Composite profiles are known under lots of names - GRP, FRP, CRP, glassfibre or carbonfibre profiles. We produce it by a pultrusion technique from resin and reinforcing elements. Polyester resin is applied as a matrix most frequently; epoxy, vinylester, acrylate and other resins are used for special applications. In most cases, glass fibres are used as reinforcement, but carbon or aramid fibres are applied too. Depending on the properties required, straight fibres (rovings), various types of mats or fabrics or their combination are chosen.
5M produces standard pultrusion profiles, but also a lot of profiles tailored to customer requirements – profiles specific in shape for application in various industries.
As the leader in the field of composites, we are the first in Europe to introduce a composite pultrusion profile made from polyurethane. In comparison to common resins used in pultrusion, this composition has several unrivalled advantages. The combination of polyurethane and glass reinforcement we achieved excellent properties of the final composite profile!
Looking for material which is impact resistant? Which is lightweight, chemically resistant, has excellent strength and is easily machined? So the polyurethan pultrusion is the right solution for you!
It is very interesting to compare characteristics of common used material with composites. In below mentioned tab you can find out main advantages.
