  • DABCO 33LVR (A-33) Imported

    DABCO 33LVR (A-33) Imported
    2019-03-27
    label:
    DABCO 33LVR 33% triethylenediamine dipropylene glycol solution, an industrial standard product, is commonly referred to as catalyst A33 or A-33 in China Triethylenediamine, also known as triethylenediamine, has a unique chemical structure It is a cage compound with three ethylene groups attached to two nitrogen atoms The bimolecular structure is very dense and symmetrical It can be seen from the structural formula that there is no substituent with large steric hindrance on N atom, and its pair of empty electrons are easily accessible In foaming system, once the carbamate bond is formed, it will be free, which is conducive to further catalysis
    label: High resilience catalyst Self-crusting catalyst Polyurethane catalyst
  • DABCO 1027, (imported) catalyst 1027

    DABCO 1027, (imported) catalyst 1027
    2019-09-27
    label:
    DABCO 1027 modified ethylene glycol solution of triethylenediamine is a structurally delayed tertiary amine catalyst It can delay the time of milky white, increase the fluidity of the early stage, accelerate the curing of the rear end, shorten the ejection time and improve the production efficiency, improve the fluidity of the system, improve the dimensional stability of the foam, avoid the shrinkage of products, and have a higher catalytic effect on the reaction of polyols and isocyanates It is an amine fast demoulding catalyst developed for polyester and polyether microporous sole and self skin foam system It is an efficient catalyst for polyurethane foam sole, self foam foam and other microcellular foam systems

  • DABCO 33LV

    DABCO 33LV
    2019-09-12
    label:
    DABCO 33LV (import) 33% three ethylene two amine two propanediol solution, suitable for all kinds of polyurethane foam manufacturing It is completely soluble in water and can be completely mixed with polyols, fluorocarbons and tin oxide catalysts Industrial standard products, domestic products are usually referred to as catalyst A33 or A-33 Triethylenediamine, also known as triethylenediamine, has a unique chemical structure It is a cage compound with three ethylene groups attached to two nitrogen atoms The bimolecular structure is very dense and symmetrical It can be seen from the structural formula that there is no substituent with large steric hindrance on N atom, and its pair of empty electrons are easily accessible In foaming system, once the carbamate bond is formed, it will be free, which is conducive to further catalysis For this reason, although three ethylene two amine is not a strong base, it exhibits extremely high catalytic activity for the reaction of isocyanate group and active hydrogen compounds, and is a strong gel catalyst

  • Catalyst DMEA (dimethyl ethanolamine)

    Catalyst DMEA (dimethyl ethanolamine)
    2019-03-27
    label:
    DMEA dimethyl ethanolamine, mild equilibrium catalyst, milky white time is short DMEA is an auxiliary catalyst in polyurethane foam plastics, and DMEA is also a reactive catalyst, which can be used in the formulation of polyurethane soft foam and polyurethane rigid foam There is a hydroxyl group in the molecule of DMEA, which can react with isocyanate group Therefore, DMEA can bind to polymer molecule and not volatilize as easily as triethylamine DMEA dimethylethanolamine is widely used to prepare water-diluting coatings DMEA is also the raw material of dimethylaminoethyl methacrylate, which is used to prepare antistatic agents, soil regulators, conductive materials, paper additives and flocculants It is also used as water treatment agent to prevent boiler corrosion
