SABIC launches new resin for automotive applications

SABIC, a global leader in the chemical industry, has introduced Noryl GTX 9500 resin, a new addition to its family of unfilled Noryl GTX resins, offering excellent dimensional stability under high temperature and humidity conditions
.

Compared to polyamide (PA) resins (PA66 and PA6), SABIC's Noryl GTX 9500 resin maintains a better balance of mechanical properties and has a comparable high Flow and high temperature properties
.
Its dimensional stability and retention of mechanical properties - coupled with high flow properties - over a wider range of temperature and humidity conditions can provide opportunities for weight-saving thin-wall designs
.

Target applications for Noryl GTX 9500 resin include automotive junction boxes, connectors and other applications requiring dimensional stability
.
These materials also demonstrate their potential as base resins for carbon fiber-reinforced thermoplastic composites
.
Carbon fiber reinforced thermoplastic composites can be used for structural and body components, as well as applications in the industrial, aerospace and marine markets
.

Darpan Parikh, head of global product management for resins and compounds in SABIC's Specialty Products business unit, said: "Our global development team is skilled in formulating thermoplastics with targeted properties to solve long-standing customer challenges, such as nylon's performance in moisture exposure.
Tendency to soften

Shinsuke Nakamoto, Senior Business Manager, Noryl Portfolio, Asia Pacific, SABIC's Specialty Products Business Unit, added: "We designed Noryl GTX 9500 resin to provide our customers with innovative new material options for those who must maintain their shape in high temperature, humidity environments.
and performance applications
.
The introduction of this new grade demonstrates our leadership in materials innovation and our focus on continuous improvement and expansion of our product portfolio

Withstands heat and humidity

PA resins have a strong tendency to absorb moisture and water, and this tendency is exacerbated at elevated temperatures, which may lead to softening, reduction in hardness and warping
.
Noryl GTX 9500 resin has significantly lower water and moisture absorption than PA, even at high temperatures up to 150 degrees Celsius
.
In fact, testing by SABIC shows that Noryl GTX 9500 resin absorbs 21% less moisture than PA66 at equilibrium and 58% less than PA6
.

Hygroscopicity at equilibrium, Noryl GTX 9500 material surpasses PA in dimensional stability
.
The total dimensional change (flow and cross-flow) at equilibrium for 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 for lower scrap, and thinner walls, supporting lightweight designs
.

Noryl GTX 9500 resin also exhibits excellent mechanical properties - flexural modulus, tensile modulus and flexural strength - in wet conditions compared to PA66 and PA6
.
In addition, this material surpasses existing PA-based Noryl GTX grades in water and moisture absorption, dimensional stability and performance retention
.

SABIC's new Noryl GTX 9500 resin is available worldwide
