How is foam rubber processed?

Polyurethane foam is now widely used in the construction industry, especially in some home decoration and building materials. Polyurethane foam has always been a good material. Many consumers don’t quite understandpolyurethane hair What is foam made of? . This timeWeigu editor font> will simply tell you what styrofoam is . Polyurethane foam What material is it made of?

Polymethyl polyphenyl isocyanate (MDI) black material is the main raw material of polyurethane foam caulking agent. Polyurethane foam 中黑What is the ratio of material to white material,In fact, it means how much black material is put in. Polyurethane foam The content of metered-dose inhalers directly determines and represents the current market Polyurethane foam ‘s quality. There are many manufacturers of black materials, and of course the quality and price are also different. The quality of black materials is mainly determined by the iron ion content in the black materials.

How to judge whether products with the same price have more or less black material content? This is very simple,Generally speaking, The black material has multiple strengths and hardnesswill be relatively better.

Combined white material

It is mainly composed of chlorinated paraffin, polyether polyol, foam stabilizer and catalyst.

The flame retardant type is mainly composed of flame retardant, polyether polyol, foam stabilizer and catalyst.

Dimethylether

The market is divided into two types, one is refined ether and the other is crude ether.

Spiritual ether has a very small smell, usually the content is above 999.5%, and basically does not contain water.

crude ether has a strong smell and the content is only 99%. The water content will cause The shelf life will be shortened and manifested as stickiness and crystallization.

Probutane

Probutane can also be divided into good and bad. First of all, propylene butane is more expensive than dimethyl ether. Dimethyl ether contains more glue and is cheaper, but it is dilute. Propylene butane participates in the reaction. Usually the longer the butane propane is released, the longer the rice will grow. Many small factories will release dimethyl ether vigorously in summer.

The choice of polyurethane foam is really important to family life. With more and more usage, the overall benefits are getting better and better, and it is used by many Consumers like it. However, consumers are now paying more and more attention to product quality, which requires us to understand the basic materials of polyurethane foam. When you choose, you will understand it better and feel more at ease. Reasonable selection and use of polyurethane foam is very effective for quality control of building doors and windows.
