Polyisobutylene (PIB)

Product Type  Plastic and rubber raw materials
 
Production and application:

a.Molecular weight dimensionally stable, narrow distribution, low oligomer content, stable performance oligomer content is reduced to ensure long-term stability in the customer products under strong UV irradiation, no excess glue, not flowing, stable bond performance.
B .High environmental protection, no chlorine, low halogen content, low heavy metal content, in line with FDA and European standards.
C. Can provide a series of products, from low to ultra-high molecular weight series products, to ensure customer product development sustainability.
d. a stable supply capacity. raw materials from the integrated base.
E. Polyisobutylene has production and use of experience to provide customers with complete solutions.
f., the high Molecular weight Polyisobutylene is often used in adhesives, rubber, Chewing gum, petroleum industry, etc.

Features:

a. Good insulation performance, cold flow HMW ≈crosslinked rubber not chem bonds / liquid or plastics under load and chemically inert
b. Water and boiling water resistance, completely insoluble in water, gas barrier B200 LDPE / NR
c At room temperature, it is acid and alkali resistant and insoluble in liquid or gaseous bromine and chlorine, insoluble in methanol, ethylene glycol, glycerin, acetone, cyclohexanone, methyl / ethyl acetate; soluble in ether, butyl acetate, Vegetable oils, mineral oils, triphenyl solvents, etc.
d. Maintain elasticity to -50 ° C at low temperature, gradually harden and become brittle, begin to flow and decompose at 180 ° C.
E. Molecular weight distribution is narrow, high purity, low ash content (<100ppm), volatilization Few (<1 ‰)
f. Excellent weather resistance, but UV can cause decomposition, carbon black, antioxidants and stabilizers can be avoided

  Secondary brand Polyisobutylene (PIB) N-50, N-80, N-100, N-150 N-50, which is very close to the authentic brand N-50 can be used in the production of chewing gum, N-80, N-100, N-150 is used in adhesive and roof production
Reasons for the secondary brand in the production of adhesives and roofs : Studinger index is high or low 5-10% (Staudinger index) 40-60 tons / month, continuous supply and can only be sold to end users.
