New Availability of Polyethersulfone (PES)

March 30, 2018

Conventus Polymers LLC, a leading distributor of high-performance engineering thermoplastics, has announced the North American availability of Paryls® polyethersulfone (PES) from China’s YOUJU (UJU) New Materials Co. Ltd. Conventus will be exhibiting Paryls® PES and other sulfones at NPE2018 this May 7-11 in Orlando, Florida (Booth #S10201 South Hall) .

Conventus has been an exclusive distributor for UJU New Materials Co. Ltd since 2013 and already distributes the company’s Paryls® polysulfone (PSU) and polyphenylsulfone (PPSU) product lines. “We welcome this new distribution arrangement, which expands our portfolio options for our customers,” said John Jorgensen, President of Conventus Polymers. The versatility of the sulfone family of materials makes them useful in many of Conventus’ key market segments including electrical/electronics, durable healthcare, high-performance plumbing, oil and gas, and firearms/defense. PES provides a broad range of performance benefits including high heat resistance, low mold shrinkage, and low smoke emission. Conventus is offering three PES grades (F2150, F2250 and F2350) with varying viscosities.

The demand for higher heat materials has grown significantly in the engineering plastics industry in a range of end-use applications such as consumer electronics, according to Jorgensen. “Although market penetration is typically measured in years for an overseas supplier like UJU, the company benefited from quick adoption at major OEMs due to severe supply storages in 2015 and 2016,” explained Jorgensen. “They have had lasting success based on the cost/performance value they offer customers.”

UJU New Materials built a successful business platform in Asia and expanded its sales presence globally in 2013. The company tripled capacity with a second manufacturing location in 2016 and commercially launched PES in late 2017. The company’s PSU and PPSU are used in a wide range of applications in the electronics, aerospace, and automotive industries.

North America is a key market segment for UJU New Materials, according to Steven Xu, Global Vice President of Sales and Marketing for UJU New Materials. The company’s line of sulfone products meets all regulatory requirements and offers similar performance to comparable grades, he said. Xu attributes the company’s rapid success in the U.S. market to its company culture. “UJU combines the entrepreneurship and cost structure typical of a Chinese company, with the commitment to quality and commercial approach of a western company,” said Xu.

Conventus offers unique expertise, combining problem-solving aptitude, deep technical knowledge, and strong relationships with key OEMs. The company’s highly focused approach within key end-use markets and its ability to develop new applications will be critical in expanding penetration of UJU New Materials’ sulfone materials in the U.S. and Canada.
