Polyisobutaattieristeillä

Polyisobutaattieristeillä, commonly known as polyisobutylene (PIB) insulation, refers to the use of polyisobutylene as an insulating material. Polyisobutylene is a synthetic rubber polymer produced by the polymerization of isobutylene. It is known for its excellent air and moisture barrier properties, low gas permeability, and good flexibility, even at low temperatures.

In insulation applications, polyisobutylene is often used as a component in sealants, adhesives, and coatings. It can also be manufactured into insulating films or membranes. Its primary advantage is its ability to prevent the passage of air and water vapor, making it effective in applications where moisture control is crucial, such as in building envelopes or packaging.

Polyisobutylene insulation is valued for its durability and resistance to degradation from UV radiation and ozone. These properties contribute to a long service life in various environmental conditions. The material's inherent tackiness also aids in adhesion, simplifying installation in many contexts. Due to its effectiveness as a barrier material, it finds use in applications requiring airtightness and water resistance, contributing to energy efficiency and structural integrity in buildings. The flexibility of PIB also allows it to accommodate movement and expansion within structures without compromising its insulating capabilities.
