Ultradur® HR (Hydrolysis Resistant) PBT and Ultradur® HR + NaOH (Sodium Hydroxide) Resistant PBT

The most recent addition to the Ultradur® PBT (polybutylene terephthalate) family of products is a line of HR (hydrolysis resistant) grades.

The most recent addition to the Ultradur® PBT (polybutylene terephthalate) family of products is a line of HR (hydrolysis resistant) grades. The new Ultradur® HR PBT grades are designed for applications that demand mechanical property retention, during exposure to high heat and humidity. In addition, Ultradur® HR PBT is laser weldable for easier component assembly and has higher flow properties delivering measurable processing benefits over standard PBT grades. The higher performance of the Ultradur® HR PBT grades has led OEMs and component manufacturers to specify these grades for several applications including connectors, crash sensors, and wheel speed sensors. more...
