Limitations and Applications of PC/PBT Blends

2025-10-23

PC/PBT blends, while offering valuable material properties, present certain limitations that designers must consider. These materials exhibit medium flow characteristics, making them unsuitable for thin-wall designs. They are inherently opaque and demonstrate relatively high shrinkage rates during processing. Additionally, PC/PBT blends show susceptibility to chemical attack by bases, esters, ketones, and halogenated hydrocarbons, which may limit their use in specific chemical environments.

Despite these limitations, PC/PBT blends remain highly valuable for numerous applications due to their exceptional toughness and superior resistance to fuel and fluid stress cracking. These characteristics make them particularly well-suited for automotive and transportation components, including bumpers, rear fender outer panels, door handles, and tractor covers. In the household and consumer products sector, they are commonly used for chain saw housings and drill housings. Other applications include electrical housings and double glazing spacers, where their combination of mechanical strength and environmental resistance provides significant advantages.
