For the production of fiber-reinforced plastic profiles and plastic tubes
Our polyester-based technical nonwovens ensure that you get optimal surface coverage of your composite.
Pultrusion is a dynamic process in which the reinforcing material, after passing through a resin bath, is drawn through a tool (tempered mold) to produce a consistent product. Because the process is dynamic, inserting a surface mat is an optimal way to provide the composite with a wide range of surface properties.
- composite in wind turbines
- carrier material in manhole covers
- pultruded profiles in chemical plant construction, window construction, building construction, lightweight construction
Our products are convincing due to:
- high-quality surface finish
- reduced reinforcement print through
- elimination of surface penetration of reinforcing fibers
- improved corrosion resistance
- improved resistance to UV discoloration and degradation
- surface conductivity
- improved wear and impact resistance
- white/black polyester based synthetic veils for general purpose GRP pultrusions
- antistatic polyester-based synthetic veils with tailored levels of conductivity for profiles such as cable trays and ladders, mining ducts, support and access structures in petrochemical and offshore plant etc.
- para-aramid veils for improved impact and wear resistance
- pre-ox based veils for enhanced fire resistance
- available in various basic weights
- widths upon request
In addition to the enhanced properties of the pultruded profile, a synthetic surfacing veil such as those manufactured by Norafin also improves the pultrusion process itself giving:
- reduced die wear
- reduced pulling forces
- increased line speeds
The use of a surfacing veil with isotropic properties also gives a significant degree of hoop strength to pultruded profiles such as tubes, 'L' sections and 'U' channels where the main reinforcement is unidirectional.
