Improving Insulation Performance with Microspheres

Microspheres are spherical particles ranging from 1-1000 µm in diameter. These materials can be produced with varying densities and structural properties and thus accommodate a vast range of applications. Microspheres are either solid or hollow in nature, each with its own unique set of characteristics. Hollow microspheres are the lowest in density and an ideal additive for decreasing material weight and/or improving insulative properties. Solid microsphere usage is highly influenced by the material type and size chosen, but applications include additive manufacturing, biomedical and more. Some examples of common microsphere materials include polystyrene, polyethylene, and glass.

Due to the wide range of microspheres, understanding their individual properties are important to ensuring they meet the requirements for the specific application. Thermal conductivity is a key metric when aiming to assess thermal performance and highly influenced by the type of microsphere in question. Using Trident’s multi-sensor approach, regardless of sample format or test parameters of interest, there is a configuration available for thermal characterization.

In today’s webinar we will discuss the importance of thermal characterization on this class of material, focusing on thermal conductivity analysis via Trident. The influence of particle size and material type will be highlighted as key parameters of interest. Specific case highlights will also be covered demonstrating the importance of thermal analysis for applications involving microspheres for packaging, insulation and chemical processes.

This webinar will air on January 28, 2021 @ 2:00PM GMT-4.
