Application of sponge tensile agent in polyurethane foaming

Sponge tensile agentDP-1022

Product Description

Sponge tensile agentDP-1022 is a multifunctional reactive additive that can be effectively used in many polyurethane foam formulations to enhance the tensile properties of the sponge and tear. Strength and other physical properties. In traditional bulk foam, this stabilizer prevents the foam from cracking in medium and low density formulations. Furthermore, it can help lower the isocyanate index and reduce the amount of auxiliary blowing agent required.

Main features and benefits

•When the dosage is 0.5-1.5 parts, sponge tensile agent DP -1022 provides high-quality foaming technology and bubble stability, and the formula only requires adjusting a small amount of catalyst (it is recommended to reduce 5-10% of tin octoate)
•Can also be partially or fully substituted in bulk soft foam formulas Auxiliary foaming agent
•At 1-2 servings, DP-1022 provides Process performance can control the TDI index of traditional large foam within the range of 95-100
•Foam made with a TDI index of 95 can be compared to When the TDI index is 100, the hardness (25%IFD) of the foam produced is reduced by 50%. When the TDI index is 95-100, the physical properties of the foam are similar to those made with many traditional TDI indexes
• When the TDI index is in the range of 105-110, DP-1022 It cannot change the process performance of the foam, but it can improve some physical properties of the foam.

Sponge pulling agent DP-1022

product description

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.
