Ca/Zn Stabilizer for PVC Large Fittings – TS-6109A

High-Grade Stabilization for High-Pressure Water Fittings (OD ≥ 200 mm)

Large-diameter, high-pressure PVC fittings live a hard life. Thick walls mean longer heat exposure. High internal pressure demands molecular integrity. Any weakness in stabilization shows up early — discoloration, brittleness, stress cracking, or long-term failure in the field.

TS-6109A is a high-grade calcium/zinc stabilizer, engineered specifically for large PVC fittings with outer diameters ≥ 200 mm, used in high-pressure water systems. It is designed to protect PVC through extended processing cycles while preserving the mechanical strength required for pressure-rated components.

This stabilizer is not tuned for thin parts or general fittings. It is purpose-built for massive, structural PVC componentswhere thermal load, pressure resistance, and dimensional stability must align perfectly.

Engineered for High-Pressure, Large-Diameter Applications

High-pressure water fittings introduce extreme processing conditions:

• Long residence time in extrusion or molding

• High melt temperatures

• Thick cross-sections requiring deep stabilization

• Strict pressure and leakage standards

TS-6109A addresses these challenges with a low-filling, high-purity formulation, ensuring that active stabilizing components penetrate and protect the entire wall thickness — not just the surface.

It is ideal for:

• Large PVC pressure fittings

• Water supply flanges

• High-pressure valves and valve bodies

• Large couplings, reducers, and adapters

• Infrastructure fittings for municipal water networks

High-Grade, Low-Filling Formulation

When fittings get larger, inert fillers become liabilities. TS-6109A avoids that trap.

Its low-filling formulation delivers:

• Higher active stabilizer concentration

• Stronger heat protection per PHR

• Improved fusion consistency

• Better mechanical property retention

This makes TS-6109A especially suitable for pressure-rated fittings, where material purity and performance outweigh marginal cost reductions.

Optimized Dosage for Thick-Wall Stability

Recommended dosage: 5.5 – 6.5 PHR

This range is calibrated for:

• Extended thermal exposure during processing

• Large OD fittings with thick walls

• High internal pressure requirements

At this dosage, TS-6109A provides:

• Excellent initial color

• Outstanding long-term heat stability

• Uniform stabilization throughout the fitting

• Reduced risk of internal degradation or brittleness

Mechanical Strength You Can Trust

High-pressure fittings must resist:

• Internal water pressure

• Thermal cycling

• Long-term mechanical stress

TS-6109A supports:

• High impact strength

• Retention of tensile and hoop strength

• Dimensional stability under pressure

• Long service life in water distribution systems

This makes it a reliable choice for municipal, industrial, and infrastructure water networks.

Clean Processing, Reliable Production

Despite its high stabilization power, TS-6109A maintains clean processing behavior, helping manufacturers achieve:

• Low plate-out on screws and molds

• Stable melt flow

• Smooth surface finish on large fittings

• Reduced downtime for cleaning

The result is consistent production of high-quality large fittings, even under demanding conditions.

Environmental and Regulatory Confidence

TS-6109A is aligned with modern environmental and regulatory requirements:

• Lead-free

• Heavy-metal free

• RoHS compliant

• REACH compliant

It supports manufacturers producing safe, export-ready components for global water infrastructure projects.
