2、cation This method is used to determine the foam formation of polyols and isocyanates into polyurethane foam parts in a complete form. The polyol is tested with isocyanate and the isocyanate with the polyol compound. Apparatus Required Standard Foam Form Fitted with lock and key and conditioned with

3、 the following form and dimension (see Figure 1). Laboratory Stirrer With a mixing rotor of approximately 90 mm diameter. Speed of rotation: approximately 1380/minute. Temperature Controlled Water Bath Capable of maintaining 23 C +/- 1 C to condition the components. Analytical Balance Ventilated Fum

Condition and coat the foam mold to specification requirements with the released agent used in production. 2. Pour the component

6、s A + B at a temperature of 23 C +/- 1 C into a plastic pail of known weight. (Weight according to specification requirements.) 3. Immediately after adding component B, stir the mixture for the specified time and fill the open, heated foam mold with the mixture. Note: Weight and mix the components u

Test the indentation hardness after 1 h conditioning at 23 C +/- 2 C and 50 % +/- 5 % relative humidity (test method a

9、ccording to ISO 2439, Method A; test area according to Figure 1). 7. The indentation hardness must be in line with the specification requirements. Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities.
