Polyurethane rigid foam is the core in these kinds of panels. A
special feature of polyurethanes is their method of production.
Generally, metering and mixing four or more streams of liquid
components containing polyurethane precursors at the processing
stage produce polyurethanes. Thus, the final, high molecular weight
polymer is normally manufactured by the manufacture of Sandwich
Panel who has a PU sandwich panel production line. In the
production line of sandwich panel, one section is dedicated to
performing this process, called “PU Foaming Machine” or “Metering
Machine”.
advantage
1.Polyurethane sandwich panel has good fire resistance
2.Wide range of temperature
3.Fast and convenient installation, short construction period, good
comprehensive benefits
4.Excellent thermal insulation. Thermal conductivity of panels with
polyisocyanurate foam core is λ = 0,022 W/m*K.
5.Excellent protection against weather conditions, maintaining
properties and appearance for many years. When coating is properly
selected according to local 6.conditions, several years’ durability
of panels can be reached without any problem.
7.Complete seal against precipitations, snow and dampness.
Perfectly finished joints ensure complete waterproofness for many
years, if installation standards are followed.
peculiarity
The high flexural bearing capacity of the polyurethane wall panel
makes the wall have better mechanical properties and thermal
insulation properties, while reducing the need for auxiliary steel
structure.
Simple construction: polyurethane sandwich plate has the
characteristics of standardized production and on-site assembly,
convenient installation, can improve the construction efficiency.
Corrosion resistance: The panel of polyurethane sandwich plate has
good corrosion resistance, can resist the erosion of acid, alkali,
salt and other corrosive media, and is suitable for use in harsh
environments.
