Pressure Sensitive Adhesives Based on Butyl Rubber
Application:
Butyl-based pressure-sensitive adhesives use recycled butyl rubber materials, cured with sulfur compounds, in double-glazed window and door manufacturing industries. In addition, they are used as pressure-sensitive adhesives for use in polyethylene foams to insulate car doors.
Product Introduction:
These adhesives include Butyl IIR rubber or Polyisobutylene-PIB. Butyl rubber (IIR) is produced by cationic copolymerization of isobutylene in solution with a small amount of isoprene (up to about 3%). It was produced and used industrially since 1942. This rubber is used in cases where low permeability against oxygen, ozone
and chemicals is desired. This tire is the cheapest special tire.
Technical Specifications:
In the process of making these adhesives, 7-8% of butyl rubber is used as a raw
material. Other materials used in the formulation of these adhesives include: paraffin oil, poly-isobutene, filler, hydrocarbon resins, and finally 45% of recycled rubber is used in the formulation of these adhesives. In the manufacturing process of all these products, first the powdered butyl rubber is charged inside the kneader, then it is placed at a temperature of 180 ºC for two hours by adding additives for devulcanization, and finally it is rolled.
Advantages:
* Thermal resistance of adhesives, tolerance of high and low temperature conditions
* Adequate viscosity and workability of the glue
* The amount of penetration and maintaining proper adhesion and flexibility in different temperature conditions
