BASF's Easy-Flowing PBT Is Now Available Here

Ultradur High Speed PBT, introduced at the K 2004 show in Dusseldorf last fall, is now available in North America.

Ultradur High Speed PBT, introduced at the K 2004 show in Dusseldorf last fall, is now available in North America. As we reported in February, this new PBT reportedly flows up to twice as far as standard PBT (depending on glass-fiber content) and reduces cycle times by up to 30% with no sacrifice in properties. Likewise, this PBT reportedly can incorporate higher filler/reinforcement contents to improve properties with no loss of processability. This feat is accomplished with an organic nano-particle additive that is soluble in the melt but forms a separate phase when the material cools. Commercial grades contain 10%, 20%, and 30% glass.
