Acid/alkali-resistant belt adopt rubber –plastics blending technics and with other inert material which can resist acid and alkali very well, more excellent than neoprene made, this kind of coveyor belt adopt EP canvas as layer, more stable and endurable than cotton canvas in terms of acid/alkal resisting side.
The Acid/alkai-resistant conveyor belt is suitable for acid and alkali working environment such as phosphorus fertilizer site; solar salt process etc.
