Polyurethane foamIt is a low-density foam-like material. After curing, it has the properties of waterproofing, insulation, moisture-proof, leak-proofing,sealing,Light weightetcFeatures. This material has been widely developed and used. It can be classified according to the raw materials of the ingredients. Common polyurethane foam glue is divided into two types: single-component and two-component.
One-component foam rubber and two-component foam rubberWhat’s the difference?
Single componentAdvantages of styrofoam: single set The foam glue is easy to operate and divided into gun type and tube type. The tube type is more suitable for home use. Gunstyle foams evenly,High foaming density , can be used in industrial manufacturing industries with higher foaming requirements. At the same time, one-component foam glue is easy to operate and has a simple process.
Two-componentFoam glueAdvantages: Two-component foam glue can be divided into hard foam glue and soft foam glue, and can also be divided according to the foaming speed. Two-component foaming glue has no effect if one component is used alone. The two components need to be mixed in a certain proportion to achieve the foaming effect.
Two-component polyurethane foam can be prepared in large quantities at one time, and the construction speed is faster using machines. Compared with single-component polyurethane foam, the construction speed is effectively improved. The product can be effectiveUsed in new energy, military, medical, aviation, ships, Electronics, automobiles, instruments, power, high-speed rail and other industries.
Single-component foam glue will undergo a curing reaction as long as it comes into contact with air. Whether it is single-component foam or two-component foam, the volume will expand many times after curing, so you need to be familiar with construction techniques during construction, which can save glue and reduce costs.
Due to single componentFoam glueand two-componentFoam glueThe raw materials are different,There are also some differences in how to use it,Each has its own characteristics,cannot Compare which one is better. When purchasing, just buy the right product and use the correct construction technology to achieve the expected use effect.
