High Class Fireproof Polyurethane Foam Building Materials System Blend Polyther Polyol for Spray

Product Description

Application
LY-6028 Polyurethane spray foam system (in-situ foam) for the production of rigid foam with closed cells. This system contains flame-retardants and corresponds to building material Class B1 as per DIN 4102, part1. Suitability must be examined by the user prior to the commercial use.

Chemical Characteristics
Polyol Component : Blend of special polyols and other additives.
Blown is provided with CFC free.
Isocyanate Component :  Polymeric diphenylmethane diisocyanate

Supply
The type of supply for the components will be decided after consultation with our Sales Office.

Storage, Preparation
Polyurethane components are moisture sensitive.  Therefore they must be stored at all times in sealed, closed containers.  The A-component (Polyol) must be homogenized by basic stirring before processing.  More detailed information should be obtained from the separate data sheet entitled "Information for in-coming material control, storage, material preparation and waste disposal" and from the component data.

Processing
For processing follow the information provided by our technical adviser.

Possible Hazards
The B-component (Isocyanate) irritates the eyes, respiratory organs and the skin.  Sensitization is possible through inhalation and skin contact.  MDI is harmful by inhalation.  On processing these, take note of the necessary precautionary measures described in the Material Safety Data Sheets (MSDS).  This applies also for the possible dangers in using the A-component (Polyol) as well as any other components.  See also our separate information sheet "Safety and Precautionary Measures for the Processing of Polyurethane Systems."  Use our Training Programme "Safe Handling of Isocyanate."

Waste Disposal
More detailed information is provided in our country-specific pamphlet.

Consumer articles, medical products
There are national and international laws and regulations to consider if it is intended to produce consumer articles (eg. articles that necessitate food or skin contact, toys etc.) or medical objects out of Elastogran's products.  Where these do not exist, the current legal requirements of the European Union for consumer articles as well as medical products should be sufficient.  Consultation with the Elastogran Sales Office and our Ecology and Product Safety Department is strongly recommended.
