Tianshi Nano: A century of craftsmanship, building a leading brand in nano calcium carbonate

On the banks of the Xin'an River in Jiande, Zhejiang, an enterprise that has weathered nearly two centuries of storms is leading China's calcium carbonate industry toward high-end and green development through innovation-driven strategies. This is Zhejiang Tianshi Nano-Tech Co., Ltd.—a national high-tech enterprise and a national "Little Giant" enterprise specializing in "specialized, refined, distinctive, and innovative" (SRDI) fields, integrating research, production, and sales.

From Traditional Lime to Nano Technology: A Century-Long Leap of an Enterprise

Zhejiang Tianshi Nano-Tech Co., Ltd. was founded during the Xianfeng era of the Qing Dynasty. From initially producing quick lime for agriculture and construction, the company has now developed the capability to produce food-grade and industrial-grade calcium carbonate, calcium hydroxide, calcium oxide, and active nano calcium carbonate, marking an extraordinary journey of development.

The company was officially registered in 1997 and successfully listed on the "NEEQ" (New Third Board) in 2016 (Stock Code: 837392.NQ), becoming the first listed enterprise in the industry on this board. Today, the company covers an area of over 200 mu, employs more than 260 staff, and boasts a professional technical team composed of Ph.D. holders, senior engineers, and industry application experts. It has also established a provincial-level R&D center for specialty calcium carbonate.

With profound technical accumulation, Tianshi Nano is now a core member of the China Calcium Carbonate Collaboration Group and the leader of the Calcium Carbonate Working Group of the Inorganic Chemicals Branch of the National Chemical Standardization Technical Committee. It has participated in the formulation and revision of over 20 national industry standards and obtained more than 50 patents.

Flagship Products: Diversified Layout Covering High-End Application Scenarios

Tianshi Nano possesses seven automated production lines for different products with a design capacity of 300,000 tons, and has formed a production capacity of nearly 200,000 tons of series products per year. Its core product matrix is rich, meeting the needs of various industries:

-Calcium Carbonate Series Products

Nano Calcium Carbonate: The company independently broke through technical bottlenecks and successfully achieved import substitution, widely used in sealants, rubber and plastic materials, and building materials.

Light Calcium Carbonate: Including light calcium carbonate for toothpaste and specialty calcium for cigarette paper (tipping paper).

Food Additive Calcium Carbonate: Possessing a food production license and dedicated production workshops, serving the food industry.

-Extended Calcium Products

High-end Calcium Hydroxide, High-end Calcium Oxide Series

-Functional Modified Materials

PVC Nano Stiffening and Toughening Modifier: Effectively solves the toughening challenges of traditional modifiers in low-temperature brittleness and high-filling systems.

Reinforcing and Toughening Masterbatch for Heavy Packaging Films like PE: Can significantly reduce the addition of petrochemical resins and lower production costs.

Nano Calcium Prepolymer (NPCC-PDMS-GCC ternary composite prepolymer), suitable for high-end industrial adhesive production such as photovoltaic modules and electronic/electrical component encapsulation.

Core Advantages: Three Pillars of Technology, Brand, and Customers

1. Profound Technical Accumulation and Innovation Capability

The company possesses a provincial-level R&D center for specialty calcium carbonate and holds nearly 30 national invention and utility model patents. Its independently developed nano calcium carbonate production technology has broken foreign monopolies and effectively reduced production costs for domestic enterprises. In recent years, the company has continuously increased investment in technical transformation, with projects such as food calcium capacity and quality improvement and nano calcium production line upgrades amounting to tens of millions of yuan.

2. Market Recognition of Famous Brands like "Triangle Brand"

The company's "Triangle Brand" series products and "Rigao" brand active nano calcium carbonate enjoy excellent performance, reliable quality, and a high reputation in the industry. The products are widely used in toothpaste, food, pharmaceuticals, rubber, plastics, papermaking, construction sealants, and rubber/plastic materials.

3. Stable Customer Base of Globally Renowned Companies
