Butyl rubber, sometimes just called “butyl”, is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber.
What is tire talc used for?
Specially formulated for trouble-free tube installation, Tire Talc reduces folding and sticking which contributes to friction within the tire.
Do latex tubes puncture more?
Latex tubes are much less susceptible to punctures and to pinch flats than butyl tubes, but they are more prone to degradation from the elements.
Are latex tubes safe?
In fact, since latex tubes have so much more puncture resistance (try taking a hammer to latex and butyl inner tubes lying on a table to see for yourself this rather profound difference), they are arguably safer on any kind of wheel where heat buildup isn’t an issue.
