Gurit launches next generation balsa and PET core materials & new low toxicity epoxy laminating system

News International-French

15 Mar 2018

Advanced composites specialist Gurit introduces a core combination which is considered to be the future winning core materials solution. In addition, the Company launches Ampreg 30, a new low toxicity epoxy laminating system.

Gurit is launching the newly developed Balsaflex® Lite product with a novel coating system that is capable of reducing the resin uptake in infusion processes by up to 50% for rigid panels and by up to 40% for flexible balsa wood sheets. Thereby, customers are able to save cost through reduced resin absorption and achieve overall weight saving in the blade. Balsaflex® Lite offers superior mechanical properties, consistent high wood quality, good thermal stability and compatibility with epoxy and polyester resin infusion processes used by the industry.
 
Combined with Gurit`s Kerdyn® Green PET foam, manufactured from 100% recycled (post-consumer) PET materials, Gurit Balsaflex® Lite forms what Gurit considers the future winning core materials combination for the wind energy industry, which is ideally complemented by the existing range of Corecell® and PVC structural core materials.
 
Gurit Balsaflex® Lite samples are available as of now for Europe and North America. The innovative coating system will be launched to the Asian-Pacific market in the second half of 2018. Gurit Balsaflex® Lite is supplied in standard sheet size of 610x1220mm (2x4ft), thickness from 6mm up to 50mm and in the existing Balsaflex™ density range.
 
Gurit is also launching Ampreg 30, a new low toxicity epoxy laminating system for the manufacture of large composite structures in the marine, wind and construction industries. The new laminating system has been reformulated to prioritise user health and safety of hand lay-up and vacuum bagging production techniques through the careful selection of chemicals and the development of Light Reflective Technology (LRT) as a risk monitoring feature for the user.
 
Gurit Ampreg 30 features a robust resin matrix resulting in excellent mechanical and thermal properties of laminates produced at ambient temperature cures as well as moderate temperature post-curing processes. The laminating system is available with a range of hardener speeds from fast to extra slow, all applying the same simple mix ratio and the ability to blend hardeners to achieve a range of intermediate working times.
 
Gurit Ampreg 30 is available as of now globally. The laminating system comes in a wide range of pack sizes from small packs to drums and IBC containers. Ampreg 30 is also available as LRT (Light Reflective Technology) version, an optional addition to the resin matrix that enables inspection of contamination by means of UV light after each work period to reduce workers` exposure to chemicals and without changing the mixing and handling properties of the laminating system or cured resin performance.
