Butyl Rubber (IIR) vs Polyisobutylene (PIB): What Actually Differs
Butyl rubber and polyisobutylene share the same isobutylene backbone, so they are routinely confused — yet only one of them can be crosslinked. This material-science guide explains the molecular difference, why the small isoprene fraction in IIR changes everything, how each behaves under load and over time, and the distinct roles PIB and butyl compounds play in real sealing systems.
Butyl Rubber (IIR) vs Nitrile Rubber (NBR): A Material Comparison
A procurement-focused comparison of butyl rubber (IIR) and nitrile rubber (NBR). Covers the molecular reason NBR resists oil and butyl blocks gas, then compares oil resistance, gas impermeability, weathering, and service temperature side by side. Ends with a decision framework for choosing the right elastomer by application, and where a butyl compound is the correct answer.
Butyl Tape Surface Preparation and Primer Selection Guide
Most butyl tape failures are surface failures. This technical guide covers what actually blocks a butyl bond — moisture, dust, oils, mould release and weathered coatings — then gives a substrate-by-substrate cleaning and solvent table, the dew point and temperature rules that govern site application, and a clear decision framework for when a primer is genuinely required rather than habitually specified.
