MSDS is not a general technical specification and needs to be made according to the information of the product, so to provide MSDS, you need to provide complete ingredient information, percentage, etc.

Do you have the ingredients for styrofoam? Maybe I can help you.

Give me your email address, I have an English copy here I don't know if it's useful for you.

We can compile MSDS for each product for you

It is best to use styrofoam sparingly, because there is a chemical in it that is slowly released, which will cause enrichment in the human body, and the higher the concentration of accumulation, the greater the degree of harm. Therefore, the general plastic products should be used as little as possible, especially in the practical aspect, it is released slowly, but the enrichment in the human body will be presented when it reaches a certain level, which will cause cell carcinogenesis and lesions.

Most of the styrofoam components used now are polyurethane (the main component of paint), pay attention to ventilation and ventilation when using, it is recommended to buy products produced by regular manufacturers, and open windows for ventilation after decoration.
Polyurethane styrofoam is an environmentally friendly product and a new type of building material recommended by the state.
There will be a certain smell when blowing styrofoam, and the size of the smell depends on the product of the manufacturer you choose, which can also reflect the quality of the product on the one hand. The cured styrofoam can come into contact with food.
However, since styrofoam is still a chemical, everyone should pay more attention when using it.
Introduction] Styrofoam is a kind of glue with foaming properties and adhesive characteristics, which is mainly used for filling, sealing and bonding at the edge joints of building doors and windows, expansion joints and holes of components. It is a polyurethane elastomeric sealing foam that relies on moisture curing. Styrofoam is composed of polyurethane prepolymer, foaming agent, catalyst, crosslinker, etc. filled into a high-pressure resistant iron can, and filled with propane and other gases.
It is divided into two types: gun type and tube type, the gun type is required to use a special polyurethane foam gun, and the tube type is equipped with a disposable hose.
Principle] Styrofoam, as the name suggests, is a kind of glue with foaming properties and adhesive characteristics, which is mainly used for filling, sealing and bonding at the side joints of building doors and windows, expansion joints and holes of components. It is a polyurethane elastomeric sealing foam that relies on moisture curing. Styrofoam is composed of polyurethane prepolymer, foaming agent, catalyst, crosslinker, etc. filled into a high-pressure resistant iron can, and filled with propane and other gases.

Are sponge foaming agents toxic? What are the advantages of sponge foaming agents.
-
The product is non-toxic after curing. Full curing usually takes about 24 hours.
-
Hello, I have seen your question and am sorting out the answer, please wait a while
-
AC foaming agent is widely used in the processing of polyvinyl chloride, polyethylene, polystyrene, ethylene-vinyl acetate copolymer, ABS resin and various rubber, etc., it has a large foaming capacity, short decomposition time, non-combustible, non-toxic, odorless, non-polluting, no discoloration, fine particles, easy to decompose and can be used under atmospheric pressure, pressure can be used in the special ridge point, the most widely used at home and abroad.
Haha, it's a pity I'm not the first mate, but it looks like a dangerous product.
-
The scientific name of AC blowing agent is azodicarboxamide, which can be found in the list of dangerous goods.

Hello, it is a dangerous good.
Styrofoam is a mixed solvent, which belongs to three types of dangerous goods, and should be ventilated and fireproof when used.
One. Polyurethane blowing agents are the product of the cross-combination of aerosol technology and polyurethane foam technology. The two types of the split type and the gun type appear in the sponge state.
Styrofoam is used as a foaming agent for the production of bridge silver microcellular foam, which can generally be divided into two categories: physical type and chemical type, which is divided according to whether the generation of gas is a physical process (i.e., volatilization or sublimation) or a chemical process (i.e., the destruction of chemical structure or other chemical reactions). Ermin laughing feast. Performance Description:
Generally, the surface drying time is about 10 minutes (under the environment of room temperature 20 years), and the total drying time varies with the ambient temperature and humidity, under normal circumstances, the total drying time is about 4-6 hours in summer, and it takes 24 hours or more to dry around zero degrees in winter. Under normal conditions of use (and with a covering layer on its surface), it is estimated that its service life is not less than ten years, and the cured foam retains good elasticity and adhesion in the temperature range of -10 to 80. The cured foam has no functions such as caulking, bonding, and sealing.
In addition, the flame retardant polyurethane blowing agent can achieve B and C flame retardant.

Generally, styrofoam is non-toxic and odorless after drying. In the case of low-quality styrofoam, the toxicity disappearance time needs to be determined according to the toxicity of the production material.
Precautions for storage:
The normal use temperature of the styrofoam tank is +5 +40, and the optimal use temperature is +18 +25.
Precautions for use:
a. Styrofoam is a moisture-curing foam, which should be sprayed on a moist surface when used, the greater the humidity, the faster the curing. The cured foam will turn yellow when exposed to ultraviolet light, so it is recommended to coat the cured foam surface with other materials.
b. When replacing the tank, shake the new tank well, remove the empty tank, and quickly replace the new tank to prevent the gun connection from curing.
c. The flow control valve and trigger of the spray gun can control the size of the foam flow. When the injection stops, the flow valve is closed in a clockwise direction.
Safety Precautions:
The uncured foam is sticky to ** and clothes, do not touch ** and clothing styrofoam cans have a pressure of 5-6kg cm2 (25) in the can, the temperature should not exceed 50 during storage and transportation, avoid direct sunlight, it is strictly forbidden for children to touch, empty cans after use, especially the styrofoam cans that are partially used and have not been used up should not be thrown away, and it is forbidden to burn or puncture empty cans. Keep away from open flames and do not come into contact with flammable and explosive materials. If the foam comes into contact with the eyes, it should be rinsed with water in time before going to the hospital for medical treatment; If it comes into contact with **, rinse with water and soap.

The State implements a safety production licensing system for mining enterprises, construction enterprises, and enterprises producing hazardous chemicals, fireworks, and civil blasting equipment (hereinafter collectively referred to as enterprises).
Enterprises that have not obtained a safety production license shall not engage in production activities.
Polyurethane is a hazardous chemical, and its related processing and production enterprises need to apply for a safety production license.

Not yet. However, there is an industry standard, JC936-2004
Increase air humidityWhen using styrofoam, it is necessary to keep the humidity between 30% and 80%. The most suitable humidity is 45%-55%, which can better exert the performance of styrofoam. In winter, the air is very dry, so a small amount of water vapor can be sprayed before construction to increase the humidity of the air. >>>More

802-40, generally in the form of rubber**, slightly higher. There are two versions of the rubber set: Japanese sponge and German sponge, of which the Japanese sponge version has slightly stronger fast attack performance and faster speed; The German sponge version of the ball is deeper, has more power, and is easier to exert the power of a small arc ball.
Of course, home decoration is inseparable from ceramic tiles, so tile adhesive is indispensable. It's just that tile adhesive can't be used indiscriminately, are you doing the right way to use the following? 1. Apply the glue to the working surface with a toothed scraper to make it evenly distributed and form a toothed shape. >>>More
