Model NO.: EP200 Material: Rubber Feature: Heat-Resistant, Water-Resistant Erformance Index Standard: Hg/T3647 Elongation at Break: >=450% Application: Long Distance Conveying Bottom Rubber: 0.8-4.5mm Length: <=300m Trademark: OUNA Origin: Tongcheng, China Type: EP400 Inside Material: Polyester Tensile Strength: Strong OEM: Accept Abrasion Loss: 120mm Top Rubber: 2.0-8.0mm Width: 300~2600mm Production Standard: ISO,DIN,Cema,ASTM Specification: ISO, DIN, GB/T, AMS, CEMA, SHA etc HS Code: 40101900 Diamond Mine Conveyor Belt / Gold Mine conveying belt/ Copper Mine conveyor belting

Features:
1. Heating resistant conveyor belt has heat aging and ozone aging,there will not appear premature aging phenomenon of cracks etc.with the conveyor belt;
2. It can be used in natural environment such as sunshine,moisture and cold,and there will take place the cracking phenoenon with it whthin three years under exposure to strong sunshine.

Item index		Between plies	Between rubber and carcass
		N/mm	N/mm
CC/TC	≥ Average value of longitudinal samples	3.2	2.7
	≥  Min. peak value of longitudinal sample	2.7	2.2
NN/EP	≥ Average value of longitudinal samples ≥	4.5	3.5
	≥  Min. peak value of longitudinal sample	3.9	2.9

Features of EP belting:
(1)High bond strength, flexure resistance and good troughability;
(2)Compared with nylon canvas, the dimensional stability and heat resistance are better.
(3)High resistance to water, the strength hardly changes in both dry or wet condition.

Application:
It is suitable for conveying high-load materials in medium and long distance at high speed.
