Material

Thermosetting resin grade:

“PR100” grade
180 °C thermal endurance matrix

“PR200” grade
Epoxide matrix; used for high mechanical and thermal resistances

“PR300” grade
Phenolic matrix used for fire resistance and chemical resistance

“PR400” grade
Methacrylate Methyl matrix; Fire resistance

“PR500” grade
Polyester matrix; basic formulation

Série « PR600 »
Vinylester matrix used for corrosion and fatigue resistance

Reinforcement types:

The GDP pultruded are a combination of continuous reinforcements and an organic polymer. The reinforcement weight varies from 40 to 80%, according to the requirements.
The reinforcements most commonly used are based on:

-Glass fibers
-Aramid fibers
-Carbon fibers

Colouration

The pultruded colour can be obtained either in the core of the material by pigmentation or on the surface by painting.

Coextrusion

-The best way to associate properties of thermoset and thermoplastic profiles.
-GDP can extrude on line a thermoplastic material directly on the pultruded shape. This thermoplastic coating can be partial or overall surface.
- Following materials are available for coextrusion:
· PP and PE polyolefines
· PA6, PA66, PA12 polyamides
· Others: ABS, PET, PC, PMMA…
· Alloys: PP/PA, PE/PA, PC/ABS…
- Elastomers are also compatible with coextrusion process.
