PU foam for domestic produce a misconception that must produce a lot of toxic gases after combustion of PU foam , which can not be made of such material as the inner and outer insulation building insulation materials, this view with a certain one-sided nature . In fact, the polyurethane itself is non-toxic , fridge freezer insulation materials in contact with food are polyurethane foam , polyurethane elastomer can make artificial blood vessels and heart valves , everyone wore clothes with spandex , which is also the polyurethane spandex their school called polyurethane elastic fiber .Washi tape
The main component is a polyurethane foam containing carbon, hydrogen , oxygen, nitrogen , and less than 10% . Therefore, the combustion gases are usually able to find the main component is carbon dioxide , carbon monoxide and water, and other oxidation products , Masking tape
and a low concentration of hydrogen cyanide . Experiments show that : Polyurethane combustion process does not produce toxic gases than our common substance containing more than N elements , such as wool , acrylic , synthetic timber. Where this is the most common laboratory test German standard DIN 53436. The standard can be used to compare product features under fire conditions corresponding to various different temperatures and air flow . Wholesale masking

Hazardous substances generated during combustion intensity foam and soft polyurethane foam material of the same volume of the sample under conditions of decomposition products generated in the timber equivalent to the predetermined combustion ratio condition hazards arising blankets and leather concentration low . In addition, the composition of the products of combustion PU foam is not toxic gases can not be changed, but not necessarily , depending on the structure of PU foam and flame retardant and smoke suppressant taken through scientific research methods , can developed into products of combustion smoke density , low toxicity of PU foam products.Sellotape
