BASF Ultrason PESU used in extractor lens of coffee brewers

American coffee brand Bruvi uses BASF’s polyethersulfone (PESU) Ultrason E 2010 to manufacture the extractor lens in its coffee brewers.

Extractor lens of Bruvi’s coffee brewer is made of BASF’s Ultrason PESU.

The complex injection-molded component is part of Bruvi’s unique auto-optimized brewing technique, scanning the coffee pod and then automatically adjusting the brewing parameters to the specific recipe for the optimal brew of each individual coffee.

BASF’s PESU Ultrason E 2010 contributes to the durability of the machine by its excellent mechanical strength, its high heat and steam resistance up to 180°C, as well as dimensional stability at varying temperatures.

The high-quality thermoplastic Ultrason E 2010 is approved for food contact according to American, European and Chinese specifications.

“We selected Ultrason because it supports our advanced brewing technology: It is safe to use and also withstands the high pressure and hot steam occurring during coffee making,” said Sung Oh, Co-Founder of Bruvi.

In addition, the medium-viscosity grade Ultrason E 2010 can be smoothly injection-molded and easily assembled with screws because of its very good mechanical properties. The extractor lens made of Ultrason E 2010 is overmolded with rubber so that the coffee capsule sits tightly and no water runs into the machine.

Ultrason is the trade name for BASF’s product range of polyethersulfone (Ultrason E), polysulfone (Ultrason S) and polyphenylsulfone (Ultrason P). The high-performance thermoplastic is used to manufacture water filtration membranes, stylish, durable and safe household and catering applications as well as lightweight components for the automotive and aerospace industries.

With extraordinary property profile, Ultrason brands can substitute thermosets, metals and ceramics in many applications.
