The new Ultradur® High Speed PBT (polybutylene terephthalate) has significantly improved new flow properties delivering measurable benefits over standard PBT grades in a variety of applications.

The new easy-flow product is a really fast mover: depending on the glass-fiber content, it flows nearly twice as far as comparable standard Ultradur® PBT grades. Other characteristics of the polymer – like mechanical and thermal properties, density, shrinkage and hydrolysis stability – are not significantly affected by the process.

The key to this flow improvement lies in the addition of a nano structured additive developed specifically for PBT.

The good flowability of Ultradur High Speed makes the production of injection-molded plastic components less expensive and helps to save energy. These factors qualified the material to receive an eco-efficiency label from BASF. This label is awarded to products that perform better from an environmental and financial standpoint than comparable products.

Benefits for Injection Molders include:

	Advantages in Parts and Mold Design
	Lower Molding Temperature and Shorter Holding Times
	Faster Cooling Times
	Shorter Cycle Times
	Greater Output
