What materials and construction make this belt more durable?

• Aramid fiber cords for strong tensile performance and reduced stretching.
• Thick Chloroprene rubber resists oil, heat and wear.
• Two-layer wrap cloth minimizes surface abrasion and improves pulley grip.
• High-adhesion bonding glue to reduce slippage on pulleys.
