Flame retardant and smoke suppressant
Releases water when heated and reduces smoke, with no halogen.
水酸化アルミニウム (ATH) is a halogen-free mineral flame retardant and smoke suppressant for wire and cable compounds, ゴム, unsaturated polyester (SMC/BMC), artificial stone, epoxy and coatings. SUNCHEM supplies ATH with a batch COA on every shipment; TDS はリクエストに応じて送信されます.
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, 粒子サイズ, surface treatment and purity strongly affect processing and mechanical properties.
ATH suits polymers processed below about 200 ℃, such as EVA and PE cable compounds, ゴム, UPR and epoxy. For higher processing temperatures, magnesium hydroxide is used instead.
Releases water when heated and reduces smoke, with no halogen.
Used at high loadings as both flame retardant and filler.
We quote against your Al₂O₃ content, 粒子サイズ, 白さ, oil absorption, 水分, soluble Na₂O and surface treatment and send the batch COA for each lot.
