HIGH TEMPERATURE PLASTICS | MATERIALS
Suppliers of high-temperature resins and compounds are continuing to improve their materials, ranging from PA and PPA to PEEK and even crosslinked thermoplastics. Peter Mapleston finds out what’s new
Competition heats up in temperature resistance
When it comes to thermoplastics with high tem- perature resistance, processors and application specifiers have never had as much choice as they have today. Offerings in semi-crystalline and amorphous materials continue to improve and expand. That’s especially true when it comes to polyphthalamides (PPAs), the so-called high temperature nylons, but not only these materials. Polymer producers and compounders have in recent months introduced new polysulphones, polyphenylene sulphides, polyesters, polyaryleth- erketones, and even crosslinkable thermoplastics. Solvay was the first company to market with a
PPA, branded Amodel. Thirty years on, its newest material is Amodel Supreme, a PPA polymer that is claimed to offer the highest performance on the market. The original Amodel was based on polyam- ide 6T (the T stands for terephthalic acid). Solvay does not say what type of PPA the new Amodel is.

“Amodel Supreme PPA features the industry’s highest glass transition temperature (Tg) of 165°C, and it delivers superior mechanical performance between 140 and 200°C,” says Brian Baleno, Head of Marketing and Business Development, Solvay Specialty Polymers global business unit. The new polymer also improves electrical
property performance, including volume resistivity and dielectric strength above 150°C. Solvay says this creates new opportunities for PPA to be used in higher voltage rotating electric systems, such as next-generation traction motors, inverters and power electronics. Amodel Supreme PPA products are built on
Solvay’s new 9000 Series base resin. They are available in 33% and 50% glass fibre-filled resins for standard grades (metal replacement), structural grades (thicknesses over 3mm) and grades targeting automotive electrification. All materials
