Diab is a global company that develops, manufactures and sells core materials for sandwich composite structures used in, among other objects, leisure boats, wind turbine blades and components for aircraft, trains, industrial applications and buildings. The core materials have a unique combination of characteristics such as low weight, high strength, insulation properties and chemical resistance. The company has production units for material in Sweden, Italy, the US and China. Material processing takes place in the production units as well as in Lithuania and Ecuador.


The market for core material is growing due to the underlying demand for energy efficiency, which is leading to a greater need for high-strength, lightweight solutions. Wind turbines, leisure boats and various applications requiring the combination of light weight and high strength are the main application areas for the material.


At Diab, significant focus is given to safety. When Diab’s employees feel safe, the company is able to achieve increased productivity, and establish efficient lead times and deliveries to customers. Ethical business is also a core focus for Diab. Therefore, the company has policies, processes and activities in place to manage the risk of corruption and fraud.

Sandwich structures compensate for their carbon footprint in many applications during their life cycle.

Diab is the first company in the world within the field of composite materials whose science-based climate targets have been approved to lower its carbon footprint by 2050.
