What is Ultrason® S 3010

BASF Ultrason® S 3010 (PSU 3010) is a high-viscosity Polysulfone particle, specially designed for injection molding processing. It combines chemical resistance, stress crack resistance and toughness, and is suitable for application scenarios that require long-term reliability, such as laboratory equipment and household items. For manufacturers pursuing stable performance and processing efficiency, ultrason s 3010 offers a balanced and sustainable solution.

01 | Material highlights and procurement value

From the perspective of purchasers, the advantages of Ultrason® S 3010 lie not only in its physical parameters but also in its ability to address the pain points in practical applications:

Chemical resistance and stress crack resistance

  ・In laboratory equipment and chemical environments, materials are prone to erosion by cleaning agents, acids, alkalis or organic solvents. The chemical resistance and stress crack resistance of PSU 3010 ensure that the product can maintain structural integrity during long-term use and will not fail prematurely due to stress concentration.

  ・Solve the problem: Reduce product scrapping and after-sales costs caused by cracking.

Good mechanical strength and toughness

  ・The tensile strength is 75 MPa, and the impact toughness can still maintain 6.0 kJ/m² at a low temperature (-30°C), demonstrating the material's stability under extreme conditions.

  ・Problem-solving: Ensure that the products remain safe and reliable in the event of drops, impacts or cold environments, and reduce customer complaints.

Excellent thermal stability

  ・The heat distortion temperature (1.8MPa) reaches 177°C, and the long-term service temperature can be maintained at 155°C.

  ・Solution: Experimental equipment and household appliances suitable for high-temperature environments, avoiding precision failure caused by thermal deformation.

Electrical insulation and flame retardancy

  ・The volume resistance is as high as 1E15 Ω·cm, the insulation strength is 37 kV/mm, and the flame retardant grade is UL94 HB.

  ・Solution: Provide stable insulation protection for electrical components and laboratory instruments to enhance usage safety.

Processing adaptability

  ・The melt index (360°C, 10kg) is 40 cm³/10min, with excellent fluidity and suitable for precision injection molding.

  ・Solve the problem: Enhance production efficiency and reduce the defective rate during the processing.

03 | Technical process and processing compatibility

Ultrason® S 3010, as a high-viscosity PSU, is specially optimized for injection molding processes and features the following characteristics:

  ・Forming temperature range: It is recommended to carry out melting processing at 340-380° C. The mold temperature is suggested to be maintained at 160-180°C to ensure dimensional stability.

  ・Screw design suggestion: High-temperature resistant screw materials should be adopted to prevent material degradation at high temperatures.

  ・Mold compatibility: Suitable for forming thick-walled parts and transparent utensils, with a processing shrinkage rate of only 0.7-0.74%, which helps maintain part accuracy.

  ・Secondary Processability: Machining, bonding, and thermal welding are possible, facilitating post-processing in various application scenarios.

These process parameters enable buyers to better control yield and cost during mass production.

04 | Market Trends and Industry Dynamics

According to BASF's latest market news, the Ultrason® product line has seen significant growth in recent years in medical and laboratory equipment, heat-resistant consumer goods, and power tool components. In particular, in 2024, BASF announced the expansion of PSU production capacity in Germany and Asia to meet the rapidly growing demand for high-temperature-resistant transparent plastics in the downstream medical and electrical appliance industries.

  ・Medical and Laboratory: It can replace some glassware, reducing the risk of breakage.

  ・Home Appliances and Kitchenware: It is more heat-resistant and washable, meeting consumer trends for durability and safety.

  ・Electrical and Electronics: It meets the dual requirements of electrical insulation and high-temperature resistance.

For buyers, this means greater material supply stability and reduced future procurement risks.

05 | Customer Feedback

  ・A laboratory equipment manufacturer: Choosing Ultrason® S 3010 instead of traditional glass has reduced product scrap rates by 40% and significantly improved transportation safety.

  ・A customer in the home appliance industry stated: Using PSU 3010 for kitchen appliance housings solves the problem of plastic brittle cracking caused by long-term cleaning, extending the product lifecycle.

  ・An electronic device customer stated: Using it on electrical insulation components effectively reduces the risk of failure due to high temperatures or stress cracking.

These practical application feedbacks further validate the value of PSU 3010 in various industries.
