Feature
Extended Splice Life – Improves durability of steel cord belt splices.
Wear & Tear Resistance – Enhances protection at splice joints.
Contamination Prevention – Double-sided poly film prevents surface contamination.
Compatibility – Works with NR , IR, SBR, and BR rubber grades.
Advantages:
High Abrasion Resistance:
The main protective layer, the cover rubber absorbs impacts and resists abrasion from coal, ore, and other bulk materials. Premium compounds match or exceed the original belt cover’s hardness and durability.
Impact Absorption:
Effectively disperses shock from falling or large-sized material, shielding the tie gum and carcass from damage.
Environmental Sealing:
Creates a dense, continuous shield against moisture, dust, oils, and chemicals (including sulfur in coal), preventing corrosion and degradation of internal layers—especially critical for steel-cord belts.
Optimized Running Surface:
Provides a smooth, low-friction surface for efficient operation, minimizing material buildup and improving belt cleaning.
Tie Gum Protection:
Completely encapsulates the tie gum, ensuring internal adhesion layers are not exposed to harsh environments.
Physical Characteristics: Emphasizes wear resistance, impact absorption, weathering and chemical resistance, and surface finish.
