RUBBER ACCELERATOR MBS

Leave a comment , , ,
  • Product Name: RUBBER ACCELERATOR MBS
  • Other Name: RUBBER ACCELERATOR NOBS
  • CAS NO.: 102-77-2
  • Chemical Name :N-Oxydienthylene-2-benzothiazole sulfenamide
  • Molecular Formula :C11H12N2S2O
  • Molecular Weight: 252.36
  • EINECS NO.: 203-052-4

Specifications:

Appearance Light   yellow granular
Initial M.P. oC≥ 80.0
heating loss %≤ 0.50
Ash%≤ 0.30

Properties: Light yellow brownish powder, grain. Bitter taste,Specific gravity 1.34-1.40, soluble in benzene, acetone, methyl alcohol; insoluble in water.

Application: An excellent delayed accelerator. The performance is similar to that of CZ displaying better scorch safety. Widely apply in NR, IR, SBR, NBR and EPDM. Apply alone or with those vulcanization accelerators such as thiurams, guanidines and dithiocarbamates to improve the activity, mainly use in manufacture of tires, shoes and belts, non-blooming. Not recommended to apply in beverage and food containers because of the bitterness of the product after vulcanization.

Package: 25kg in kraft paper bag with PE bag inside,.

Storage: Keep in a cool, well-ventilated place.

Properties: Grayish-white powder(granule)No taste, no poison. Densiy is 1.08–1.19. Soluble in acetone, ethyl acetate, benzene, alcohol, slightly soluble in CCl4; Insoluble in water and gasoline.

Application: Used as a secondary accelerator with thiazoles and sulphenamides in NR and SBR compounds. Exhibits better storage stability compared to thiuram and dithiocarbamates but is not so active. DPG can be used in latex as secondary gelling agent (foam stabilizer) in the silico-flouride foam process.

Packaging: 25kg plastic woven bag, paper with plastic film bag, kraft paper bag or jumbo bag.

Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended maximum storage life is 2 years when stored under normal conditions.
