Introduction: whole core flame retardant conveyor belt is mainly used in coal mine.

特点：带体不脱层，伸长小，抗冲击，耐撕裂。

Features: no delamination, small elongation, impact resistance and tear resistance.

按结不同可以分为

According to the different knot can be divided into

PVC型（塑料面），

PVC type (plastic surface),

PVG型（在PVC基础上加附橡胶面）整芯阻燃带，执行MT/914-2002标准。

PVG type (with rubber surface on the basis of PVC) whole core flame retardant tape, in accordance with MT / 914-2002 standard.

PVC型适用于16度以下倾角的干燥条件下的物料输送。

PVC type is suitable for material transportation under dry condition with inclination angle below 16 degrees.

PVG型适用于20度以下倾角的潮湿有水物料的输送。

PVG type is suitable for conveying wet and watery materials with inclination angle below 20 degrees.
