Our selection of fillers and modifiers for the composites market has quickly grown over the past few years. We have worked alongside major resin producers to demonstrate the performance and cost benefits of our products for producers of FRP, ceramic-matrix and metal-matrix composite materials.


Quadra offers an extensive range of materials as fillers and performance additives for various types of composites. We work with producers of tub & shower stalls, tanks, architectural panels, cast composites, ceramics, refractories and many other related materials.

Our supplier partners offer excellent technical support and we work collaboratively with resin producers to ensure that our offering is fully compatible and will provide the required performance at a competitive total cost.

Our product categories in this business segment include:


Our fillers not only reduce cost but also impart performance improvements that might not otherwise be achieved by the reinforcement and resin ingredients alone. Important properties, including water resistance, weathering, surface smoothness, stiffness, dimensional stability and temperature resistance can all be improved through the proper use of fillers.
