REACTIVITY PROCEDURE
PRODUCTION AND QUALITY CONTROL
25
REACTION PROFILE: The sequential stages, that is, the String-Gel and Tack-Free times, from the time
the ISO (A) and POLYOL (B) are mixed/dispensed until the urethane reaction is complete.
REACTION PROFILE Q.C. – Measuring, recording and comparing the stages and comparing to the
specific system Technical Data Sheet. For daily production purposes, String-Gel measurement is the
focus and suggested minimum Q.C. check.
STRING-GEL – The duration of time from the moment when the chemical is mixed/dispensed until the
foam adheres to a thin wire (approximately 1/16" in diameter, similar diameter to a wire coat hanger) and
becomes “stringy” like bubble gum.
Necessary Items:
• 30 gallon or larger plastic bag
• Large box, receptacle or trash can
• Stop watch or other timing device
• 1/6" diameter wire (similar diameter to a wire coat hanger)
STRING-GEL MEASUREMENT PROCEDURE: (6-PPM, 15-PPM, OR 30-PPM SLUG PRO)
1. Dispense a 10 second shot into a plastic bag and simultaneously start stop watch.
2. 10 seconds prior to the specific system STRING-GEL, provided on the Technical Data Sheet, begin
poking 4"–12" deep into the rising foam with wire. Repeat at 5 second intervals into a fresh foam
surface until the foam sticks to the wire and reaches a “stringy” bubble-gum like consistency.
3. Record time when foam reaches “stringy” consistency.
STRING-GEL MEASUREMENT PROCEDURE: (45-PPM+ SLUG PRO)
1. Dispense a 6 second shot into a plastic bag and simultaneously start stop watch.
2. 10 seconds prior to the specific system STRING-GEL, provided on the Technical Data Sheet,
begin poking 4" - 12" deep into the rising foam with wire. Repeat at 5 second intervals into a
fresh foam surface until the foam sticks to the wire and reaches a “stringy” bubble-gum like
consistency.
3. Record time when foam reaches “stringy” consistency.
