TS-7404H Ca/Zn Stabilizer for PVC Drainage Pipes

Powder Form · 2.5–3.0 PHR
Non-Lubrication Formulation for Maximum Fusion and Structural Strength

PVC drainage pipes are judged not by shine or speed, but by how well they hold together when everything else pushes back—soil pressure, temperature swings, time itself. TS-7404H is engineered for exactly that environment.

TS-7404H is a calcium-zinc (Ca/Zn) stabilizer in powder form, developed specifically for rigid PVC drainage pipe extrusion where non-lubrication is not a limitation, but a design choice. With a recommended dosage of 2.5–3.0 PHR, it delivers strong thermal stabilization while leaving lubrication fully under the processor’s control.

Why Non-Lubrication Is a Strategic Advantage

In many drainage pipe formulations—especially thick-wall, large-diameter, or high-filler systems—lubrication can become the enemy. Too much slip weakens fusion, reduces impact strength, and causes internal layering that may not be visible… until failure.

TS-7404H contains no built-in lubrication, allowing:

• Maximum PVC fusion

• Strong melt cohesion

• High internal strength

• Precise external lubrication control

This makes TS-7404H ideal for manufacturers who prefer to design lubrication separately, tailoring it exactly to their extrusion line and pipe dimensions.

Powerful Thermal Stabilization

Even without lubrication, heat must be controlled. TS-7404H provides robust Ca/Zn thermal stabilization, protecting PVC from degradation during processing.

Thermal benefits include:

• Strong initial heat stability

• Effective suppression of HCl release

• Protection against discoloration and burning

• Stable performance during long extrusion cycles

This allows processors to maintain firm temperature profiles without risking premature degradation.

Processing Behavior: Firm, Controlled, Predictable

TS-7404H creates a melt that grips the metal, not slides over it. This behavior improves dimensional accuracy and pipe roundness—critical for drainage systems where alignment and joint integrity matter.

Processing advantages:

• Excellent fusion development

• Stable torque behavior

• Predictable die pressure

• Minimal melt slippage

It is especially effective on:

• Thick-wall drainage pipes

• Large-diameter sewer pipes

• High-filler PVC formulations

Mechanical Strength for Infrastructure Use

Drainage pipes stabilized with TS-7404H are built for endurance. The non-lubricated system helps preserve the integrity of the PVC matrix, resulting in pipes with:

• High compressive strength

• Strong impact resistance

• Excellent long-term dimensional stability

• Resistance to thermal aging

This makes TS-7404H well suited for municipal, industrial, and civil engineering drainage applications.

Surface Quality: Functional, Solid, Reliable

Without internal lubrication masking defects, surface quality becomes a true indicator of process stability. TS-7404H supports:

• Clean, uniform pipe surfaces

• Reduced internal layering

• Consistent appearance across production runs

External lubrication can be adjusted precisely to achieve the desired surface finish without compromising structure.

Lead-Free and Regulation-Ready

TS-7404H uses a modern Ca/Zn stabilizing system, completely free from lead and other heavy metals.

Compliance highlights:

• RoHS compliant

• REACH aligned

• Suitable for infrastructure and construction markets

• Safe for long-term drainage applications

Compatibility and Formulation Freedom

TS-7404H integrates easily into rigid PVC formulations and is compatible with:

• Calcium carbonate fillers

• Processing aids

• Impact modifiers

• Pigments and TiO₂

Because it contains no lubrication, it gives formulators maximum freedom to design lubrication systems tailored to their equipment and output goals.

Recommended Use

• Dosage: 2.5–3.0 PHR

• Processing: Extrusion

• Mixing: High-speed mixing recommended

Lubrication should be added separately and adjusted according to pipe size, filler level, and extrusion speed.

Packaging and Storage

• Supplied in moisture-resistant packaging

• Store in cool, dry conditions

• Protect from humidity and direct sunlight

• Follow FIFO inventory management

Why TS-7404H

Because sometimes strength comes from restraint.

TS-7404H offers:

• Non-lubricated formulation for maximum fusion

• Strong Ca/Zn thermal stabilization

• Excellent dimensional control

• High mechanical strength

• Environmental compliance

It is the stabilizer of choice when structural integrity, fusion quality, and long-term reliability outweigh speed or surface gloss.
