POLYSYSTEM 450 two-component PU-system is designed for the manufacture of thermal insulation "shells" and other molded products by the mold-filling method.



POLYSYSTEM 450 two-component PU-system is designed for the manufacture of thermal insulation "shells" and other molded products by the mold-filling method. The system does not contain ozone-depleting freons; foaming agent - CO2 (water).

Polyurethane foam obtained from the components of POLYSYSTEM 450 PU-system is characterized by excellent curing properties and uniform structure, as well as by top durability and thermal insulation properties.
System description:

POLYSYSTEM 450 Component A is a mixture of simple polyethers, foaming agents and functional additives.

Component B is polymeric diphenylmethanediisocyanate of low viscosity (PMDI/PIC: WannatePM-200, Desmodur44V20L, LupranateM20 S, VoranateM229, VoratecSD100 and their counterparts produced by other manufacturers).

Typical indicators:

* after the component homogenization.

Foaming parameters (mass ratio of Components A : B = 100 : 150)
Foaming conditions: stirring with a mixer for 15 s at a rotation speed of 3000 min-1. Components' temperature during foaming: (20 - 22) °C. Foaming characteristics may vary depending on the foaming conditions.

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.
