Question 1

What molar ratios of Sodium Silicate are manufactured by H.S.A?

Accepted Answer

Hindustan Silicates & Aluminates (H.S.A) manufactures custom and standard sodium silicate grades ranging from alkaline ratios of 2.0 to 2.4 (SiO2:Na2O molar ratio) up to neutral ratios of 3.2 to 3.4. Our liquid sodium silicate solutions are produced with specific gravity (Baumé) calibrated between 40°Bé and 60°Bé to meet exacting requirements for soaps, detergents, adhesives, and textile processing.

Question 2

What is the difference between solid sodium silicate glass cullet and liquid sodium silicate?

Accepted Answer

Solid sodium silicate (glass cullet or lumps) is produced directly from rotary fusion furnaces at temperatures exceeding 1400°C by fusing pure quartz silica sand and soda ash. It is formulated for export and bulk distribution. Liquid sodium silicate is created by dissolving solid cullet in high-pressure hydrothermal autoclaves with steam, yielding clear or hazy solutions ready for immediate batch manufacturing in soaps, water treatment, and corrugated box bonding.

Question 3

How does Alumina Hydroxide (ATH) function as an eco-friendly flame retardant?

Accepted Answer

Alumina Hydroxide (Alumina Trihydrate / ATH - HSA-AH01) is a 100% halogen-free, non-toxic flame retardant and smoke suppressant filler. When heated to approximately 200°C, it endothermically decomposes, absorbing approximately 1,050 kJ/kg of heat and releasing 34.6% of its weight as water vapor to cool polymer matrices and dilute combustible gases, while forming a protective ceramic alumina (Al2O3) char layer.

Question 4

What industrial packaging options are available for domestic and international orders?

Accepted Answer

We provide diverse heavy-duty industrial packaging options: 50 KG multi-wall moisture-barrier HDPE-lined woven sacks, 1.0 to 1.25 Metric Ton Type-B and Type-C anti-static FIBC jumbo bags for safe bulk powder discharge, 250 KG sealed virgin HDPE drums for liquid formulations, and dedicated bulk ISO tank containers or road tankers for domestic bulk delivery.

Question 5

What is H.S.A’s minimum order quantity (MOQ) and delivery turnaround time?

Accepted Answer

Our minimum order quantity for standard grades is 1 Metric Ton (or 1 pallet/drum lot) for domestic delivery and 1 Full Container Load (FCL, approx. 20-25 MT) for sea export. Through our Operational State Presence (OSP) across Gujarat, Maharashtra, Rajasthan, MP, Odisha, and Tamil Nadu, domestic dispatches typically arrive within 24 to 48 hours, while international shipments depart within 7 to 10 days from Kandla, Mundra, or Vizag ports.
