Description

DIMONDS^® P1812 is a compounded polyether polyol developed for discontinuous panel use. It is premixed with polyether polyol, silicone surfactant, catalysts and water etc. which has good flow ability and thermal stability.

Typical Properties

Item	Unit	DIMONDS^® P1812	DIMONDS^® ISO1800
Physical state	By visual	Transparent liquid	Brown liquid
Viscosity, 25℃	mpa.s	400-600	150-250
Gravity,20℃	g/ml	1.15±0.05	1.24±0.01

Reaction properties (hand test)

Item	Unit	Specification
Cream time	sec	15-30
Gel time	sec	120-240
Free rise density	kg/m3	26-28

Processing informations

Item	Unit	Specification
Component temperature	℃	22±3
Mold temperature	℃	40±3
Dynamic pressure	kPa	125±10
Demold time	Min	＞30

It is recommended to utilize high pressure foaming machinery. The chemicals should be adjusted to the correct temperature between 20-24℃ to ensure reactivity and viscosity suitable for processing.

The mixing pressure has to be set for both components at 120-130 bar.

The mould temperature recommended is 35-45℃ to guarantee good foam performances.

Foam properties

Item	Unit	Specification	Test standard
Core density	kg/m3	≥35	ASTM D1622-08
Thermal conductivity, 20℃	W/(m.k)	≤0.024	ASTM C518-10
Compressive strength	kPa	≥140	ASTM D1621-10
Closed cell content	%	≥90	ASTM D6226
Water absorb	%	≤3	ASTM C209-12
Thermal stability, -30-80℃	%	≤1.5	ASTM D2126-09

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^® P1812 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 12months for isocyanate.

The optimum storage temperature should be 10-30℃.

Packing

220Kg/drum or 1100Kg/IBC for DIMONDS^® P1812.

250Kg/drum or 1250Kg/IBC for DIMONDS^® ISO1800.
