Medium Molecular Poly-isobutylene (Industrial Grade)

Packaging and Transportation:
This product doesnt belong to dangerous articles. Medium molecular weight poly-isobutylene can be packaged in 20kg carton with stick resistant lining paper or 50kg fiber drum.

Others:
High molecular material modification, viscosity increasing agglomerate for tensile twisting film, damping grease and so on

Main Applications:
Sealing Compound: Poly-isobutylene is suitable for producing various sealing agents and hollow glass sealing compounds to increase the flexibility and penetrability of products for its excellent features and properties, such as atmosphere resistance, aging resistance, weather resistance and impermeability to water vapor.
Rubber Modification: Poly-isobutylene has excellent aging resistance and plasticity, can be used to modify the rubber. It is now widely used in high-voltage insulating and self-adhesive tapes, and rubber strips and other manufacturing fields.
Paraffin Wax: Poly-isobutylene, after being mixed with paraffin wax or microcrystal wax, can increase its tensile property and enhance the brittleness of its products; especially when used for packaging frozen food, its flexibility and acid resistance can be increased.
Printing ink: Poly-isobutylene can act as the thickener and dispersant when added into printing ink, such as printing pulpy inks, polyethylene cyclic photocopy, printing ink; it can also has a thickening function in the printing ink, to prevent air crack.
Lubricant Grease: Adding in lubricant grease, poly-isobutylene can improve the viscosity and extreme pressure resistance of its products.

Physical and Chemical Properties:
