Key Benefits
Robust heat stability for steady extrusion and smooth torque
High initial whiteness; good weatherability; anti-sulfidation
Clean melting & welding → stronger joints, improved pressure rating
Good dispersion & flow → fewer die deposits, lower wear on barrel/screw
RoHS-compliant formulation; proven in production; helps reduce overall processing cost
Typical Applications
PVC pressure/non-pressure pipes (cold/hot water, drainage, conduit)
PVC fittings and extruded profiles used in piping systems
Recommended Use
Start from your current stabilizer phr and finalize on line. Balance internal/external lubricants to maintain a flat torque curve, clean die lips, and high whiteness. For colored pipe, validate pigment compatibility and impact modifiers.
Compliance & Documents
Meets EU RoHS screening limits. Test reports & compliance statements available on request.
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.
