CAS Number: 23877-44-3
Molecular formula : would be something like (–COO– monomer unit)n + (–SO₃– monomer unit)m + associated counterions (e.g. Na⁺) + water of hydration, etc. But the exact monomer ratio (n : m) is proprietary, so one cannot assign a single formula.
Molecular weight / molar mass : likely in the thousands (e.g. ~ 10,000 g/mol or more) depending on chain length and polydispersity — but no reliable public value for TH-5000 itself.

TH-5000 Carboxylate-Sulfonate copolymer is a superior scale inhibitor and dispersant.
TH-5000 Carboxylate-Sulfonate copolymer has good inhibition for silica and magnesium silicate when used in recirculation cooling circuits and boilers.
TH-5000 Carboxylate-Sulfonate copolymer is a modern synthetic water-soluble polymer designed to deliver high performance in aqueous systems where dispersion, stabilization, and deposit control are critical.
TH-5000 Carboxylate-Sulfonate copolymer belongs to the class of anionic copolymers that combine carboxylate and sulfonate functional groups within the same polymer backbone.
This dual-functionality gives TH-5000 Carboxylate-Sulfonate copolymer a strong affinity for metal ions, inorganic particles, and hard-water components, while maintaining excellent solubility and stability over a wide pH and temperature range.
From an introductory perspective, TH-5000 Carboxylate-Sulfonate copolymer is developed as a multifunctional performance additive rather than a single-purpose chemical.
The presence of carboxylate groups provides effective chelation and scale-inhibition capability, especially against calcium, magnesium, and iron salts.
At the same time, sulfonate groups contribute to high anionic charge density, strong electrostatic repulsion, and outstanding dispersing power.
The combination of these two functional groups makes TH-5000 Carboxylate-Sulfonate copolymer particularly effective in preventing particle agglomeration and mineral deposition, even under harsh operating conditions such as high alkalinity, elevated temperature, or high dissolved-solids environments.
Unlike traditional homopolymers, TH-5000 Carboxylate-Sulfonate copolymer is engineered to remain active and stable in complex formulations.
TH-5000 Carboxylate-Sulfonate copolymer shows excellent resistance to hydrolysis and oxidative degradation, which allows it to maintain performance in long-term industrial processes.
TH-5000 Carboxylate-Sulfonate copolymer's molecular architecture is designed to provide controlled molecular weight distribution, ensuring consistent performance, low viscosity impact, and compatibility with other formulation components such as phosphonates, surfactants, biocides, and other polymeric additives.
TH-5000 Carboxylate-Sulfonate copolymer can be described as a versatile, high-efficiency anionic copolymer that integrates dispersion, scale inhibition, and stabilization into a single product.
Its advanced copolymer structure, chemical stability, and compatibility with diverse formulations make TH-5000 Carboxylate-Sulfonate copolymer a valuable component in water treatment, detergents, and various industrial and specialty chemical applications.
USES and APPLICATIONS of TH-5000 CARBOXYLATE-SULFONATE COPOLYMER:
TH-5000 Carboxylate-Sulfonate copolymer is designed for operational robustness rather than narrow chemical specificity.
In industrial water systems, conditions such as hardness, alkalinity, temperature, flow rate, and contamination can change daily.
TH-5000 Carboxylate-Sulfonate copolymer addresses this variability by combining two complementary functional chemistries—carboxylate and sulfonate—within a single polymer chain.
This dual functionality allows TH-5000 Carboxylate-Sulfonate copolymer to maintain performance even when one interaction pathway becomes less effective due to changes in water chemistry.
The carboxylate groups in TH-5000 Carboxylate-Sulfonate copolymer provide controlled interaction with alkaline earth metals such as calcium and magnesium.
These groups interfere with mineral crystal nucleation and growth, particularly calcium carbonate and calcium sulfate scales.
Instead of forming dense, adherent deposits on heat-transfer surfaces, minerals are forced to precipitate as distorted microcrystals that remain dispersed in the bulk water.
