Pultrusion profiles with a variety of resins

The pultrusion profile can be tailored by varying the type of resin, especially when the need is to adapt the chemical and/or physical properties of the profiles. When a client has specific requirements in this area, we will look for special resins or additives to meet these requests.

Below some examples of specific wishes that are possible:

• Higher temperature resistance / glass transition temperature (Tg)
• Modified surface quality
• Improved bonding
• Increased fire safety (flame retardant)
• Increased chemical resistance
• Deviating colours (special profile colours)

Here are some examples of resin types with certain specific properties and advantages:

Epoxy resins – Bisphenol A / Anhydride curing

Mainly used in high-grade structural components. It offers very good mechanical and dynamic properties, as well as enhancing bonding. The thermal and chemical properties are also excellent.

Epoxy resins – Aliphatic polyamine curing

Offer very good physical properties and have a high chemical resistance. On top of that, they have very favourable anti-ageing characteristics and toxicological properties. These resins are often used in food and health related applications with USP and FDA standardisations.

Bismaleimide (BMI) resins

BMI resins are very tough and offer high temperature resistance (Tg up to 250-300 °C). The superior mechanical and thermal properties allow this resin to be applied increasingly often for the manufacture of high-grade structural composite components for industries such as aerospace.
