Polyester conveyor belts,also called betway体育app_betway必威网站|唯一首页s,whose tension resistant body is canvas woven by polyester in warp and polyamide in weft.The belts have the characteristics of low elongation in warp and good troughability in weft,good water resistance,good wet strength,no mould,suitable for medium,long-distance and heavy-load transportation of materials.Because of the high initial modulus of polyester,the belts can choose a relative low safety factor.
