Grooved Balsa Wood for Wind Power Industry

Product Description

Balsa wood is an eco-friendly natural material with a unique cell structure like honeycomb with exceptional performance features such as low weight, strong fiber and  high rigidity.

Balsa Core is derived from a natural resource that can be found in South America. The tree is milled, kiln dried, qualified and transformed into the final core. Among the family of the Core Materials, Balsa is the preferred material due to its ecological status, fast renewability and environmental friendly status.

COATING PROCESS
Our resin formula mostly known as coating will seal the panel to reduce the absorption of other resins during the manufacture of the Composite as well as enhance the flow of resin into the application. The Formula is spread among the panel surfaces closing the cells after the cut. The appearance will give the panel a slightly darker color.

FLEXIBLE PANEL
The Flexible or Contoured Panels are processed from our Rigid Panels with light backed fiberglass Scrim and score grid cut that can allow the materials to take any shape regarding the customer usage where the application area is not flat.

Rigid Panel                                                    
Sized into our standards of 610mrn x1220mm, the Rigid Panels are the core material in the primary production stage. This material is mostly used in flat applications such as the construction, sports, boating and automotive stage industries, among others.

GROOVING& PERFORATION
The grooving and perforation are production methods that improve the flow of the resin among the Structure where the composite is applied. Both of the processes are commonly used in the Wind Power industry.
