Styrofoam price, is styrofoam toxic, styrofoam production formula

With the progress and development of society, people are more interested in The requirements for healthy living are also getting higher and higher. Foam glue is a kind of glue with foaming and bonding properties. It is mainly used for side seams of building doors and windows, component expansion joints and holes. Filling, sealing and bonding are very commonly used decoration materials in modern home decoration.

1. How much does styrofoam cost?

The price of styrofoam is generally between It ranges from a few yuan a piece to more than thirty yuan a piece. If it is for personal home use, for example, if you only need to buy one to fill mouse holes, air conditioning holes, etc., you can buy it on e-commerce platforms such as Taobao, JD.com, and Alibaba. Basically 500ml is enough, the price is generally between 15 yuan and 30 yuan, the higher the product performance , the price is also higher. If it is wholesale, or used in large quantities in engineering projects, and you go directly to the manufacturer to buy in large quantities, the price generally ranges from a few yuan a piece to more than 20 yuan a piece. Some high-end projects, projects with brands specified by Party A, have very high quality requirements for the foam used. The price of such products is basically around 20, and the market calls such products A1 quality. Some low-end small projects, or the home improvement market, use products with slightly poor performance, and the price is about 11 yuan to 16 yuan. Such products are generally called A2 and A3 in the market. There is also a category of circulating goods, whose quality is lower than A3. This kind of product has poor performance and low price, below 10 yuan. The author does not recommend that everyone use this kind of product because the quality is not guaranteed.

2. Is styrofoam toxic?

Most of the styrofoam components used today are polyurethane (the main component of paint). Pay attention to ventilation when using it. Breathable, it is recommended to buy products produced by regular manufacturers, such as Shanghai Weigu, After the decoration is completed, open more windows for ventilation. Polyurethane foam is an environmentally friendly product and a new building material recommended by the country. When playing with foam, there willhave There is a certain smell. The size of the smell depends on the product of the manufacturer you choose. On the one hand, it is also It can reflect the quality of the product. The cured foam glue can come into contact with food. But because styrofoam is still a chemical, when using it, everyone Be more careful.

3. Foam rubber production formula

The core of foam rubber production is the production technology formula, that is, the foam rubber production process and foam rubber formula.

The foaming rubber formula contains two liquids and two gases, and the core foaming rubber formula is two kinds of liquids, one is called black material and the other is called white material. The black material is unified , extracted from petroleum, the price also rises and falls with the price of petroleum, and the core of the foam rubber formula is still the white material formula, because the cost control of a bottle of foam rubber finished product comes from the foam rubber white material formula.

Foam rubber black material is a It contains a mixture of a certain amount of isocyanate with higher functionality and diphenylmethane diisocyanate (MDI). The functionality is about 2.6 to 2.7. It is a dark brown liquid at room temperature with a viscosity of Larger than polyurethane white material (combined polyether).

The name of the foaming rubber white material is combined polyether (polyol), which is mixed with polyols, flame retardants, catalysts, foaming agents and other auxiliaries. The color is lighter, light yellow or light brown, and changes with the temperature of the four seasons. , environmental changes, you can purchase the raw materials and prepare it yourself, so that the formula can be adjusted at any time, which is conducive to stable production.
