PF0 Fire-rated PU Foam

Short Description:

Flame retardant single-component polyurethane foam sealant is suitable for sealing and fixing building doors and Windows, heat insulation installation of closed insulation units, sealing, sound insulation, heat insulation, waterproof of pipes, walls, etc., filling of various building structure vacancies and cracks. The occurrence of the fire is to delay the spread of the external fire and the spread of smoke, fight for the rescue time, increase the escape probability of trapped people, and reduce economic losses.

Features

1. Oxygen index ≥26%, foam self-extinguishing from fire;The test meets the flammability B2 class fireproof material standard in JC/T 936-2004 "Single component polyurethane Foam caulk";
2. Pre-foaming glue, after foaming about 20%;
3. The product does not contain freon, no tribenzene, no formaldehyde;
4. The flame retardancy of foam curing process gradually increased, foam curing for about 48 hours, flame retardancy can reach the standard；
5. Foaming ratio: The maximum foaming ratio of the product under appropriate conditions can reach 55 times (calculated with gross weight 900g), and the actual construction has fluctuations due to different conditions.
6. The ambient temperature of the product is +5℃ ~ +35℃ ； Optimum operating temperature:+18℃ ~ +25℃;
7. Curing foam temperature range: -30 ~ +80 ℃ .In a moderate temperature and humidity environment, the foam does not stick to the hand for 10 minutes after spraying, and can be cut for 60 minutes. The product has no harm to human body after curing.
