hard foam catalyst SMP\/sponge catalyst SMP<\/a><\/h4>\n

Overview:<\/h4>\n

Name: Polyurethane Catalyst SMP<\/h4>\n

Alias: polyurethane catalyst SMP, catalyst SMP, amine catalyst SMP, delay catalyst SMP, hard foam catalyst SMP, sponge catalyst SMP, sponge foam catalyst SMP, low density sponge catalyst SMP<\/h4>\n

\"\"<\/h4>\n

Catalyst SMP is a delayed catalyst for low density sponge or molding, it can increase foam hardness, especially suitable for use in sponges with density in the range of 6-25kg\/kg, and at the same time, it can increase foam hardness by 5-10%;<\/h4>\n

Since SMP increases the hardness of the sponge, it is economically advantageous to reduce the isocyanate index by about 2 to 3 points if the same hardness is to be maintained;<\/h4>\n

Both in MC formulations and in formulations with fillers (CaCO3 and melamine) SMP improves the processability of the foam and reduces cracking;<\/h4>\n
