Selected by core performance classification
Standard universal foam
Performance characteristics: density 25-30kg/m³, expansion rate 300%-400%, after curing, it has the ability to seal, sound insulation, and heat preservation, and the temperature resistance range is -20°C~80°C
Applicable scenarios: filling gaps between door and window frames and walls, sealing gaps in indoor ceilings, and simple pipe wrapping
Selection suggestions: Give priority to entry-level products from well-known brands, pay attention to environmental protection certifications (such as ten-ring certification), suitable for general decoration needs with limited budgets
Representative products: Sudiao SF-100, Henkel Black & Decker universal foam
Fire retardant and flame retardant foam
Performance characteristics: UL94V-0 or GB8624 B1 level fire certification, smoke density ≤50, can form a carbonized layer to prevent the spread of fire when encountering fire, and some products have waterproof functions
Applicable scenarios: fire partition sealing, cable hole sealing, gap filling in high-temperature areas such as kitchens/boiler rooms, and fire protection projects in public buildings
Selection suggestions: Be sure to confirm the fire level certificate of the product, give priority to products with low smoke density and fire resistance limit ≥ 2 hours, and provide fire test reports for large projects
Performance characteristics: compressive strength ≥ 0.3MPa, density 45-50kg/m³, with a certain structural support capacity after curing, and the bonding strength can reach more than 80kPa
Applicable scenarios: installation of lightweight partition wall panels, structural fixation of door and window frames, filling of elevator shafts, filling gaps in equipment foundations
Selection suggestion: Choose products that meet the GB/T20219-2015 standard, pay attention to the compressive strength and bonding strength parameters, and reserve sufficient curing time (more than 72 hours) during construction.
Performance characteristics: temperature resistance range -40°C~100°C, can still cure normally in low temperature environment, foam elasticity is good, and will not be brittle and cracked due to sudden temperature drop
Applicable scenarios: outdoor construction in winter in the north, sealing of cold storage buildings, insulation of cold chain transportation equipment, and anti-freezing of pipelines in alpine areas
Selection suggestions: Choose products with silicone oil ingredients to improve low-temperature fluidity and frost resistance, and the construction temperature is recommended not lower than -10°C
Precise selection according to application scenarios
Home renovation scene
Door and window installation: Prefer standard universal or structural heavy-duty foam to take into account the sealing effect and installation firmness
Kitchen and bathroom decoration: Choose waterproof and mildew-proof foam, which has the functions of anti-moisture and inhibiting mold growth
Sound insulation transformation: choose foam with high closed-cell rate (close-pore rate≥90%), thermal conductivity ≤0.03W/(m·K)
Local repair: Choose foam with a small pipe diameter (300ml) to facilitate the construction of small gaps and avoid waste
Commercial engineering scenarios
Exterior wall insulation: Choose high-density (≥35kg/m³) foam with good wind pressure resistance and weather resistance
Fire protection engineering: Fire retardant and flame retardant foam must be used, and it is required
