PC/ABS is the most mature alloy material, and on the basis of retaining most of the mechanical properties of PC materials, it has better improved the poor flowability of PC materials. At the same time, halogen-free flame retardant PC/ABS materials are currently in OA systems such as laser printers, inkjet printers, fax machines, laptop computers, and digital toys. PC/ASA has better weather ability than PC/ABS and is more suitable for outdoor products.

PC/ABS as the world's largest sales of commercial polymer alloy, in recent years with about 10% of the growth rate of demand.

Compared with PC, PC/ABS improves the fluidity, improves the processing performance and reduces the sensitivity of products to stress. Therefore, PC/ABS is widely used in high strength and high heat resistance parts such as automobile interior, exterior decoration and headlights.

With the improvement of people's awareness of environmental protection and the introduction of environmental protection and recycling laws and regulations such as ELV in the automobile industry, raw material manufacturers continue to provide new solutions.

As a leader in the engineering plastics industry, it timely launched a new generation of PC/ABS alloy series materials, which mainly includes hydrolysis resistance and stability of PC/ABS, ultra-low gloss PC/ABS used for non-spraying interior decoration, excellent chemical resistance and not easy to be eroded by paint and other chemical solvent PC/ABS series products.

Resistant to hydrolysis and stable PC/ABS

Hydrolytic stability resistant series PC/ABS (HAC8250R) is mainly used in automotive interior products such as automotive dashboard skeleton.

As the supporting structure of the whole instrument panel, the importance of the automobile dashboard skeleton is self-evident, so the OEMs put forward more stringent requirements for the materials of the instrument panel.

At present, the dashboard skeleton not only requires good mechanical properties, processing performance, but also excellent hydrolysis resistance and thermal aging performance, in order to adapt to the car in the extreme high temperature, high humidity environment.

In PCT (Pressure Cooker Test) Test, after 1000h at 95%RH and 100℃, the molecular weight of PC phase in the new generation of PC/ABS remained more than 90%, and no serious hydrolysis occurred.

However, the impact performance of the alloy only decreases by 15%, which improves the performance by more than 30% compared with ordinary PC/ABS.

In addition, in order to meet the requirements of thin-walled instrument panels, this series of materials reduces the viscosity of materials under high shear, and overcomes the disadvantages of thermal decomposition of materials caused by unilaterally increasing the temperature to improve the material fluidity in the past.

The new generation of hydrolysis resistant and stable PC/ABS materials can even be recycled due to their good hydrolysis resistance and thermal stability.

When less than 25% recycled material is added, the multi-axial impact performance of the material only decreases by 11%, and the material is ductile fracture, which fully shows the superior performance of the new generation PC/ABS.

At the same time, this series of materials have also been evaluated by the public laboratory, after 80%RH, 90℃ high temperature and humidity hydrolysis for 600h, notch impact strength only decreased by 8.5%.

At present, the material has been used in Volkswagen Passat, Chrysler 300C, GM Buick and other models.
