在 CAS-AP 标准隔声性能基础上,整体燃烧性能提升至 A2 级,最高使用温度 250℃,满足高安全等级工业场景的隔声与防火双重需求。
Upgraded from CAS-AP with overall fire rating A2 and max service temperature 250℃. Meets dual requirements of sound insulation and fire safety in high-safety industrial applications.
CAS-AP-IIA 在 CAS-AP 多层复合结构(铝镁纤维 + 阻尼隔声层)基础上,采用特殊耐温配方与高安全级材料体系,将整体燃烧性能提升至 A2 级(GB 8624),最高使用温度从 100℃ 提升至 250℃。单层隔声量仍保持 ≥20 dB(A),抗拉强度 ≥1600 kPa,烟气毒性不低于 ZA1 级。
CAS-AP-IIA builds on CAS-AP's multi-layer composite structure (Al-Mg fiber + damping layer) with specialized high-temperature formulation and high-safety material system. Overall fire rating A2 (GB 8624) and max service temperature 250℃ — yet still maintains ≥20 dB(A) STL, ≥1600 kPa tensile strength, and ZA1 smoke toxicity.
适用于人员密集场所、隧道、船舶及高安全等级工业建筑等对防火与隔声均有严格要求的场景。
Ideal for personnel-dense areas, tunnels, marine vessels, and high-safety industrial buildings requiring both fire safety and sound insulation.
单层隔声量 ≥20 dB(A),阻尼层通过粘弹性形变耗散声能,降低声波穿透。
Single-layer STL ≥20 dB(A). Damping layer dissipates acoustic energy as heat, blocking sound penetration.
整体燃烧性能达 A2 级(GB 8624),250℃ 高温环境不自燃、不助燃。
Overall fire rating A2 (GB 8624). Does not ignite or support combustion even at 250℃.
烟气毒性不低于 ZA1 级(GB/T 20285),火灾条件下烟气安全性高,保障人员疏散。
Smoke toxicity not lower than ZA1 (GB/T 20285). High smoke safety during fire for personnel evacuation.
抗拉强度 ≥1600 kPa,多层纤维结构致密坚固,可直接缠绕于管道与异形设备。
Tensile strength ≥1600 kPa. Multi-layer fiber structure suitable for direct wrapping on piping and irregular equipment.
可与 CAS-AX 吸声毡组合使用,先吸声再隔声,提升综合降噪效果
Can be combined with CAS-AX absorbing blanket: first absorption, then insulation for integrated noise reduction
