Sponge pulling agent DP-1022 is a multifunctional reactive additive that can be effectively used in many polyurethane foam formulations to enhance the physical properties of sponges such as tensile properties and tear strength. In conventional bulk foam, the stabilizer can prevent the foam from cracking easily in medium and low density formula. Moreover, it can help to lower the isocyanate index and reduce the amount of auxiliary foaming agent needed.
Main features and advantages
• Sponge tension agent DP-1022 provides excellent foaming process and bubble stability at the dosage of 0.5-1.5. The formula only needs to be adjusted with a small amount of catalyst (5-10% caprylate Ya tin is recommended).
• Can also partially or completely replace auxiliary foaming agent in bulk foam formulation
• The process performance of DP-1022 can control the TDI index of traditional bulk foam in the range of 95-100 at 1-2 dosage
• Foam manufactured with A TDI index of 95 can reduce the hardness (25%IFD) of foam manufactured with a TDI index of 100 by 50%. When the TDI index is 95-100, the physical properties of foam are similar to those made with many traditional TDI indexes
• When TDI index is in the range of 105-110, DP-1022 cannot change the technological performance of foam, but it can improve some physical properties of foam.
