What Kinds of Cases Can a Polymer expert witness handle


A polymer is primarily combination of several smaller repeating subunits that make up a large molecule. This large molecule or macromolecule is known as a polymer. Polymers exist almost everywhere and in many different forms. They can be found around us in the form of plastics, for example polystyrene and they can also be found inside us which are known as biopolymers, for example DNA. Talking about synthetic polymers, it’s use has escalated since the day it was invented. Plastic is being used in everything ranging from a hard plastic bottle to the soft fabrics of nylon. For the synthesis of a good plastic product, a polymer expert witness is needed who can handle various types of cases explained below.

Product Liability

Product liability is a case in which the product did not fulfil its purpose. This means that the product is defective. A situation regarding this case includes the personal injury in which the plastic fails in its use. When a plastic fails it may melt out when it experiences high temperature and the hot liquid it contained may get spilled on a person causing a serious injury. This incident can be taken on a higher notice as such a bad experience might urge the user to start a case against the company or even the one who supplied the product.

The plastics that are less resistant to heat with low temperature tolerance are capable to fail in its use. So when situation turns out to be like the one explained above, the polymer expert witness handles the case by finding out the cause behind the incident whether the user did not handle the product with care or the product supplier did not use the acceptable standard of material in the making of product.

Patent Infringement

Such cases can be very challenging. Any random expert can not be suitable for such cases. As the discipline of plastic is very extensive and for cases like these the expert with a proper knowledge of chemistry would be appropriate. For instance, there is one type of polymer known as thermoset which is initially a liquid and then it experiences a chemical reaction while processing. For relevant cases the polymer expert must have proper knowledge and recognition of material properties. Whereas, another type of polymer known as thermoplastic, is a solid at room temperature but when undergoes a molding process it can be melted to change it into assorted shapes. For this, the polymer expert witness must have deep information and understanding about molding and physical property measurements.

These are the kinds of cases a good polymer expert witness can handle. Right expert witnesses can be identified by their education and experience. Moreover, you can always ask them questions about their experience with the plastics and ask about their skills as in, what is the type of case they’re more experienced in. All this analysis will help you choose the best polymer expert witness appropriate for your type of case.
