Polyurathane Pultrusions PU (polyurethane) pultrusion parts provide extremely superior mechanical strength compared to other resin systems like polyester and vinylester. It provides about 3 times more strength than polyester or vinylester resin pultrusions. Another most advanced property of Polyurathane pultrusions is that it provides exceptional interlaminar shear strength. Combining mechanical strength and interlaminar shear strength, you can design your pultrusion walls super thin and save material costs. Because of the uni-direction of fiber construction in pultrusions, pultruded parts usually crack along the fiber direction when applied a self tapping screw. Polyurathane resin system perfectly solved this problem for your pultrusions.
The pultrusion process and knowhow of polyurethane resin system is totally different from other resin systems. HAMC has successfully worked a most complicated profile out of polyurethane resin system in China. Please contact us for your specific & special pultrusion requirements.
