POLYSYSTEM 450

Recommendations for processing:

The key conditions for the qualitative filling of a form with polyurethane foam are: compliance with the accuracy of dosing and temperature conditions of the PU-system components' processing regime; sufficient mass of the poured PU-system portion; required temperature of the form (mold).
POLYSYSTEM 450 PU-system is processed by filling open or closed metal molds of various sizes and configurations by means of high- or low-pressure machines, or manually. Before the actual filling, the molds are cleaned and lubricated with anti-adhesive lubricant (based on waxes, oils, silicones, etc.), which ensures easy and quick removal of finished products. Optimal temperature of the mold working surface is (25 - 35) °C.
Before processing, the components are thermostated up to (20 ± 2) °C.
The product curing time is 10 - 20 minutes (depending on its size and configuration). Once the curing time is over, the product is removed from the mold and kept for 24 hours in a room with a temperature not lower than 18 °C - to ensure the final curing of polyurethane foam.
Technical documentation for the equipment and the process of obtaining finished products are the guidelines for the PU-system processing.
