Changshu Hongyu Calcium Co., Ltd. will exhibit at ICIF China 2026 from September 15–17, 2026, at the Shanghai New International Expo Centre (SNIEC). Visit us at Booth E6K07 to explore calcium hydroxide, calcium oxide and calcium carbonate solutions for chemical manufacturing and other industrial applications.
As a calcium compound manufacturer established in 1984, Hongyu Calcium has focused on the production and development of calcium oxide, calcium hydroxide and calcium carbonate for more than four decades.
At ICIF China 2026, we look forward to meeting chemical manufacturers, distributors, procurement teams and industry partners from China and overseas.
This year, one of our key focuses will be high-purity calcium hydroxide for chemical manufacturing, particularly grades used in the production of calcium hypochlorite and calcium stearate.
Exhibition: The 23rd China International Chemical Industry Fair – ICIF China 2026
Date: September 15–17, 2026
Venue: Shanghai New International Expo Centre, Shanghai, China

ICIF China brings together companies from across the chemical industry, covering areas including basic chemicals, fine chemicals, new chemical materials, chemical engineering and equipment, environmental protection, packaging, laboratory equipment and related technologies.
For Hongyu Calcium, the exhibition provides an opportunity to communicate directly with downstream manufacturers and better understand the raw-material specifications required by different chemical processes.
Calcium hydroxide is an important raw material used in the manufacture of calcium hypochlorite.
For this type of chemical production, calcium hydroxide should not be evaluated only by its Ca(OH)₂ content. Manufacturers may also need to consider characteristics such as:
calcium hydroxide purity;
available calcium content;
iron and other impurities;
calcium carbonate content;
moisture;
fineness and particle characteristics;
whiteness;
material consistency between batches.
Hongyu Calcium produces calcium hydroxide grades with high purity, low impurity levels and fine particle size, providing options for different chemical manufacturing requirements.
At ICIF China 2026, customers producing calcium hypochlorite are welcome to discuss their existing specifications, production requirements and raw-material concerns with our team.
Another key application we will highlight at the exhibition is calcium hydroxide for calcium stearate production.
Calcium stearate is widely used in plastics, rubber, coatings and other industrial applications. Its manufacturing process places particular importance on the consistency and quality of the calcium-containing raw material.
Depending on the production route and finished-product requirements, manufacturers may evaluate calcium hydroxide according to factors such as:
Ca(OH)₂ content;
purity;
whiteness;
fineness;
impurity profile;
reaction consistency;
batch-to-batch stability.
Hongyu Calcium can provide calcium hydroxide products with different purity and fineness specifications to support a range of industrial chemical applications.
Visitors looking for a calcium hydroxide supplier for calcium stearate manufacturing are invited to bring their target specifications or purchasing requirements to Booth E6K07 for further discussion.
In addition to calcium hydroxide, Hongyu Calcium manufactures three major series of calcium-based materials.
Our calcium oxide products are available with approximately 90–99% CaO content, with options focused on high content, high activity and fine particle size.
Calcium oxide is widely used in chemical processing, environmental applications, construction materials, agriculture and other industrial processes.
View About Calcium Oxide Products→
Our calcium hydroxide range covers approximately 90–99.5% Ca(OH)₂ content, with high-purity, high-whiteness and fine-particle options available for different applications.
Besides calcium hypochlorite and calcium stearate manufacturing, calcium hydroxide is also used across environmental treatment, chemical processing, agriculture and other industries.

Hongyu Calcium also supplies calcium carbonate products with approximately 95–98% calcium carbonate content, featuring high content, high whiteness and fine particle size options.
Together, these product lines allow us to serve customers with different requirements across the calcium compound supply chain.
View About Calcium Carbonate Products→
Changshu Hongyu Calcium Co., Ltd. was established in 1984 and has continuously focused on calcium-based materials.
Today, our production covers calcium oxide, calcium hydroxide and calcium carbonate, with a daily production capacity of approximately 600 tons.
Through long-term production experience, process development and quality control, we have built a product portfolio serving industries including:
chemical manufacturing;
environmental protection;
agriculture;
construction;
industrial processing.
Our calcium products are supplied not only in China but also to customers in markets including Southeast Asia, the Middle East and Africa.
Raw-material resources and upstream quality control are important foundations for stable calcium compound production.
Hongyu Calcium has its own mineral resources in Hubei Province, helping support our long-term calcium product manufacturing capabilities.
In 2024, we further expanded our production capabilities through the establishment of Calison New Materials (Jingshan) Co., Ltd., a new company covering approximately 40,000 square meters.
The new operation focuses on calcium oxide and calcium hydroxide products for applications with more demanding quality requirements, including fine chemicals, pharmaceutical-related applications and food-grade applications.
This expansion strengthens our ability to serve customers requiring more specialized calcium compound specifications.
For chemical manufacturers, selecting calcium hydroxide is ultimately an application-specific decision.
A specification suitable for general environmental treatment may not necessarily be appropriate for calcium hypochlorite production, calcium stearate manufacturing or another fine-chemical process.
At ICIF China 2026, our team is ready to discuss questions such as:
What calcium hydroxide purity does your process require?
Which impurities need tighter control?
What fineness is suitable for your reaction system?
Are whiteness requirements important for the finished product?
What specification are you currently purchasing?
Do you require customized calcium hydroxide parameters?
What packaging and supply volumes are needed for regular production?
Providing this information allows us to recommend a calcium hydroxide grade based on the actual application rather than treating hydrated lime as a single standard commodity.
From September 15–17, 2026, Hongyu Calcium will be waiting for you at the Shanghai New International Expo Centre.
If your business is involved in calcium hypochlorite, calcium stearate, fine chemicals, environmental treatment or other calcium-based industrial applications, we welcome you to visit our team and discuss your raw-material requirements.
