Accelerated Creep Testing of Polymers with Time-Temperature Superposition

A medical device designer wanted to forecast the creep performance of a plastic part for at least two years. Veryst tested the material using time-temperature superposition to characterize the material’s long-term performance quickly and efficiently to determine if the design performs adequately after two years.

Additively Manufactured Lattices

Additive manufacturing (AM) enables the production of complex lattice structures that cannot feasibly or economically be manufactured any other way. However, there are complicating factors that engineers are likely to confront when designing fine AM lattice structures: geometric inaccuracy and anisotropic material properties.

Adhesive Cure Troubleshooting with Differential Scanning Calorimetry (DSC)

An adhesive joint was failing in the field. Veryst used DSC to investigate and determined the root cause to be improper curing of the adhesive.

Adhesively Joining Difficult Materials with Corona Plasma Treatment

Joining polyolefins such as polyethylene and polypropylene with adhesives can be challenging. Polyolefins have low surface energy, which creates weak bonds between the polyolefin material and the adhesive. Veryst used corona discharge plasma treatment to improve the bond strength and create a more robust joint.

Anisotropy of 3D-Printed Polymers

Many additively manufactured polymers exhibit anisotropic mechanical properties which must be accounted for by engineers designing with these materials. This case study illustrates the importance of testing additively manufactured polymers at many orientations to identify the range of isotropic behavior as well as the optimal build orientation.
