Applications and Performance Characteristics of Rubber

1. Application Scenarios

Automotive Field:

Suitable for drum brake systems, such as the parking brakes of passenger cars and commercial vehicles, as well as the low drag torque design of new energy vehicles.

Industrial Machinery:

Applicable to equipment requiring high-load braking, including ship windlasses, mine hoists, and cranes. These devices demand brake bands with impact resistance and high-temperature resistance.

Rail Transit:

Used for auxiliary braking of subways and trams, featuring the advantages of low noise and low track wear.

2. Performance Characteristics

Friction Performance:

The friction coefficient of asbestos-free rubber brake bands is stable (ranging from 0.34 to 0.39). They perform excellently on both dry and wet road surfaces and have a fast emergency braking response.

Temperature Resistance:

Ordinary models can withstand a temperature of approximately 300℃.

High-end products (such as Brembo ceramic pads) can resist high temperatures up to 800℃, making them suitable for racing tracks or heavy-load scenarios.

Durability:

Products with a special formula have a low wear rate, and their service life is extended by more than 30% compared with traditional asbestos brake bands.
