The NBS Abrasion Testing Machine is a crucial piece of equipment used to measure the wear resistance of materials commonly used in pet toys and other consumer products. By subjecting materials to controlled friction, this machine simulates the stresses placed on pet toys during repeated use, including chew toys, interactive toys, flying discs, and balls.

This test is essential for evaluating how well materials like eco-friendly foam, rubber, and plastic can withstand everyday wear and tear caused by pet activities. Pet toys are often subject to continuous friction from biting, chewing, and tugging, making it vital to test their durability under conditions that mimic real-world use.

The NBS machine works by using a rotating drum to press against a test material sample, measuring the loss of material, surface wear, and breakdown of the material structure over time. This process helps determine:

• Material abrasion rate and how fast the material breaks down under friction

• Surface durability, including cracking or roughening

• Long-term performance and safety of pet toys, ensuring they remain intact during repetitive use

• Changes in texture or surface smoothness over time

By ensuring that pet toys are abrasion-resistant, this test supports the development of safe, durable, and reliable products that last through daily interaction with pets, helping to prevent the risks of wear-related damage such as choking hazards or broken parts.
