Lead-Free PVC Powder Stabilizer N-450 — For Transparent Semi-Rigid & Flexible Sheets/Films

Welcome to our WANSYN– Your Trusted Partner for Superior PVC Solutions!

Innovation is always at the core of everything we do. Our expert team of chemists and engineers continuously develops new and advanced stabilizer formulations that meet the evolving needs of the PVC industry. We are dedicated to environmental responsibility, offering eco-friendly stabilizers, PVC know-how services and formulation design that comply with the strictest regulations.

We are your one-stop solution for top-notch PVC stabilizers.

N-450 is a next-generation powder stabilizer for high-clarity transparent PVC in both semi-rigid and flexible applications. It is designed to replace organotin/methyl-tin systems and avoid the environmental risks of liquid stabilizers, while improving cost efficiency. Suitable for calendered sheet/film, extrusion, and blown-film lines.

Key Benefits

Ultra-clear transparency, low/odorless processing

Excellent initial & long-term heat stability; no blooming/plate-out

No heavy-metal residues; RoHS-oriented formulation

Smooth plastication & flow; clean die lips; good printing adhesion

Helps reduce overall processing cost vs. conventional organotin

Typical Properties (reference values)

Appearance: white powder (spec: light-yellow/white powder)

Melting range: 80–150 °C (GB 617-88)

Moisture: ≤ 2.0 % (GB/T 1034-1998) → 0.16 % (typ.)

Loss on heating: ≤ 2.5 % (ASTM D6980-09) → 0.55 % (typ.)

Restricted Substances (RoHS Screening)

PBBs/PBDEs: limit 1000 ppm — ND (GC-MS)

Bisphenol A / Phenol: method limit 10 — ND
Full test reports & compliance statements are available on request.

Recommended Use

Start from your current stabilizer dosage and validate on line; for organotin replacement, optimize phr and balance internal/external lubrication to keep a flat torque curve and preserve high clarity. Confirm surface treatment and ink system when printing.

Typical Applications

Transparent semi-rigid PVC sheets & films (calendered)

Flexible PVC clear films, hoses, sleeves, protective covers

Extruded and blown-film transparent products

Scope of Application:

Powder Calcium-Zinc (Ca-Zn) PVC Stabilizer

Lead-free performance for modern PVC processing.
Our powder Calcium-Zinc (Ca-Zn) stabilizers deliver thermal stability and clean processing without the heavy metals found in legacy systems. Formulated with sustainability in mind, they support high output, consistent color, and durable end-use properties across a wide range of PVC applications.

Why Choose Ca-Zn Stabilizers

Heavy-metal free: No lead, cadmium, barium, or organotin.

Compliance ready: Formulations available to support REACH and RoHS documentation.

Strong thermal stability: Maintains integrity under elevated processing temperatures.

Smooth processing: Balanced lubricity and dispersion for stable torque, clean die lips, and fewer changeovers.

Reinforced properties: Excellent coupling action that improves weld strength and overall mechanical performance.

Typical Applications

Wires & cables – reliable insulation and long service life.

Window & technical profiles – including foamed profiles with stable color and surface quality.

Pipes & fittings – soil and sewer pipes, foam-core pipes, land drainage, pressure pipes, corrugated pipes, and cable ducting, plus matching fittings.

What You Can Expect in Production

Fast start-ups with stable torque and minimal plate-out.

Consistent whiteness and gloss retention where required.

Good flow and dispersion in both extrusion and calendering.

Support for food-contact or low-odor targets (on request, depending on grade).

Documentation & Support

Compliance statements (e.g., RoHS/REACH) and lab data are available on request. Our technical team can recommend the right Ca-Zn grade and optimize phr & lubrication balance for your line.
