Lightweighting substrates can be more flexible but also weaker, so some products may need reinforcement to increase strength. However, the reinforcing materials must be light-weight enough to provide a net reduction in product weight. 3M Brand Adhesion Technology can be used to achieve this in a variety of applications.

Heat and flame resistance are critical considerations in designing products . Some applications may require overall heat resistance while others need one-time protection from a flame event at the end of product life. When lightweighting, if a new substrate is susceptible to heat or flame, 3M Brand Foil Tapes may provide the necessary protection.

A change to lightweighting substrates, especially from metal to plastic, can significantly change the appearance of products and create the perception of reduced quality. However, this can be addressed by adding veneers to new substrates or products to enhance their aesthetics and consumer appeal. Decorative film solutions from 3M can be used on products to make plastic surfaces more visually appealing.
