Polyurethane Delay Catalyst A-300


Chinese name: Catalyst A300

Alias: A300, Catalyst A300, Catalyst A-300, Polyurethane Catalyst A-300, Polyurethane Delay Catalyst A-300, Delay Catalyst A-300, Delay Catalyst, Foam Delay Catalyst, Amine Catalyst A-300, Delayed Amine A-300, Car seat cushion catalyst, car backrest catalyst

NT CAT-300 is a delayed gelation catalyst specially designed for the production of car seat cushion and backrest polyurethane. The production of foam plastic will have good cell opening performance, but at the same time maintain the stability of the foaming formula and will not collapse. For systems that use MDI ingredients, have fast response and slow flow, can improve foam flowability;

NT CAT-300 is mainly suitable for molding high resilience, PUR and PIR discontinuous plates.

Features and advantages:

  1. Delayed cross-linking tertiary amine composite catalyst.
  2. The cross-linking effect of delayed catalyst A-300 is the same as that of A-33 (33% triethylenediamine).
  3. After the foam is lifted, the viscosity increase speed is slowed down and the fluidity is improved. Provide enough time for the foamed raw material to distribute the mold cavity evenly
  4. Suitable for full MDI formula or MDI/TDI mixed formula.
  5. Traditional high-water MDI formula, generally foam will close the cell, use delayed catalyst A-300 to make more open-cell foam plastic, reduce rolling force (such as nozzle) will not cause damage.
  6. The physical properties of the foam plastic products can be maintained for a long time without decay.
  7. Low or non-corrosive, no damage to low carbon steel (such as nozzle)
  8. Amine catalyst A-300 is a delayed crosslinking catalyst specially designed for the production of automobile seat cushion and backrest polyurethane. The production of foamed plastics will be more open-celled, but at the same time maintain the stability of the foaming formula and will not collapse. For the use of MDI-containing components, fast response and slow flow systems can improve fluidity.


Storage and transportation:
