Top 10 Pyramidal Foam Manufacturers in China 2025

Introduction to Pyramidal Foam

Pyramidal foam, also known as microwave absorbing foam, is a crucial material in the field of electromagnetic wave absorption. It is characterized by its unique pyramid - shaped structure. This structure effectively enhances the multi - reflection and absorption of electromagnetic waves within the foam, thereby achieving a high absorption rate of electromagnetic waves in a wide frequency range. Pyramidal foam is widely used in various applications such as electromagnetic compatibility (EMC) testing chambers, anechoic chambers for antenna testing, military stealth technology, and scientific research in the field of electromagnetics. The performance of pyramidal foam is mainly evaluated by parameters such as absorption rate, frequency range, and flame retardancy.
