What is your minimum order quantity (MOQ)?
Our standard MOQ is 1000 kg per product. For samples and trial orders, smaller quantities are accepted.
Will SF-400 affect the physical properties of the polymer?
No. As an eco-friendly silicone-based synergist, SF-400 enhances flame retardancy without compromising the polymer’s physical properties.
Do your flame retardants replace antimony trioxide (ATO)?
Yes. Our SF-400 product is a 100% substitute for ATO, with better smoke suppression and cost efficiency.
What is the recommended dosage of SF-400 when replacing antimony trioxide?
SF-400 can serve as a 100% replacement for antimony trioxide and is generally added at the same ratio in resins such as PP, PE, PVC, and ABS. However, the optimal dosage may vary slightly depending on the polymer type. Please let us know your specific material, and we’ll provide tailored recommendations.
Are test samples available upon request?
Yes, we provide 1kg trial samples for material validation, with freight collected or using your express account.
What payment terms do you accept?
We accept T/T (30% in advance, 70% before shipment). L/C is negotiable for bulk orders.
How long is the lead time for production and delivery?
For regular products, 7–15 working days after order confirmation. For customized formulas, 15–20 days depending on complexity.
Do you offer bulk discounts?
Yes. Volume-based discounts are available. Please contact our sales team for tiered pricing.
What certifications do your flame retardants comply with?
Our products comply with RoHS, REACH, California Proposition 65, CHCC, and are compatible with UL94 V-0 standards. Relevant certification documents are available upon request.
