Calcium stearate( C₃₆H₇₀CaO₄)

Calcium stearate( C₃₆H₇₀CaO₄) : Price, Uses, Applications & PVC

Calcium Stearate is a widely used industrial additive found in various plastic, PVC and rubber formulations. It is generally available in powder form and is used as part of additive systems where lubrication and processing behaviour are important.

A 1 kg quantity of Calcium Stearate is often considered for laboratory testing, formulation development, product trials and initial material evaluation. However, the price and suitability of the material can vary depending on grade, purity, supplier, packaging and application.

For PVC manufacturers, understanding the role of Calcium Stearate is important before selecting a product or considering an alternative.

What Is Calcium Stearate?

Calcium Stearate is a calcium salt of stearic acid and is commonly supplied as a fine powder.

It is identified by CAS No. 1592-23-0 and is used in different industrial applications because of its lubrication and processing-related characteristics.

The properties and specifications of Calcium Stearate can vary between grades. Therefore, buyers should always check the technical specifications of the particular product they are considering.

Calcium Stearate Uses

Calcium Stearate is used in several industrial applications.

Some common areas include:

PVC processing
Plastic processing
PVC compounds
Rubber formulations
Rigid PVC products
Coatings
Industrial formulations
Processing and release applications

The exact function of Calcium Stearate depends on the formulation and manufacturing process.

Calcium Stearate in PVC Processing

Calcium Stearate is commonly considered as part of the lubricant system in PVC formulations.

During PVC processing, the additive system can influence material flow, friction, processing behaviour and the characteristics of the finished product.

Lubrication

Calcium Stearate can contribute to the lubrication system used during PVC processing.

Processing Behaviour

The right combination of lubricants and processing additives can support controlled material movement through processing equipment.

Surface Finish

The balance of the lubricant system can influence the surface appearance of finished PVC products.

Formulation Performance

Its actual performance depends on the complete formulation, including PVC resin, stabilizers, fillers, lubricants and other additives.

There is no universal Calcium Stearate dosage for every PVC application. The appropriate level should be determined through formulation and production trials.

Applications of Calcium Stearate in PVC

Calcium Stearate can be used in formulations for different rigid PVC products, such as:

PVC Pipes

It may be incorporated into lubricant systems used for PVC pipe processing.

PVC Profiles

Rigid PVC profiles can require carefully balanced lubrication for controlled processing.

PVC Compounds

Calcium Stearate may be used alongside stabilizers, fillers, pigments and other processing additives.

PVC Conduit

It can also be considered in formulations for rigid PVC conduit and similar products.

The required specification depends on the formulation and final application.

Calcium Stearate 1 kg Price in India

There is no single fixed price for Calcium Stearate 1 kg in India.

Supplier quotations can vary depending on:

Grade
Purity
Quantity
Packaging
Supplier
Location
GST
Shipping charges
Minimum order quantity
Technical specifications

Online B2B marketplaces may show different supplier quotations. These should be considered indicative prices, and buyers should confirm the final price and specifications directly with the supplier.

When comparing Calcium Stearate prices, it is better to consider the complete cost and product specification instead of choosing only the lowest quoted price.

Why Buy Calcium Stearate in 1 kg Quantity?

A 1 kg pack can be useful when a manufacturer or R&D team wants to test a material before moving to larger quantities.

Typical reasons include:

Laboratory evaluation
R&D testing
PVC formulation trials
Product development
Material comparison
Initial supplier evaluation
Small-scale testing

Once the material has been evaluated successfully, manufacturers can consider bulk procurement based on their production requirements.

Why Do PVC Manufacturers Consider Calcium Stearate Alternatives?

Calcium Stearate can work effectively in many formulations, but PVC manufacturers may sometimes evaluate alternative additive solutions based on their specific requirements.

The reasons for evaluating an alternative can include:

Formulation optimisation
Processing requirements
Additive consumption
Cost considerations
Lubrication behaviour
Production consistency
Surface finish requirements

The important point is that an alternative should not be selected only by comparing price per kg.

A proper evaluation should consider the overall formulation and production performance.

CS Ultra™ – Calcium Stearate Replacement for PVC

After understanding Calcium Stearate and its role in PVC processing, manufacturers can evaluate alternative solutions according to their specific requirements.

CS Ultra™ is positioned as a Calcium Stearate replacement for suitable PVC processing applications.

It can be evaluated against an existing Calcium Stearate formulation based on parameters such as:

Processing behaviour
Lubrication performance
Dispersion
Surface finish
Processing stability
Dosage requirement
Additive cost
Production consistency

The actual suitability of CS Ultra™ depends on the specific PVC formulation and processing conditions. Therefore, a laboratory or controlled production trial is recommended before making a complete formulation change.

Calcium Stearate vs CS Ultra™: What Should Manufacturers Compare?

Instead of looking only at the purchase price, manufacturers can compare both solutions based on their actual production requirements.

Feature	Calcium Stearate(CS)	CS Ultra™
Price	Regular Price	Cheaper Price
Application	PVC Processing, PP Compounds, Cable Compounds, Rubber Processing,Other Applications	Only PVC Processing
Lubrication	Standard	Better Lubrication
Dispersion	Standard	Better Dispersion
Surface Finish	Standard	Better Smoother Finish
Formulation	Standard Formulation	100% Replacement

Note: Actual performance should be established through application-specific trials rather than assumed from a general comparison.
