Plastics

Characterization of polymers’ properties is critical in the development and manufacturing processes of materials, as well as the quality control, and ultimately, in determining the functionality of a finished product.Sansi Test partners with many plastic manufacturers and optimize their testing programs.

Trends in plastics

High performance polymers

High performance polymers can be used in a broader range of applications because of their superior thermal stability and chemical resistance. This allows for plastic components to be used in aerospace, medical, defense, and other industrial applications where the conditions can be extreme which previously would have discouraged the use of plastics. This is achieved using stabilizers and adding reinforcing materials like glass or carbon fibers. These materials are often stronger and stiffer than traditional plastics and will have higher UTS and modulus values. Environmental chambers are used often during mechanical testing to replicate extremely high or low temperature applications.

Going Green

Many consumer product companies have made pledges to reduce the amount of non-recyclable plastics in their products. Along the same lines, many companies have also pledged to use chemically recycled plastics in their products. Either way, there is a push to choose more sustainable options when using plastics, especially in single use items like packaging.

Another way to benefit from the upsides of plastics while choosing sustainable options is to utilize bioplastics. Bioplastics aren’t made of fossil fuels like other plastics, but are derived from plants like corn, potatoes, or sugarcane. Some are biodegradable and compostable.

Creating more sustainable options is a trend for the plastics industry. Mechanical testing is needed anytime a product changes its material type or manufacturing process to ensure the end-use application isn’t negatively impacted.
