TABLE 1
YD LIONTM EP conveyor belts/ PN conveyor belts
"EP"/"PN" is the cacass for reinforcing the conveyor belts, utilizing a polyester fiber for warp
and nylon fibre for weft, and has the following specific features:
1) Less stretch of belt, and high resistance to tension.
2) Greater resistance to moisture, mildew and rot.
3) Less influence under temperature.
4) Excellent toughness.
5) Excellent resistance to impact.
6) Very good resistance to chemicals.
 
YD LIONTM PP conveyor belts/ NN conveyor belts
"PP"/"NN" is the cacass for reinforcing the conveyor belts, utilizing Nylon for warp
and weft, and has the following specific features:
"NN" Refers to nylon warp (along the belt) and nylon weft
(across the belt) cross woven fabric reinforcing. The main
characteristics of nylon/nylon reinforcing are:
1) Exceptional shock and impact resistance to the carrying surface.
2) Superior fastner holding ability.
3) Excellent troughability and flexibility.
4) Greatest resistance to water and mildew.
5) High strength.
