Quick Details
Specifications
Construction:
This product is made by adopting solid belt cord as the carcass material and plasticizing PVC material with excellent antistatic and
flame resistant property through impregnation and coating.
Features:
(1) Good elasticity and impact-proof; small elongation at fixed load, suitable for long-distance conveying;
(2) High safety performance, can guarantee safe and high-efficiency operation of conveying system;
(3) Thin belt body, light weight and good troughability;
(4) Tear-resistant and good resistance to flexure.
Application:
It is used for material conveying in mining downholes and other applications where flame retardance and resistance to static
electricity are required.
