Sabic launches new resin product that is more resistant to heat and humidity than PA

Recently, Sabic has introduced a new product in the unfilled Noryl GTX resin grade series - Noryl GTX 9500 resin, which is a blend of nylon (PA) and modified polyphenylene ether polymer (PPE) resin, which can withstand high temperature and humidity conditions.
Offers excellent dimensional stability, solving the challenging challenges of automotive applications
.

Compared to PA66 and 6 resins, Sabic's Noryl GTX 9500 resin reportedly maintains a better balance of mechanical properties when exposed to the high temperatures and humidity of a typical automotive under-the-hood environment
.
It also has similar high flow and high temperature performance, according to Sabic
.
Dimensional stability, retention of mechanical properties, and high flow properties of the material over a range of temperature and humidity
.

Target applications for Noryl GTX 9500 resin include automotive junction boxes, connectors and other applications requiring dimensional stability
.
The material also shows potential as a base resin for carbon fiber-reinforced thermoplastic composites for applications in structural and body components as well as industrial, aerospace and marine markets
.

"Our global development team excels at formulating thermoplastics with targeted properties to address longstanding customer challenges such as nylon's tendency to soften in wet environments,
" said Darpan Parikh, head of global product management, Resins & Compounds
.

"We designed Noryl GTX 9500 resin to provide our customers with innovative new material options for applications that must maintain shape and performance in high temperature, humidity environments,
" added Shinsuke Nakamoto, senior business manager, Asia Pacific, Noryl portfolio
.

The tendency of PA resins to absorb moisture and moisture, exacerbated at elevated temperatures, can lead to softening, loss of hardness and warping
.
Noryl GTX 9500 resin has significantly lower water and moisture absorption than PA, even at elevated temperatures up to 150°C
.
In fact, Sabic's tests show that Noryl GTX 9500 resin absorbs 21% less moisture than PA66 at equilibrium and 58% less than PA6
.

Sabic's Noryl GTX 9500 material is hygroscopic at equilibrium and has greater dimensional stability than PA
.
The total dimensional change (flow and cross-flow) of Noryl GTX 9500 resin was 0.
29% compared to 84% for PA66, which was 165% higher than Noryl GTX 9500 resin
.
This improved dimensional stability provides benefits for moisture-sensitive applications, including reduced warpage to minimize scrap, and thin-wall designs to support lightweighting
.

Noryl GTX 9500 resin also has excellent retention of mechanical properties (flexural modulus, tensile modulus and flexural strength) in wet conditions compared to PA66 and PA6
.
In addition, the material exceeds existing PA-based Noryl GTX grades in terms of water and moisture absorption, dimensional stability and performance retention
