Product overview

     DS-4817 is improved based on our original dry strength agent and it adopts the most advanced technology and overseas raw materials.Its amphoteric characteristic make it be attracted to the pulp fibers directly.The formed electrovalent bonds via the ionics bonding can increase the bonding strength of fibers so as to effectively improve the paper dry strength,breaking length,bursting strength,RCT,peel strength and etc.It is widely used in the production of package paper,cultural paper,tissues paper and etc.
