Weight Reduction in Building Components Through POM Material

Background Information

A construction client approached us seeking to reduce the weight of select building components by replacing traditional metal parts with plastic. While our expertise typically focuses on small, precision components, this project involved unusually large parts for construction applications.

Problem Statement

The client initially considered black polypropylene (PP) for the components. However, PP in the required thickness was unavailable. Their requirements included black coloration, a specific gravity below 2, and stable dimensions, all while maintaining cost efficiency. The challenge was to identify a plastic that met these criteria and could perform reliably in indoor building applications.

Solution Implementation

After reviewing suitable options, we recommended black POM (Duracon®). POM offered low water absorption, excellent dimensional stability, and consistent performance under indoor conditions. While its weather resistance is lower than other plastics, the components would not be exposed to outdoor elements, and the material’s inherent strength exceeded the functional requirements. By selecting POM, we provided a solution that met the client’s specifications while avoiding unnecessary overengineering.

Results

The switch to POM allowed the client to replace metal components with plastic, achieving significant weight reduction without compromising functionality. The solution satisfied all performance and dimensional requirements, streamlined production, and maintained project cost efficiency.
