Product Name:N-Methylol Acrylamide (NMA)

Product feature:

NMA is a special monomer with two functional groups, they are ethenyl and methylol. Through emulsion polymerization or solution polymerization, thermoplastic polymer may be obtained by comining NMA with many kinds of ethenyl monomer. Because there are functional groups of methylol in the branch chain, this thermoplastic polymer can self cross-link into cross-linked polymer under certain condition.

1、 Directions
  NMA is a special monomer with two functional groups, they are ethenyl and methylol. Through emulsion polymerization or solution polymerization, thermoplastic polymer may be obtained by comining NMA with many kinds of ethenyl monomer. Because there are functional groups of methylol in the branch chain, this thermoplastic polymer can self cross-link into cross-linked polymer under certain condition. NMA polymer can cross-link in the room temperature, the reaction will quicken if adding acid catalyst or heating it, and many matters in it can promote cross-linking efficaciously. The methylol in the NMA can react with many matters under certain condition, such as Acrylamide, Alcohol, Phenol, Hydroquinone and Phosphoric acid, etc., somerections have been used efficaciously. 
  It contains N-Methylol Acryl amide (48% solution), N-Methyl Acryl amide with ultra low free formaldehyole, N-Methylol Acryl amide(98%Crystal).

3、Applications
 NMA is an important chemical raw material, which is used to various high polymers widely, such as coating, adhesive, papermaking aid, etc.; it has huge applicability potential in chemical industry and science study.

 

4、package
 The solution is packed in 200kg plastic barrel and the crystal is in 10kg carton.

 

5、Storage and usage
 It must be kept in cool place, far away heat source and avoid exposure to forceful rays, because heat and rays can lead to polymerize NMA, in the presence of acid or foreign metals especially.Avoid the temperature exceed 28℃.  Even it is kept in good condition, the storage would be best less than 3 months.
   The solution will be made crystal under -10℃, you can dissolve it by heating slowly with warm water bathe, the quality and capacity won’t be affected,   It is forbidden to open lid if the products in the barrel may be polluted. The utensil which is used to get it out and the container must be clean, tweak the lid quickly after get it out every time.

 

6、 Safety and healthy  
 Non-burning and non-burst, toxicity, forbidden to swallow and inhale, wash skin with run water if contact it.
