Zeolite 4A grade Detergent
It is a white powder, non-toxic, odorless and good fluidity. With strong power of Calcium exchange and compatibility and without pollution, the product is ideal phosphate-free addition that substitutes for STPP (Sodium Tripolyphosphate) as a detergent builder. It is used widely in detergent Industry.

Synthetic detergent zeolites, are the principle alternative to phosphate type builders, used in household detergents and softening the washing water by calcium ion exchange.

The major part of phosphate-free household detergents is based on the use of Zeolite 4A as builder.

As a detergent builder, Zeolite A was developed specifically as an environmentally preferable alternative to phosphate builders, which can cause eutrophication of freshwater bodies by nourishing excessive amounts of algae.

Zeolites possess a number of advantages over other builders during the production of detergents. With regards, zeolites display a very high product stability, regardless of the particular process employed (spray drying, granulation, extrusion etc). They prove inert when exposed to elevated temperatures, mechanical influences or alkalinity.

The high flexibility of zeolites with respect to formulation and ease of processing together with the economic advantage of the raw material have led to it becoming an extremely attractive builder.

  • It is used for deep drying of air, natural gas, alkane and refrigerant.
  • It is used for generation and purification of argon
  • It is also used for static dehydration of electronic element, pharmaceutical and unstable materials.
  • It is widely used as Desiccant for paint, dope and foul etc.
  • Type 4A molecular sieve is typically used in regenerable drying systems to remove water vapor or contaminants which have a smaller critical diameter than four angstroms.
