We did extensive research and testing before choosing Valmex in our boats. Valmex is manufactured by Mehler Texnologies in Germany. Mehler has been manufacturing high quality PVC for over 60 years. They manufacture nothing but high quality products. There are many cheaper PVCs, especially those manufactured in Asia that simply do not meet Weststream's requirements for a rubber boat of the highest quality and what our customers expect. This material is widely recognized as the best weldable PVC´ni in the world. We did extensive research and testing before choosing Valmex in our boats.
