Heat resistant conveyor belt

Introduction
1.It can bear 250 high temperature for a short time
2.It suitable for use in cement,metallurgical and steel industry
The belt carcass of this product is EP fabric of high modulus,low shrink,and high breaking tensile strength.Cover rubber of this product uses EPDM rubber or Chloro-butyl rubber that has very good high temperature resistance.the belt is made with extra care after mixing rubber with high temperature resistant materials,assembling and vulcanizing.
The carcass of this product has very high adhesion after the special treatment of coating and shaping.Under normal working temperature of below 180°C,the belt is low in elongation,excellent in anti-abrasion,and can bear 250°C high temperature for a short time.The belt is suitable foe use in cement, metallurgical and steel industry.
HG2297-92 standard
T1:Could be resistant less than 100℃ test temperature.
T2:Could be resistant less than 125℃ test temperature.
T3:Could be resistant less than 150℃ test temperature.
