Is polyol component B flammable?
Flammability limits: not established. Extinguishing media: Ignition will result in a Class B fire. In case of fire, use Carbo Dioxide (CO2), Dry Chemical, Foam, or Water Spray. Special Fire fighting protective equipment: Use water spray to reduce vapors.

What is contained in section 6 of a SDS?
Section 6: Accidental Release Measures This section provides recommendations on the appropriate response to spills, leaks, or releases, including containment and cleanup practices to prevent or minimize exposure to people, properties, or the environment.
Is polyether polyol toxic?
Hazard statements: Harmful if swallowed. May cause an allergic skin reaction. Causes serious eye irritation. May damage fertility or the unborn child.
What is B side resin?
B-side: The B-side is a polyol resin blend — the principal ingredient being polyol — and smaller amounts of amine and/or metal catalyst, blowing agent, surfactant and flame retardant.
What is polyol resin?
Oligomeric and polymeric polyols are an important group of functional resins which are used in the manufacture of a large number of products. 1. They are typically viscous liquids or waxy solids depending on molecular weight, type of backbone and hydroxyl content.
What is polyether polyol?
Polyether polyols are key components used in the production of polyurethanes. Polyether-based polyurethanes exhibit enhanced hydrolytic stability and excellent resistance to weak acids and bases compared to polyester-based polyurethanes.
Is polyurethane toxic to humans?
What effects does polyurethane have on the health of users? Polyurethane is the result of the chemical reaction between a polyol and a diisocyanate. Once the chemical reaction of its components has taken place, the result is a polyurethane foam that is completely inert and harmless to humans.
What are the types of hardener?
There are many types of hardeners, but the most important ones are classified into aliphatic and aromatic amines, anhydrides, and polyamides. Usually, hardener molecules are much smaller than resin molecules and therefore, have low viscosities.
What is polyol made of?
Polyether polyols are made by the reaction of epoxides with compounds having active hydrogen atom. Polyester polyols are made by the polycondensation reaction of multifunctional carboxylic acids and polyhydroxyl compounds. They can be further categorized according to their end use.
What are the components of MSDS?
If you are using a 9-section MSDS, the types of information may be in a different order and under slightly different headings.
- Product and Company Identification.
- Hazards Identification.
- Composition, Information on Ingredients.
- First Aid Measures.
- Fire Fighting Measures.
- Accidental Release Measures.
- Handling And Storage.
What is a polyol compound?
Medical Definition of polyol : a compound (as sorbitol or pentaerythritol) containing usually several alcoholic hydroxyl groups.
What are the toxins in polyurethane?
Respiratory Issues First, polyurethane is a petrochemical resin that contains known respiratory toxins called isocyanates. When left uncured, polyurethane can cause asthma and other breathing problems.
What is the chemical name of hardener?
A hardener composition for use in producing waste-containing shaped cement articles by mixing broken concrete, cement, waste, and water and shaping the mixture, said hardener composition comprising 4.0 to 13.0 wt. % of sodium carbonate, 5.0 to 10.6 wt. % of potassium carbonate, 5.2 to 11.2 wt.
