JM’s Polyisocyanurate foam, known as TRYMER® PIR, is a closed-cell, high-performance insulation for use in industrial and commercial applications. TRYMER PIR is manufactured into bunstocks to be fabricated into the appropriate shapes and sizes for pipes, vessels, equipment, and duct applications.
Johns Manville AP™ Foil25 Polyiso Continuous Insulation is a 25-psi compressive strength board which consists of a uniform closed-cell polyisocyanurate foam core bonded on each side to a foil facer.
15 wrz 2016 · Introduction. The current work is aimed at better understanding of the viscosity characteristics of isocyanate (NCO)-based crosslinkers, an essential parameter in their production and processing.
This guideline covers the installation of the Dyplast insulation system chilled water piping, tanks, vessels and equipment. The Dyplast System consists of ISO-C1 Rigid Polyisocyanurate Insulation and zero- or low-perm vapor retarder film/tape, and appropriate jacketing.
Polyisocyanurate boards (also known as PIR or polyiso) and rigid polyurethane foam are highly durable and best-in-class options for thermal insulation in the construction industry and in appliances.
POLYISOCYANURATE ADVANTAGES. Greater dimensional stability over a wider service temperature range. Low thermal conductivity. Lightweight and easy to install. Wide choice of adhesives and coatings can be used for bonding.
