The difference between foam glue and sealant

Foam glue and sealant are materials commonly used in the construction industry. The of the product is quite different, such as different main ingredients, different places of use, etc. wait. In order to understand the difference between the two in detail, authorDetailed introductionFoam glue and sealantdifference.

1. Styrofoam

Full namePolyurethaneFoam caulk , also known as foaming agent andPU caulking agent.

PolyurethaneFoam glue is a special polyurethane product that fills polyurethane prepolymer, foaming agent, catalyst and other components into a pressure-resistant aerosol can . When the material is sprayed from the aerosol can, the foamy polyurethane material will rapidly expand and solidify with air or moisture in the matrix in contact to form foam.

Curedstyrofoam foamWith caulking, bonding, sealing, heat insulation,segmentsound and other effects, is an environmentally friendly, energy-saving, easy-to-use building material font>, Widely used for caulking, sealing and fixed bonding between doors, windows and walls,Especially suitable for sealing, plugging and preventing leaks between plastic steel or aluminum alloy doors, windows and walls.

The application scope of styrofoam includesthe production of models and sand tables font>, Exhibition board repair;When renovating speech rooms, broadcasting studios, etc. Filling the gaps, can play the role of sound insulation and silencing;Flower arrangement, gardening and landscaping, light and beautiful; Cavities, gaps, wall tiles, floor tiles, floor repair; water pipes, sewers and other loopholes Repair and plug leaksetc.

2. Sealant

Sealant means that it deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesionSealing material. It is used to fill the gap in the configuration to achieve a sealing effectAdhesive.has anti-leakage, waterproof, anti-vibration and Sound insulation, heat insulation and other functions.

Usually made of asphalt and natural resin Or dry or non-drying viscous materials such as synthetic resin, natural rubber or synthetic rubber as the base material ,with talcum powder, clay, Inert fillers such as carbon black, titanium dioxide and asbestos, It is made by adding plasticizers, solvents, curing agents, accelerators, etc. It can be divided into three categories: elastic sealant, liquid sealing gasket and sealing putty. It is widely used in the sealing of construction, transportation, electronic instruments and parts.

Construction sealants are used to seal various joints or holes in buildings to prevent gases, liquids, and solids from penetrating, and to prevent structural materials from being damaged when the structure is displaced, thereby achieving thermal insulation, sound insulation, waterproofing, and waterproofing. Dust, gas, fire, corrosion, shock absorption and prevent the accumulation of foreign matter in the joints.

Building sealants can be classified according to their composition. Currently, there are many types of polysulfide rubber, chloroprene rubber, acrylic, polyurethane, butyl rubber, silicone rubber, rubber-plastic composite, thermoplastic elastomer, etc.;It can also be divided into hot coating type, cold coating type, curing reaction type and solvent volatile type according to the construction form; It can also be divided into doors and windows, caulking, waterproof and shock-proof, prefabricated walls, etc. according to their uses.

The above is an introduction to the differences between foam glue and sealant. If you want to know more information about construction adhesives, you can pay attention to Shanghai Weigu.
