Flame retardant and smoke suppressant
Releases water when heated and reduces smoke, with no halogen.
ATH
수산화알루미늄 (ATH) Supplier from China
수산화알루미늄 (ATH) is a halogen-free mineral flame retardant and smoke suppressant for wire and cable compounds, 고무, 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.

제품개요 & 주요 이점
ATH starts to decompose at about 200 ℃, 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, 입자 크기, surface treatment and purity strongly affect processing and mechanical properties.
ATH suits polymers processed below about 200 ℃, such as EVA and PE cable compounds, 고무, 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, 입자 크기, 흼, oil absorption, 수분, soluble Na₂O and surface treatment and send the batch COA for each lot.

첫 번째 이메일부터 승인된 공급까지
Name the end use
Name the polymer and the fire rating you must meet — UL 94 class and thickness, LOI or cable standard.
Compare the numbers that matter
Particle size (D50), 흼, oil absorption, 수분, 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.
