Introduction to Truck Brake Linings Organic Mixture
Truck brake linings organic mixtures are eco-friendly brake linings friction materials designed for medium-duty braking applications. Composed of non-asbestos organic fibers (e.g., glass, Kevlar, rubber), resin binders, and friction modifiers, this brake linings formula prioritizes low noise, smooth engagement, and environmental sustainability. Below is a detailed overview of its technical specifications, advantages, and storage protocols, supported by industry benchmarks from Alibaba suppliers.
Technical Parameters
The table below summarizes the key properties of organic-based brake linings mixes:
| Parameter | Specification | Remarks |
|---|---|---|
| Organic Fiber Content | 40-60% (Kevlar, glass, cellulose) | Reduces wear and noise |
| Density | 2.0-2.5 g/cm³ | Lightweight design for reduced inertia |
| Friction Coefficient (μ) | 0.30-0.40 (Dry) | Smooth braking at low to medium speeds |
| Operating Temperature | -30°C to 300°C | Suitable for urban and highway use |
| Compressive Strength | ≥150 MPa | Adequate for standard hydraulic systems |
| Wear Rate | ≤0.8 cm³/MJ | Balanced longevity and cost efficiency |
| Shore Hardness | 50-65 Shore D | Optimized for minimal drum scoring |
Key Advantages
- Low Noise and Vibration
The brake linings mixture incorporates rubber and cellulose fibers to dampen vibrations, making it ideal for noise-sensitive environments like urban logistics. - Eco-Friendly Composition
Free from asbestos and heavy metals, aligning with global environmental regulations. - Cost-Effective Performance
Lower production costs compared to metallic or ceramic alternatives, suitable for budget-conscious fleets. - Rapid Bed-In Period
Organic brake linings friction materials achieve optimal friction efficiency faster than semi-metallic counterparts, reducing downtime. - Compatibility with Standard Drums
Works seamlessly with cast iron drums, minimizing retrofitting requirements.
Storage and Packaging
- Moisture Protection: Packaged in vacuum-sealed, moisture-proof bags to prevent resin degradation.
- Temperature Limits: Store in dry environments below 35°C; avoid freezing temperatures to maintain fiber integrity.
- Stacking Guidelines: Maximum 8 layers to prevent deformation of the friction layer.
- Shelf Life: 18 months in unopened, original packaging.
Application of Brake Linings Mixes
The brake linings formula is molded under moderate pressure (10-20 MPa) and cured at 150-200°C to ensure adhesion to the brake shoe plate. Post-production testing includes shear strength (≥2.5 MPa) and thermal cycling resilience to validate performance under repetitive stress.
For specialized requirements, manufacturers like Feelparkins Auto Parts adjust fiber-to-resin ratios in the brake linings mixes to meet OEM specifications, such as enhanced heat dissipation or extended wear resistance .
This organic mixture strikes a balance between performance, sustainability, and affordability, making it a preferred choice for commercial vehicles operating in regulated or noise-sensitive zones.
