Polyurethane foaming agent:
Where can I sell polyurethane foaming agents for spot supply? Polyurethane foaming agent manufacturers produce polyurethane foaming agents? Where is the production of polyurethane foaming agents?
One component polyurethane foam sealant, commonly known as foaming agent, foam adhesive, PU sealant, PU FOAM is the cross combination of aerosol technology and polyurethane foam technology. It is a special polyurethane product that packs components such as polyurethane prepolymers, foaming agents, catalysts, etc. into a pressure resistant aerosol tank. When the material is ejected from the aerosol tank, the foamed polyurethane material will rapidly expand and solidify with air or the moisture in the contacted matrix to form foam. Widely applicable. With the advantages of pre foaming, high expansion, small shrinkage, etc., and good strength of foam, high adhesive force, the cured foam has a variety of effects such as caulking, bonding, sealing, heat insulation, sound absorption, etc. It is an environmentally friendly and energy-saving building material that is easy to use. It can be used for sealing and plugging, filling and caulking, fixed bonding, heat insulation and sound insulation, especially for sealing, plugging and waterproofing between plastic steel or aluminum alloy doors and windows and walls.
Performance description:
The general surface drying time is about 10 minutes (at room temperature of 20 ℃), and the full drying time varies with the ambient temperature and humidity. Generally, the full drying time is about 4-6 hours in summer, and around zero ℃ in winter, it takes 24 hours or more to fully dry. Under normal use conditions (and when there is a coating on its surface), its service life is estimated to be no less than ten years, and the cured foam body maintains good elasticity and cohesion within the temperature range of -10 ℃~80 ℃. The cured foam has the functions of caulking, bonding, sealing, etc. In addition, flame retardant polyurethane foaming agents can achieve B and C level flame retardancy.
Packaging: 200 kg/barrel
