Pittsburgh, Pennsylvania -- Bayer MaterialScience llc of Pittsburgh has strengthened its strategic collaboration with Pultrall Inc., a Canadian manufacturer of pultruded composite profiles for such markets as automotive, medical, utilities, agriculture and construction.
The aim is to capitalise on the combined expertise of Pultrall and polyurethane systems marketed through BaySystems, according to Mario Guenette, sales manager, Pultrall, and Harry George, head, Diversified Industries, New Applications, NAFTA, Bayer MaterialScience.
"We're delighted to be strengthening our relationship with Bayer MaterialScience, a respected and market-leading polyurethane provider," said Guenette. "Our companies are a good fit because we share a mutual interest in the importance of investing in research and development to spur continued innovation for the benefit of industry and our customers."
Founded in 1987, Canadian-based Pultrall has had a relationship with BMS for five years, boosted when BaySystems supplied Pultrall with Baydur PUL 2500, a two-component liquid polyurethane system for use in making composites, Guenette said. The material is marketed by BaySystems, BMS' global PU systems business.
"Several industry experts have shown great interest in pultruded composite parts that use the Baydur product," Guenette said. "The material stands out from competitors because of its resilience, impact resistance and strength."
"The Baydur system also enables us to avoid using mats or wovens in profiles," Guenette said. "Using the polyurethane resins system as the transfer reinforcement material enables us to make the profile with zero degree reinforcement, which is more cost efficient."
Pultruded products are fibreglass-reinforced shapes formed in a continuous process that gives an end product with extraordinary strength. The base reinforcement material is pulled through a resin bath and then through a heated die, giving the part a final shape designed to meet customer specifications. Pultrusion allows parts to be made in a wide variety of shapes and lengths. Variations of properties such as strength and of colour, can be obtained by changing the combination of resin mixture and reinforcement materials.
Typical outlets are bus side panels; modular display duct panels used on buses, trains, and other means of transport for air circulation and to house lighting systems; overhead luggage racks; and automotive structural components.
The Baydur system has been specially designed for use in pultrusion and gives excellent composite properties, including superior elongation at break, shear strength and impact resistance, according to George.
