Ca/Zn Stabilizer for UPVC Large Fittings – TS-6101

High-Grade Stabilization for Thick-Wall and Structural PVC Components

When PVC moves from thin profiles to large fittings, the rules change. Melt residence time stretches. Heat exposure deepens. Any weakness in stabilization shows up fast — yellowing, brittleness, surface defects, or failed pressure tests.

TS-6101 is a high-grade calcium/zinc stabilizer, specifically formulated for UPVC large fittings and PVC-O large fittings, where material mass demands absolute thermal control and mechanical reliability.

This is not a general-purpose stabilizer.
It is engineered for flanges, valves, couplings, adapters, and oversized molded or extruded fittings that must perform under stress — during processing and throughout their service life.

Designed for Large, Thick, and Demanding PVC Parts

Large fittings create a unique processing environment:

• Longer heating cycles

• Higher internal temperatures

• Increased shear stress

• Greater risk of degradation in the core material

TS-6101 answers these challenges with a low-filling, high-purity formulation, ensuring that stabilization performance is not diluted by excessive inert content.

This makes it ideal for:

• UPVC large fittings

• Pressure-rated flanges

• Valves and valve bodies

• Thick-wall couplings

• Large-diameter PVC-O fittings

High-Grade, Low-Filling Formulation

The philosophy behind TS-6101 is simple:
When the part is large, the stabilizer must work harder — not heavier.

With a low filling formulation, TS-6101 delivers:

• Higher active stabilizer content

• Stronger heat stabilization per PHR

• Cleaner melt behavior

• Improved mechanical property retention

This approach is essential for fittings where strength, dimensional accuracy, and long-term reliability matter more than marginal raw material savings.

Optimized Dosage for Structural Stability

Recommended Dosage: 5.5 – 6.5 PHR

This higher dosage range reflects the reality of large fittings:

• Extended melt residence time

• Greater thermal load during molding or extrusion

• Increased wall thickness requiring deep stabilization

At this dosage, TS-6101 provides:

• Excellent initial color

• Strong resistance to thermal degradation

• Uniform stabilization throughout the cross-section

• Reduced risk of internal brittleness or stress cracking

Excellent Performance in PVC-O Large Fittings

PVC-O fittings introduce an additional layer of complexity. Orientation processes demand exceptional molecular integrity and thermal stability before and during orientation.

TS-6101 supports PVC-O processing by:

• Protecting PVC chains prior to orientation

• Maintaining material integrity under heat and pressure

• Supporting consistent mechanical performance in oriented structures

This makes it suitable not only for conventional UPVC fittings, but also for high-performance PVC-O systems used in pressure and infrastructure applications.

Processing Advantages

From the factory floor perspective, TS-6101 delivers:

• Stable fusion behavior

• Low plate-out tendency

• Clean tooling and molds

• Consistent surface finish on large parts

These benefits translate into:

• Fewer rejected fittings

• Reduced mold cleaning frequency

• Improved production efficiency for large components

Mechanical Integrity That Lasts

Large fittings are structural components. They carry load, pressure, and long-term stress.

TS-6101 helps ensure:

• High impact resistance

• Retention of tensile strength

• Long-term durability under pressure

• Reduced risk of premature failure

This makes it suitable for industrial piping systems, municipal infrastructure, and pressure-rated applications.

Environmental and Regulatory Compliance

TS-6101 is fully aligned with modern regulatory expectations:

• Lead-free

• Heavy-metal free

• RoHS compliant

• REACH compliant

It supports manufacturers transitioning away from legacy lead systems without sacrificing performance in demanding applications.

Typical Applications

• UPVC flanges

• PVC valves and valve bodies

• Large-diameter fittings

• Thick-wall couplings and adapters

• Industrial PVC fittings

• Large PVC-O fittings for pressure systems
