Why choose butyl rubber to produce waterproofing materials?
Butyl rubber
Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" or polyisobutene,ₙ, is the homopolymer of isobutylene, or 2-methyl-1 propene, on which butyl rubber is based. Butyl rubber is produced by polymerization of about 98% of isobutylene with about 2% of isoprene. Structurally, polyisobutylene resembles polypropylene, but has two methyl groups substituted on every other carbon atom, rather than one. Polyisobutylene is a colorless to light yellow viscoelastic material. It is generally odorless and tasteless, though it may exhibit a slight characteristic odor.
Butyl rubber Features :
Low air permeability
Good thermal stability
Good ozone resistance and aging resistance
Excellent shock absorption performance
Good chemical corrosion resistance and water vapor corrosion resistance
Environmental protection:
Butyl rubber is a kind of synthetic rubber, which is synthesized from isobutylene and a small amount of isoprene. It belongs to environmental protection materials.
Construction safety and convenience:
Without machine operation, it can be fully sticky, safe "cold application ", once and for all, and eliminate water channeling.
Strong bonding:
Excellent bonding effect and stability. High creep makes the material have "self-healing function" (actively grow together with the structural concrete and automatically heal the damage below 2mm).
Reliable waterproof:
Excellent water tightness, high saturation, excellent aging resistance, UV resistance and chemical resistance
