Weigh 10g of sodium chloride. Pour it into a graduated cylinder or volumetric flask containing about 80ml of water. Once the sodium chloride has dissolved completely (swirl the flask gently if necessary), add water to bring the volume up to the
Its high-density polyethylene resin has a molecular weight range of 3 to 6 million, compared to 300,000 to 500,000 for high molecular weight (HMW) resins. That difference is what ensures that this material is strong enough to withstand abrasion

Aluminium chloride (AlCl 3), also known as aluminium trichloride, describe compounds with the formula AlCl 3 (H 2 O) n (n = 0 or 6). They consist of aluminium and chlorine atoms in a 1:3 ratio, and one form also contains six waters of
- Why did polyaluminium chloride prices fall 10% in India?
- In the Indian market, however, the average price of HCL fell by 10% due to adequate stock availability and lower demand from the downstream sector. Polyaluminium chloride prices in Asian markets were directly influenced by this price fluctuation.
- What is the size of the poly aluminum chloride market?
- The Poly Aluminum Chloride market size was USD 1.1 billion in 2025 and will grow at a CAGR of 7.8% from 2021 to 2027. The market size refers to USD. Poly aluminum chloride is widely used as flocculant in wastewater treatment, in producing deodorant, antiperspirants and several other end-use.
- Why did polyaluminium chloride prices decline in 2025?
- In North America, the prices of polyaluminium chloride experienced a decline in the first two quarters of 2025 due to diminishing feedstock prices. The chlorine market faced challenges with low demand and surplus supply.
- Why did polyaluminium chloride prices rise in Q1 2021?
- Due to a persistent lack of feedstock chemicals and interrupted production activity, polyaluminium chloride prices rose dramatically across the region. Multiple hurricanes had already caused a severe shortage of HCl in Q4 2025, but devastating winter storms halted all manufacturing efforts again in Q1 2021.
