Industry Applications:

1. STPP for Detergent Manufacturing (High-Performance Builder)

 

Unique Selling Points:

• -Optimized for heavy-duty laundry powders & dishwashing detergents

• -Reduces water hardness effectively (Ca²⁺/Mg²⁺sequestration)

• -5% moisture control formula prevents caking
     Technical Edge:
     "Pre-tested compatibility with common surfactants (LAS, AES)"
      Packaging: 25kg bags with anti-moisture double-lining
   

1. 2. STPP for Industrial Water Treatment (Corrosion Inhibitor)

    

    Specialization:

2. --Low-fluoride formula (<0.002%) for cooling tower systems

3. --Synergistic blend with HEDP for scale prevention
     Application Data:
     Dosage: 3-15 ppm (adjust based on water hardness)
     Certification: NSF/ANSI Standard 60 (available on request)
    

   3. STPP Alternative: Sodium Hexametaphosphate (SHMP)

    

    Comparative Advantage:
   --Better dispersion power for ceramic glazes
   --Preferred in paint & coating industries 
   
   Side-by-Specs:

   Parameter	STPP	SHMP
