Why choose butyl rubber to produce waterproofing materials?
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
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.
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).
Excellent water tightness, high saturation, excellent aging resistance, UV resistance and chemical resistance
