression Set – Measures material recovery after deformation using a fixed weight at a specified temperature.

  • Melt Flow Index (MFI) – Gives an indication of a polymer's flow characteristics at a single point of shear

  • Rheology - Performs viscosity measurements under applied forces with varying amounts of shear. 

  • Density – Ensures uniform weight of the material across batches.

  • Color Matching & Visual QA – Custom coloration and surface inspection.

  • Heat Aging – Perform a variety of testing using heat aged test specimens

  • Adhesion Testing – For materials intended to over mold onto a substrate 
     

Need a custom formulation validated to specific parameters? Our lab can simulate application conditions and run comparative tests on prototype parts.
