Macro Pop

Macro Pops are hollow Spheres (often referred as macrospheres or mini spheres) made of thermoset resins reinforced with various fibres such as carbon fibres, glass etc…

They are manufactured in various sizes ranging from 2mm to 300mm in 3 different grades (S, L, UL) and can withstand pressure up to 800 Bar.

Materials and densities can be tailored to obtain the perfect combination between density and strength to meet the design requirements of a specific application.

Being light weight and high strength, Macro Pops offer additional benefits when using voids in materials simply due to the fact that they occupy up to 80-85% of a volume.
