H-4002 Cell Opener | Specially formulated for new rigid polyurethane foam; cell opening rate over 90%; fine cell structure.

Main advantages:

• The open area ratio is as high as 90% or more.
  Excellent opening capability, meeting the dual requirements of open-cell rigid foam products for air permeability and low thermal conductivity.
• Fine pore structure
  While achieving a high open-cell ratio, it maintains a fine cell structure to ensure the mechanical properties of the foam.
• foaming agent
  It can be used stably in conventional rigid foam blowing agent systems without special adjustments.
• Novel Molecular Design
  A unique molecular structure developed specifically for rigid foam opening requirements, resulting in high opening efficiency.
• Recommended dosage is clearly defined.
  The dosage is 0.3-2% of the polyol, and the formula adjustment is simple.

• This product does not stabilize the system during the foaming process and must be used in conjunction with a foam stabilizer (foam leveler).

Typical applications:

• Open-cell rigid polyurethane foam
  Used in open-cell rigid foam products that require breathability or reduced brittleness.
• General rigid foaming agent system
  Suitable for conventional rigid foam blowing agent formulations
