Flame retardant and smoke suppressant
Releases water when heated and reduces smoke, with no halogen.
АТН
Гидроксид алюминия (АТН) Supplier from China
Гидроксид алюминия (АТН) is a halogen-free mineral flame retardant and smoke suppressant for wire and cable compounds, резина, unsaturated polyester (SMC/BMC), artificial stone, epoxy and coatings. SUNCHEM supplies ATH with a batch COA on every shipment; the TDS is sent on request.

Обзор продукта & ключевые преимущества
ATH starts to decompose at about 200 °С, absorbing heat and releasing water vapor that cools the polymer and dilutes the flame; the alumina left behind protects the surface and reduces smoke. Because it is used at high loadings, размер частицы, surface treatment and purity strongly affect processing and mechanical properties.
ATH suits polymers processed below about 200 °С, such as EVA and PE cable compounds, резина, UPR and epoxy. For higher processing temperatures, magnesium hydroxide is used instead.
Filler economics
Used at high loadings as both flame retardant and filler.
Specified on your terms
We quote against your Al₂O₃ content, размер частицы, белизна, oil absorption, влага, soluble Na₂O and surface treatment and send the batch COA for each lot.

Выбор & сравнение
Choosing the right ATH grade
| Ваше требование | Что обычно работает |
|---|---|
| LSZH cable compounds | Fine, surface-treated ATH |
| UPR, artificial stone | Specify whiteness and particle size |
| Processing above about 200 °С | Use magnesium hydroxide instead |
| Replacing an existing supplier | Отправьте текущий TDS или COA; we quote against the parameters you approve |
Упаковка & хранилище
Упаковка
Tell us the bag or drum size and pallet requirements you need; we confirm the packaging with the quotation.
Хранилище
Keep bags closed in a dry store.
От первого электронного письма до одобренной поставки
Name the end use
Name the polymer and the fire rating you must meet — UL 94 class and thickness, LOI or cable standard.
Сравните цифры, которые имеют значение
Particle size (D50), белизна, oil absorption, влага, soluble soda and surface treatment.
Mind the processing temperature
Keep compounding below about 200 °C or ATH starts releasing water.
Trial, then lock the spec
Compound a trial batch, run your fire and mechanical tests, and keep the approved lot COA as the reference.
