Versatile plastic for complex molds

Amazing diversity

Despite the rapid pace of progress in plastics technology, many molded parts are still produced from glass fiber-reinforced plastics using time-consuming processes which involve a great deal of manual input. Now, plastics experts from Bayer MaterialScience have developed a particularly cost-effective and also very environmentally friendly new process that can be automated.

Styrene-free, environmentally friendly spraying process

The new product, called Multitec® Short Fiber Spraying, is a multi-component polyurethane system for spray application. It allows molded parts to be produced with varying structures by combining solid and foamed layers. This completely eliminates the need to use styrene, which is hazardous to health. Additionally, the plastics experts at Bayer use water as an environmentally-friendly blowing agent to foam the plastic.