This mechanism significantly reduces fouling of heat exchangers and piping, even under high cycles of concentration.
The sulfonate groups play a stabilizing role under harsh conditions.
Unlike carboxylates, sulfonates remain strongly ionized across a wide pH range, including high-alkalinity environments where many traditional acrylic polymers lose efficiency.
This makes TH-5000 Carboxylate-Sulfonate copolymer particularly effective in systems with high pH, high conductivity, or elevated dissolved solids.
Sulfonate functionality also improves calcium tolerance, preventing polymer precipitation or “salting out” when hardness levels increase unexpectedly.
One of the less obvious but highly valuable aspects of TH-5000 Carboxylate-Sulfonate copolymer is its dispersing capability.
Industrial water systems constantly generate fine particulate matter from corrosion, airborne dust, and process contamination.
TH-5000 Carboxylate-Sulfonate copolymer adsorbs onto these particles and imparts electrostatic repulsion, preventing agglomeration and deposition.
This keeps particles suspended long enough to be removed by blowdown, filtration, or separators, rather than allowing them to settle and form insulating layers on metal surfaces.
TH-5000 Carboxylate-Sulfonate copolymer is a superior phosphate scale inhibitor for dry or hydrated ferric oxide.
Acting as rust inhibitor, TH-5000 Carboxylate-Sulfonate copolymer can also be used in systems like industrial RO, pools and fountains etc.
In practical use, TH-5000 Carboxylate-Sulfonate copolymer is widely applied in industrial water treatment systems, including cooling water, boiler water, and reverse-osmosis pretreatment, where it helps control scale formation, disperse suspended solids, and reduce fouling on heat-transfer surfaces and membranes.
TH-5000 Carboxylate-Sulfonate copolymer is also used in detergent and cleaning formulations to prevent soil redeposition and to stabilize inorganic particles during washing processes.
In construction chemicals and specialty formulations, TH-5000 Carboxylate-Sulfonate copolymer functions as a dispersant and stabilizer for mineral fillers, pigments, and cementitious systems, improving flow properties and overall performance.
Another important aspect of TH-5000 Carboxylate-Sulfonate copolymer is its broad formulation flexibility.
TH-5000 Carboxylate-Sulfonate copolymer performs effectively across a wide pH range, typically from mildly acidic to strongly alkaline conditions, and remains soluble in hard water and high-electrolyte environments.
This makes TH-5000 Carboxylate-Sulfonate copolymer suitable for use in modern, phosphate-reduced or phosphate-free systems, where polymer-based performance additives are increasingly required to meet environmental and regulatory expectations.

HOW TH-5000 CARBOXYLATE-SULFONATE COPOLYMER WORKS IN WATER TREATMENT:
TH-5000 Carboxylate-Sulfonate copolymer is engineered to keep water systems running efficiently by preventing two major problems:
Mineral Scale Formation – Hard water contains dissolved minerals (like calcium, magnesium, silica).
When heated or concentrated, these minerals can precipitate and form hard “scale” that sticks to pipes and heat exchangers.
TH-5000 Carboxylate-Sulfonate copolymer molecules adsorb onto forming mineral crystals, interfering with their growth and helping keep them dissolved or in a fine, non-sticking form.
Particulate Dispersion – Industrial water systems often carry corrosion products and suspended solids.
TH-5000 Carboxylate-Sulfonate copolymer’s functional groups help bind with and electrically stabilize these particles, preventing them from clumping and sticking to metal surfaces.
This keeps the solids in suspension so they can be removed or stay harmlessly circulating.
USAGE of TH-5000 CARBOXYLATE-SULFONATE COPOLYMER:
When TH-5000 Carboxylate-Sulfonate copolymer is used alone, the dosage of 15-30mg/L.
When TH-5000 Carboxylate-Sulfonate copolymer is used as dispersant in other fields, the dosage should be determined by experiment.
