QH-6206 Pipeline Insulation

QH-6206 High-Flame-Retardant Pipeline Insulation Rigid Foam Polyether (Suitable for High-Demand Pipelines)

1. Description

This product is a high-end rigid foam polyether polyol for pipeline insulation, made from sorbitol and amines as initiators , added with special flame-retardant additives, adhesion promoters and anti-aging agents. It is a light yellow viscous liquid, with excellent flame retardancy (GB 8624-2012 Class B1), high closed-cell rate (≥90%), strong bonding force with various pipeline substrates (steel pipes, stainless steel pipes, aluminum pipes), and good water resistance, corrosion resistance and aging resistance. Its high functionality ensures excellent dimensional stability of the foamed insulation layer, which is suitable for pipeline insulation with high fire protection, high durability and long service life requirements, such as high-rise buildings, chemical industry and key projects.

3. Application

Core application scenarios:

• High-Rise Building Pipelines: Thermal insulation of heating, air conditioning and fire-fighting pipelines in high-rise residential buildings and office buildings, which can delay fire spread and meet strict fire protection requirements of high-rise buildings.
• Chemical Industry Pipelines: Insulation of chemical fluid transportation pipelines, dangerous goods transportation pipelines and reaction equipment pipelines in chemical plants, with flame retardancy, corrosion resistance and good insulation performance, adapting to harsh working environments.
• Key Projects: Pipeline insulation for airports, hospitals, schools and stadiums, with high strength, good durability and long service life, meeting the high standards of key projects.
• Extended Applications: Insulation of high-end industrial pipelines, such as petroleum transportation pipelines, natural gas pipelines, improving the safety and stability of pipeline operation.
• Construction Instructions: Mix with special flame-retardant isocyanate at 1:1 (25℃), suitable for factory prefabrication and on-site high-pressure spraying. Production temperature: 15~35℃, humidity <70%; strictly control the mixing ratio and foaming time to ensure uniform foam and seamless fit with the pipeline. Comply with GB 50264-2013 and GB 8624-2012; set up a special no-fire area on the construction site and strengthen fire prevention measures.

4. Storage

• Storage Environment: Special cool and dry warehouse (5-30℃), away from fire, heat sources and direct sunlight, equipped with complete fire-fighting and explosion-proof facilities, and isolated from flammable and explosive materials.
• Packaging: 200L corrosion-resistant sealed drums, marked with "Flame-Retardant", "Pipeline Insulation Special" warnings and product information, and attached with safety data sheet (SDS).
• Shelf Life: 6 months; after expiration, it is necessary to re-test flame retardancy, hydroxyl value, bonding strength and closed-cell rate, and it can be used only after passing the test.
• Transportation: Use dangerous goods qualified vehicles, avoid high temperature and sun exposure, do not mix with flammables, oxidants and acids, and comply with national transportation regulations; take shockproof and anti-leakage measures.
• Others: Operators must wear protective equipment (gloves, goggles, masks); if it splashes into eyes, rinse with plenty of water for more than 15 minutes and seek medical advice in time; waste materials and packaging drums must be disposed of in accordance with environmental protection regulations and fire safety requirements.
