Polyphenylene Sulfide reaches crystallinity without hot oil.

Press Release Summary:

With Fortron® ICE Improved Crystallization Evolution Grades, injection molders that use hot molding systems, operating at temperatures greater than 275°F, can minimize cycle times and number of broken parts. Molders with cold injection units, operating at temperatures from 194–275°F, can achieve full crystallization. In addition to chemical and thermal resistance, semi-crystalline polymer offers high hardness and rigidity with low creep and moisture absorption.

Celanese to Introduce Fortron® ICE PPS with Improved Productivity and Properties at K 2013

Next Generation PPS ‘Opens Up Significant and New Design Spaces’

Sulzbach, Germany, Florence, Ky., Shanghai, PR China, – Celanese Corporation (NYSE: CE), the global technology and specialty materials company, today announced it will introduce the next generation of polyphenylene sulfide (PPS) — Fortron® ICE (Improved Crystallization Evolution) with improved productivity and properties — at K 2013 in Düsseldorf, Germany.

“These innovative ICE grades from Celanese provide all the known performance benefits of Fortron PPS plus unmatched processability, which opens up significant and new design spaces,” said Barry Daggs, Celanese global business line director. “Now, Fortron PPS can reach full crystallinity in molding without hot oil technology, while maintaining its excellent property profile. This exciting development opens new business and end-use application opportunities.”

The introduction of this next generation Fortron PPS is one of several Celanese is scheduled to make at booths A07 and B07 in Hall 06 during K 2013. The new Fortron ICE grades use an innovative platform technology developed by Celanese material scientists that delivers material properties that are equivalent to or better than standard injection molding Fortron PPS grades and significantly improves the processing characteristics.

“Successful field trials and tests, using a variety of equipment for injection molding diverse part shapes, demonstrate that new Fortron ICE grades can help customers stay competitive by reducing cycle times, scrap rates and overall production costs, as well as improve flatness and enable easier demolding,” Daggs said.

Injection molders that use hot molding systems, operating at temperatures greater than 135 degrees Celsius (275 degrees Fahrenheit), can:

• Reduce molding cycle times, providing production cost savings and increasing net operating capacity

• Improve demolding of parts, decreasing the number of broken parts and reducing costly rework

In addition, molders with cold injection units, operating at temperatures between 90 degrees to 135 degrees Celsius (194 degrees to 275 degrees Fahrenheit), can achieve:

• Full crystallization at lower temperatures, opening new opportunities without the additional cost of hot molding equipment

Fortron PPS offers excellent chemical and thermal resistance, high hardness, rigidity and dimensional stability, and low creep and moisture absorption. This specialty semi-crystalline polymer is often used to replace metals and thermosets in various automotive, electrical/electronics, aerospace, fluid handling and industrial/consumer applications.

The next generation Fortron ICE 504L is listed by Underwriters Laboratories as UL-94 V0 at 0.38 millimeters thickness. Additional approvals for Food and Drug Administration approvals and drinking water are available upon request.

“These innovative Fortron ICE grades from Celanese are ideal options for customers who want to save more on their processing costs as well as free up more machine time,” Daggs said. “This, in turn, helps them to increase capacity without expending capital.”
