low-pressure polyethylene
Monolithic single-layer ROSTR® polyethylene sheet extruded from PE-HD with MRS class 100 is one of the basic construction materials with excellent performance characteristics and a wide range of applications.
ROSTR® PE-HD sheets are one of the most cross functional and widely used materials. PE-HD has a higher elasticity than PP-B. PE-HD is distinguished by its ability to maintain performance at sub-zero temperatures down to -50 °C.
Polyethylene PE-HD has a high chemical and corrosion resistance. But it is not resistant to strongly oxidizing agents, ozone, chloroform, aqueous solution of chlorine, nitric acid with a concentration of more than 50%.
ROSTR® PE-HD sheets are suitable for use at both low and high temperatures up to +80 °C.
ROSTR® PE-HD black sheets are protected from the damaging effects of UV rays by means of a special additive "soot" in the raw materials for the production of sheets.
