Ultrason® (PSU, PESU, PPSU) for household and catering: stylish, durable and safe

The demands on household appliances and catering articles are manifold and uncompromising at the same time: They have to be stylish as well as durable, they should be easy as well as safe in usage and they have to comply to legal regulations.

With its Ultrason® portfolio, BASF offers the ideal material for stylish, durable and safe applications in the food packaging and household sectors. The Ultrason® product range comprises polyethersulfone (Ultrason® E), polysulfone (Ultrason® S), and polyphenylsulfone (Ultrason® P) - transparent, high-temperature resistant thermoplastics which keep their excellent mechanical properties and dimensional stability over a wide temperature range.

Because of their unique property profile all Ultrason® grades offer great design freedom, can easily be colored and substitute glass, metal, ceramic and porcelain. What is more: They also contribute to a sustainable lifestyle and circular economy by being reusable many times without loss in mechanical properties and design – ideal for many to-go applications and multi-cycle food packaging systems!

With Ultrason® P you can create the perfect bottle – for every need. 

Everyone deserves their perfect bottle – made of Ultrason® P (PPSU)

The BASF polyphenylsulfone (PPSU) can be manufactured in all state-of-the-art production methods. It can be used to produce bottles for adults but also for babies as it contains no harmful substances, is approved for food contact and has outstanding strength, chemical resistance and long-term high-temperature stability. 

Bottles made from the transparent, slightly honey-colored polyphenylsulfone can easily withstand hot steam sterilization. These properties ensure that especially baby bottles made of Ultrason® P are safe to use, while being lightweight and shatter-proof.

• Very high, long-term service

• Temperature resistance up
   to 180°C (short-term up
   to 220°C)

• Good dimensional stability

• High stiffness

• High mechanical strength

• Excellent hydrolysis           

• Resistance to superheated

• Stain resistant:
   no discoloration

• Break resistant

• Very good toughness and
   impact resistance

• Exceptional chemical

• Available in transparent or 
   colored with Colorant
   Chromatics™ by Avient

Especially in the household and catering industry the request for brilliant colors in both transparent and translucent shades as well as full-colored materials is high. BASF is cooperating with Avient Corporation to globally offer colored grades. These feature BASF’s Ultrason® as high-quality base polymer combined with Avient’s Colorant Chromatics™ high-temperature color formulation expertise for color concentrates and pre-colored solutions. The colored grades will be formulated and sold by Avient as Colorant Chromatics™ made with Ultrason® by BASF.

Your key benefits from our color partnership:

  • You can place various-sized orders with short lead times.
  • You have access to comprehensive technical support from the base polymer to the final-colored product.
  • You can quickly react to design trends.
  • You can increase your speed to market.

You want to develop colorful household appliances or catering articles with PAES? To discuss your color requirements, please contact BASF or go to Avient Design – specialized industrial designers who also understand materials and molding. We can help to simplify your entire process to accelerate time to market and create products that win with your customers.

It is now possible to produce marbled serial components made of Ultrason®. The coloring technique opens up virtually unlimited possibilities for designers to use BASF's polyarylethersulfones (PAES) to color household appliances, catering bowls and containers. For the first time, surface effects such as color shades, color streaks and patterns can be reproduced: Injection-molded parts of one series look alike but are not completely identical - for the production of one-of-a-kind parts, which at the same time benefit from the outstanding properties of Ultrason® in terms of mechanical, thermal and chemical resistance as well as approval for food contact.

Ultrason® Kapiteltitel Reusable

GO REUSABLE – This is how you can support a circular economy!

With Ultrason®, reusable, high-quality and stylish household and catering articles with exceptional use properties over a long life-time can be developed. These products can be reused by consumers and recirculated by caterers many times while maintaining performance and design. By this, they support a circular economy for food packaging, avoiding single-use plastics and reducing packaging waste caused by conventional catering, take-away and to-go articles. Thus, reusable catering and to-go articles made of Ultrason® can be part of a multi-cycle system that saves valuable resources and avoids packaging waste as targeted in the Single-Use Plastics EU Directive 2019/904.

Best in contact: Excellent chemical resistance of Ultrason® against foods, cleaning agents and care products

Ultrason® Household 8134

BASF tested the stress cracking resistance of Ultrason® to different foods, cleaning agents and care products to make sure that household and catering articles keep their quality and high performance during their entire lifetime and in different stages of usage: when in contact with food, when being cleaned and when touched in handling.

The result: Different Ultrason® grades showed no stress cracks or discoloration, thus proving that they are resistant to all tested media.
