Medical Device Testing, Polyurethane Material-Image

APL, Inc uses the science of rheology for Medical Device Testing and Polyurethane material with the purpose of accurately modeling the melt flow of the materials being tested. Compliance is crucial to how your product will work specifically. This ensures that your final product will meet your specified FDA compliance requirements.


  • The study of deformation and flow. In other words, the study of the flow of materials that behave in an interesting or unusual manner. Examples of normal, familiar flow of materials would be, oil, water, air. Sir Isaac Newton, studied these materials and created laws of physics that explain why they behave and flow in a predictable way.

  • Other materials behave in interesting or unusual ways. Examples of paint, foams, melt plastics, and other fluids behave in a different variety of ways. These materials do not fall into the Newtonian flow laws. The science of studying these types of unusual materials is called rheology. The scientists who study the mathematical relationships that describe the behavior of these unusual fluids are called Rheologists.

Associated Polymer Labs, Inc. incorporates this science of rheology for the purpose of accurately defining the melt flow of the materials being tested. This gives a more accurate, definable way to follow behavior of newly discovered and complex polymers and synthetic rubbers. When assisting a client, this type of testing would be crucial to define the temperature of manufacturing a certain polymer and cooling temperature and time to keep the integrity of the plastic/resins that is being used.

  • If a material is being used in a medical application, certain specifications to keep the product certified are required. Manufacturing processes are crucial to keeping the integrity of the product.

  • Associated Polymer Labs, Inc. uses RHEOLOGY and product knowledge to help clients keep within these guidelines, to make a superior product, with minimum waste, and low downtime. This can save the company time, money, and legal obligations from making a faulty product.


  • A medical device company inquired why they were having problems injection molding their catheter tips. They were having many problems with bubbles, voids and overall performance problems.

  • APL tested and evaluated these catheter tips. APL was able to pinpoint the cause of the problems. The company then had the tools to locate the specific changes that needed to be made with the compounder and the manufacturing department. APL was able to identify the root cause of the problem and make corrections before product launch. Associated Polymer Labs, Inc. was able to save this medical company millions of dollars in failed product, and manufacturing time. APL now tests and certifies every lot from their compounder. The process was streamlined which now produces great income for this company.
