Description

DIMONDS^® P1822/PIR is a PIR-rigid foam system for continuous panel with an insulation of thickness of 40-200mm. Suitability must be examined by the user prior to commercial use. We can provide 2 components or 4 components as your requirement.

Typical Properties

Item	Unit	DIMONDS^® P1822/PIR	DIMONDS^® ISO1800
Physical state	By visual	Transparent liquid	Brown liquid
Viscosity, 25℃	mpa.s	300-500	150-250
Gravity,20℃	g/ml	1.20±0.05	1.24±0.01
Package	Kg/drum	220	250

Reaction properties (hand test)

Item	Unit	Specification
Cream time	sec	10-20
Gel time	sec	35-65
Free rise density	kg/m3	30-36

Processing temperature

Component temperature	℃	25±3
Temperature of facing layers	℃	40±3
Temperature of double belt laminator	℃	55±5
Dynamic pressure	kPa	130±10

It is recommended to utilize high pressure foaming machinery. The chemicals should be adjusted to the correct temperature between 22-27℃ to ensure reactivity and viscosity suitable for processing.

The mixing pressure has to be set for both components at 120-140 bar.

Foam properties

Item	Unit	Specification	Test standard
Core density	kg/m3	≥37	ASTM D1622-08
Thermal conductivity, 20℃	W/(m.k)	≤0.021	ASTM C518-10
Compressive strength	kPa	≥140	ASTM D1621-10
Thermal stability, -30-80℃	%	≤1.5	ASTM D2126-09
Flammability		B2	DIN 4102

The above testing data have been generated in lab or field conditions which are typical for this application. They are believed to be correct but data variations due to varying processing or ambient conditions can not be excluded. The customer remains responsible for making his own interpretation of data and suitability of the chemicals to his particular operation.

Handling and Storage

DIMONDS^® P1822/PIR should be protected from moisture by keeping containers sealed when not in use. Drums have to be stored indoors to protect the material from water ingress, frost and direct heat from the sun. Under temperature conditions and in properly sealed containers, the storage life of the polyol is 6 months and 12 months for Isocyanate.

The optimum storage temperature should be 10-30℃.The optimum storage temperature should be 10-30℃.
