This material is valued in the plumbing industry for its strength, light weight, and resistance to impact and various chemicals, making it suitable for drain installations and various plumbing applications. ABS is typically black in color and is preferred in certain applications due to its ability to withstand lower temperatures compared to other plastics, such as PVC.
