PVC Granules for Brake Cables Sheathing

Product Overview

PVC Granules for Brake Cable Sheathing are specially formulated PVC compounds designed for manufacturing protective outer layers of brake cables. With excellent abrasion resistance, temperature stability, and mechanical strength, these granules help produce durable cable sheaths that ensure reliable performance in demanding environments.

Designed for extrusion processing, the material provides consistent melt flow, smooth surface finish, and stable production performance. Its balanced flexibility and strength allow brake cable sheaths to maintain protection and operational reliability under continuous bending, friction, and temperature changes.

Key Features & Advantages

Excellent Abrasion and Wear Resistance

The PVC compound offers strong resistance to abrasion and wear caused by continuous contact with cable guides, housings, and surrounding components, helping extend the service life of brake cables.

Reliable Temperature Performance

With continuous service temperature resistance of ≥80°C and good thermal stability during processing, the material maintains structural integrity under heat generated by friction or operating environments.

Outstanding Low-Temperature Flexibility

The formulation maintains flexibility in cold conditions, with cold bend performance down to ≤ -30°C without cracking, ensuring reliable cable protection in winter environments.

Balanced Strength and Flexibility

With tensile strength ≥15 MPa, elongation ≥300%, and Shore A hardness of 75–85A, the PVC granules provide a balance of durability, flexibility, and resistance to deformation.

Smooth Surface and Low Friction Performance

The low-friction characteristics help reduce resistance between the cable and sheath, supporting smoother operation and improved braking response.

Applications

PVC Granules for Brake Cable Sheathing are mainly used for manufacturing protective cable coverings, including:

Automotive Brake Cables
Provides flexible and durable protection for brake cable systems in vehicles.
Bicycle Brake Cables
Suitable for cable housings requiring smooth operation, flexibility, and wear resistance.
Mechanical Control Cables
Used for protective sheathing in various cable assemblies exposed to bending and friction.

Parameter	Target Value / Range	Importance for Brake Cables
Density	1.35 – 1.45 g/cm³	Affects the weight and material yield of the sheathing. A balance is needed for durability without unnecessary bulk.
Heat Resistance
• Continuous Service Temp	≥ 80°C	Prevents softening and deformation from engine bay heat or friction-generated warmth.
• Thermal Stability (200°C)	≥ 40 mins	Ensures the material doesn’t degrade during high-temperature extrusion processing.
Low-Temperature Resistance
• Cold Bend / Brittleness Temp	≤ -30°C (No Cracks)	Critical. Maintains flexibility in winter conditions, preventing the sheath from becoming brittle and cracking.
Wear & Abrasion Resistance
• Abrasion Resistance (Taber)	≤ 80 mm³ (Volume Loss)	Critical. Protects against wear from constant rubbing against guides, housings, and frames, extending cable life.
• Tear Strength	≥ 18 N/mm	Resists the propagation of nicks or cuts.
Mechanical Properties
• Tensile Strength	≥ 15 MPa	Withstands pulling and stretching forces during installation and use.
• Elongation at Break	≥ 300%	Provides high flexibility and ability to withstand sharp bends without breaking.
• Hardness (Shore A)	75 – 85 A	Offers a balance: firm enough to resist compression and cutting, but soft enough for smooth operation.
Surface & Friction
• Coefficient of Friction	Low	Minimizes friction between the inner cable and the sheath for smooth, responsive braking action.
