ZSM Antimony Free Flame Retardant for PVC
I. Product Introduction
The ZSM series is a highly efficient halogen-free composite flame retardant specifically designed for soft materials such as PVC, artificial leather, and synthetic leather. Through specialized blending technology, this product scientifically combines zinc series flame retardant with high-efficiency nitrogen-based flame retardants, achieving a perfect balance between flame retardancy, smoke suppression, and material mechanical properties. It provides an environmentally friendly, safe, and highly effective flame retardant solution.
II. Product Technical Data Sheet

[1] Indicators are laboratory averages and are intended for use as a reference only and are not to be considered as a standard for products.
III. Product Features
1. Highly Synergistic Flame Retardancy
The core zinc series component exhibits exceptional synergistic effects with nitrogen-based flame retardants. Zinc series functions simultaneously in both the gas phase and condensed phase, effectively promoting char layer formation. Nitrogen-based flame retardants generate inert gases when heated, diluting combustible substances and interrupting the chain reaction of combustion. Their combination significantly enhances overall flame retardancy efficiency.
2. Significant Smoke Suppression
Zinc series is a recognized high-efficiency smoke suppressant, substantially reducing dense smoke and toxic gases emitted during combustion of materials like PVC. This is crucial for enhancing product fire safety.
3. Environmentally Friendly
This halogen-free formulation contains no bromine, chlorine, or other halogen elements, complying with stringent environmental regulations (e.g., RoHS, REACH) for green and safe production.
4. Excellent Processability and Compatibility
Featuring uniform particle size distribution, the product exhibits excellent compatibility with PVC matrices. It disperses readily, resists migration, minimally impacts material flow properties, and facilitates production operations.
5. Preserved Material Properties
While providing effective flame retardancy, it maintains the inherent flexibility, tactile feel, and surface gloss of PVC leather, with minimal impact on the material's physical properties.
IV. Application
PVC artificial leather, synthetic leather.
Flame-retardant coatings, adhesives.
Textile coatings.
Other elastomers and plastic products requiring halogen-free flame retardancy.
V. Package Storage & Transportation
1. Packed in a polyethylene lined paper bag, 25kg/bag.
2. Storage in cool dry place.
3. Transported as non-dangerous chemical goods.
4. The minimum shelf life is 24 months from the date of shipment when stored under the above conditions.
