Ossberger Pressblower uses Huntsman elastomers to make automotive parts

DUESSELDORF, Germany—At K 2022, Ossberger GmbH is displaying the latest version of its Pressblower blow molding machine, which produces automotive parts based on elastomers materials from Huntsman.

The Pressblower SB2-260 is described as "a brand-new injection blow molder designed to produce gaiters for air springs for the automotive industry."

To demonstrate its precision molding capabilities, Ossberger produces the components from Huntsman's Irogran A 92 E 4860 thermoplastic polyurethane.

The gaiters, which have a net weight of about 150 grams (0.33 pounds), can be produced within a cycle time of 27 seconds, according to a Huntsman release about the K 2022 exhibit.

Boots and bellows produced on Ossberger's Pressblower machines are used in around 90 percent of automotive vehicles worldwide, the materials supplier noted.

The Irogran TPU, it noted, is a polyester-based elastomer designed for use in thick- and thin-walled parts, thick-walled profiles, pneumatic tubes and film and sheet products.

Features are said to include high melt stability and ease of processing for shorter cycle times, excellent wear performance, lightweight and high resistance to dynamic stress, abrasion and grease.
