NORYL GTX™ Resin

Inherently conductive NORYL GTX™ resins offer automotive OEMs design advantages with large, high-precision body panels and complex fenders by allowing for existing process integration including high-heat on-line painting systemS all while providing outstanding esthetics and performance.

NORYL GTX conductive alloys of polyphenylene ether (PPE) and polyamide (PA) decrease the coefficient of thermal expansion (CTE) by up to 20 to 40 percent vs. previous grades, allowing for increased dimensional stability.

• Large, top-quality, high-precision
• Consistent long-term dimensional stability
• Higher-heat online painting systems
• Outstanding esthetics + performance
• Enhanced conductivity at higher temps while maintaining excellent mechanical properties

• The resin can withstand a broad range of temperature extremes from 220°C during assembly to -40°C during in-use applications. The higher heat soak capability of up to 220°C for up to 60 minutes helps to ensure mechanical and esthetic property retention during unexpected down time on a production line.
• Documented ductile low-temperature impact performance to protect critical automotive components by providing superior energy absorption, allowing OEMs to design with less packaging space without sacrificing protection performance.
• Outstanding hydrolysis resistance and dimensional stability vs. PBT, protecting automotive components from polymer breakdown due to moisture exposure, and providing enhanced property retention and dimensional stability vs. PA6 & PAG, 6.

 Our customer tell us that safety is of the outmost importance. Common electric vehicle battery side impact countermeasures are forged from multi piece steel stamping and extruded aluminum profile. Such solution are heavy at a time when weight saving is increasingly desired.

SABIC's Speciality business can offer singe-piece, lightweight side impact counter measure fashioned from engineered honeycomb structures using NORYL GTX™ resin, saving our customer to multi-piece metal reinforcements

Lightweight, Heat Resistance and Design Freedom

Automotive designers look for new ways to stand out from the crowds with esthetically appealing designs and outstanding technical performance. Wheel inserts help to reduce drag and hence improve the range of electric vehicles. Automotive designers can realize exciting, customizable new designs in a cost effective way.

NORYL GTX resin is an alloy of polyphenylene ether (PPE) and polyamide (PA), combining the inherent properties of PPE (long-term dimensional stability, very low moisture absorption, stiffness, strength, impact resistance) with the chemical resistance and flow of PA.

This advanced thermoplastic allows for new concept designs while providing superior mechanical properties and lightweight solutions that can withstand tough environments.

Rail extensions play a crucial role in energy absorption of frontal & rear crashes.

NORYL GTX™ resin is a semi-crystalline alloy of polyphenylene ether (PPE) and polyamide (PA). This alloy combines the inherent benefits of PPE (robust FR, heat resistance, excellent long-term dimensional stability, low creep, good impact resistance) with the benefits of PA (chemical and impact resistance and flow).

The result is a chemically resistant material with the stiffness, impact resistance and heat performance required for e-coat and on-line painting. The low density of unfilled NORYL GTX resin can provide part-weight savings of up to 25% over glass or mineral filled resins.

Additionally, NORYL GTX resin may provide sustainability benefits due to its light weight and may be considered for exterior body panels, in-and-on-line painted parts, and EV battery protection.

Metal/plastic hybrids are highly engineered solutions for critical structural elements that can help promote vehicle safety. They can provide valuable solutions to a number of situations, allowing for the realization of greater system cost reduction, enhanced design freedom, weight out and better long-term performance. The incorporation of NORYL GTX™ resin in metal/plastic hybrids can provide several benefits as mentioned above, beyond many of the traditional automotive materials such as PA6,6 and PBT.

NORYL GTX™ resin is E-Coat process capable and maintains its shape, even while supporting additional loads. Additionally, NORYL GTX™ resin solutions can be up to 20% lighter than other engineering thermoplastics and up to 40% lighter than steel; allowing for lighter parts and superior fuel economy.

The NORYL™ resin family consists of multiple blends of polyphenylene ether (PPE) with complementary thermoplastics. NORYL resin is an amorphous blend of PPE with polystyrenes and it is widely used in ignition coils, sensors and battery housings. NORYL GTX resin is a semi-crystalline blend with polyamides and offers multiple commercialized solutions across internal combustion engine, hybrid and electric vehicles.

NORYL GTX™ resin combines the inherent benefits of PPE (robust flame retardance, heat resistance, excellent dimensional stability, low creep) with the benefits of PA (chemical resistance, flow and impact resistance). The result is a chemically resistant material with the stiffness, impact resistance and heat performance required for inline painting. The low density of unfilled NORYL GTX resin can provide part-weight savings of up to 25% over glass or mineral filled resins. Additionally, the low specific gravity of NORYL GTX resin makes it a candidate resin for significant lightweighting versus steel. Potential applications for steel replacement include exterior body panels, in or online painted surfaces, and battery protection.

Biofouling or biological fouling can be described as the accumulation of microorganisms, plants or algae on wetted surfaces. This leads to loss of efficiency of membranes and can shorten the lifetime and performance of pipes used in the transportation of drinking water. NORYL™ resin has unique properties, similar to stainless steel, that result in very low biomass production potential along with excellent hydrolytic stability even in chlorinated environments.

Typical Industry Requirements
• Hygienic and disinfectant (e.g. chlorine dioxide) resistant solution
• Reliable and long term part operation
• Potable water certified applications

NORYL™ RESIN Value

• Low biomass production potential
• Low surface roughness achievable
• High hydrophobicity
• Excellent chlorine resistance
• Potable water approved

NORYL™ RESIN Exhibits Biofouling Resistance That is Even Lower than Stainless Steel

The table on the right shows the biomass production potential (BPP) per material,
using Test Method 1 for EN 16421:2014. The growth of e.g. Legionella pneumophila,
which causes Legionnaires’ disease, begins when the biomass production potential is
>400 pg ATP/cm²*.

Other factors that influence biofouling:
• Surface roughness
• Degree of hydrophobicity
• Leaching of ingredients from plastics
