Components
Our GFRP laminate consists of an ECR glass fabric. It distinguishes itself by a high corrosion resistance against various chemical and physical influences.
Brandenburger offers two different versions. For the normal application in the earth, a UP resin (unsaturated polyester resin, acc. to DIN 18820 group 3; type 1140), which is temperature resistant up to 50 °C.
The second version is a VE resin (vinyl ester resin, acc. to DIN 18820 group 5; type 1310), which can be used under especially aggressive environmental influences.
Technical Components
- BBProtect® is available in widths of 100 to 800 millimetres and in lengths of up to 200 meters.
- Each layer of the material is about 0.8 mm thick.
- The most important measured prepreg characteristics (averages) standard BBProtect®
