Frequently Asked Questions

What makes your magnesium hydroxide flame retardants halogen-free?

Our magnesium hydroxide products release water vapor when exposed to high heat, suppressing flames without emitting toxic halogen gases, making them environmentally safe and compliant with RoHS and REACH.

Are your products registered under EU REACH?

Yes, all our products are fully registered under EU REACH regulations, ensuring compliance for use in European markets.

Can you customize particle size or coating?

Absolutely. We offer customization in particle size distribution and surface treatments (e.g., silane, stearic acid) to optimize performance in your specific polymer system.

What certifications do your factories hold?

Our manufacturing facilities are certified under ISO9001 (Quality), ISO14001 (Environmental), and ISO45001 (Occupational Health & Safety). We also have a Dun & Bradstreet code: 554405380.
