PU Fenestration Systems

The polyurethane resın system is a new pultrusion process. The two components of polyurethane, isocyanate and polyol, are pumped out by a special injection machine according to a certain proportion and fully mixed before entering the injection box. After the glass fiber and polyurethane resin in the injection box are fully soaked, they enter the pultrusion mold together, solidify at a certain temperature, and pull out the profiles continuously.

Heat resistance

Higher thermal deformation temperature and Barcol hardness;

Drop resistance

Better tatigue resistance;

Holding force

With better nail holding force, self tapping screws can be directly used;

Production

No smoke and odor generated during production, zero VOC;

Strength

High transverse strength of the product;

Stability

High dimensional stability and smaller shrinkage;

Pure fiberglass

Complex cross section can be produced by pure fiberglass, such as door and window profiles;

Spraying treatment

It can provide better product surface. If spraying treatment is required, it can be sprayed without surface treatment;
