High efficiency barium-zinc liquid stabilizer

📌 Product Overview

Liquid Barium-Zinc Stabilizer is an environmentally friendly polyvinyl chloride (PVC) processing aid that provides thermal stability through the synergistic action of barium-zinc complexes, replacing traditional lead-based/organotin stabilizers. Its core advantages include:

High stability: inhibits initial PVC coloration, improves long-term thermal and light stability, and reduces process precipitation.

Multifunctionality: both lubrication, good compatibility with PVC, suitable for transparent/colored products.

Key specifications and technical parameters 📏

⚙️Basic Properties:

Appearance: light yellow to light yellow transparent or translucent liquid.

Main components: barium salt of organic acid, zinc salt of organic acid, synergist, solvent/carrier.

Metal ratio: barium (Ba) and zinc (Zn) compounded in a specific optimized ratio

🧪Performance Characteristics:

Thermal stability: Provides excellent long-term dynamic and static thermal stability with good initial color inhibition.

Transparency: Highly transparent products can be produced with good resistance to hydration and whitening.

Compatibility: good compatibility with PVC resin, easy to be dispersed evenly in the system.

Lubricity: both internal lubricant function, help to improve the processing fluidity of PVC melt.

Antiprecipitation: It shows low pressure precipitation and low tendency of spraying frost.

Light stability: good light stability (some specific grades have better performance).

Sulfur staining resistance: Some specific grades have excellent sulfide pollution resistance, which can effectively prevent products from turning black when encountering sulfur.

🏗️Fields of application

Building Waterproofing Materials

PVC Waterproofing Membrane for Roofs/Tunnels (UV-resistant, does not crack at low temperatures of -20°C)

*Note: Must comply with industrial building material heavy metal leaching standards (e.g., GB 18586 barium leaching ≤10mg/m²)

Decorative and advertising materials

Indoor and outdoor advertising display boards (high transparency, haze <5%)

Furniture surface decorative film (cabinet/table top PVC coating, scratch-resistant)

Note: Outdoor use requires the addition of light stabilizers (HALS + UV absorbers)

Industrial consumables

Conveyor belt surface layer (dynamic wear resistance >500,000 cycles, resistant to mineral oil)

Industrial hoses (non-potable water ventilation/water supply hoses, pressure resistance > 0.6 MPa)

Automotive components 🚗

Window seals, door frame gaskets (long-term heat resistance up to 80°C without yellowing)

Semi-rigid ceiling film (no surface migration, gloss > 90 GU)

Note: Must pass VDA 270 odor test (grade ≤3) and ELV directive barium content limit

Surface coating

Plastic floor surface coating (good flowability, Shore A hardness 60–90)

Artificial leather PU surface treatment (improved scratch resistance >1.5 N)

Cable sheathing (non-electronic)

Requirements: Add β-diketone additives (e.g., TTA-25) to enhance thermal stability, operating temperature ≤105°C

Automotive interior trim 🚗

Requirements: Formulate formaldehyde-removing agents (e.g., oxime compounds) to control VOC emissions (aldehyde content <5 μg/m³)
