6kg U RESIN ISF136

U RESIN ISF136 is an Integral Skin Polyurethane Foam product with a free rise density of 136 kg/m3. This product contains no CFC’s or HCFC’s and is environmentally friendly foam that has no ozone depleting potential. This system is suitable for mouldings articles where skinned foam is required. This product can be pigmented.

The system can be manually drill mixed (@ a minimum speed of 2000 rpm) but it is preferable to process through a plural component polyurethane dispensing machine.

MIXING PROCEDURES  – To produce a high quality skinned foam, it is essential that the following procedures be carefully followed.

1. The Isocyanate should be accurately weighed into a suitable container. Suitable containers include metal or plastic. Ensure the containers are clean and dry.
2. The Polyol should be mechanically stirred before removing any material. The polyol should be accurately weighed into the same container. The reaction between the two products essentially begins immediately when the two products meet.
3. The product should be mixed with an electric drill to which a paint mixer has been attached. It is essential that the drill is capable of mixing at least at 2000 rpm. A slower speed will produce poor quality foam.
4. The product should be hand mixed for typically 5 seconds. The mixing time will depend on a variety of factors including: Cream time of the material: The product should be mixed and poured into the mould before the cream time has been reached. The temperature of the poly/iso: If ambient and chemical temperatures are too high then the cream time is much faster.

Batch size: Generally a larger batch size will react faster than a smaller batch.
