PB Hepworth (PB-R509)

Akoafloor PB-R509 Brown is a random copolymer based on PB-1.  This grade formulated for extrusion into pipe for under floor heating applications.

Main features

Selected by customers for UFH (SHC) ,performance advantages over competitive products; higher productivity ,faster ageing.

Increased flexibility  than PB-1 and PE-RT,higher impact resistance.

Secure connections

All PBR Hepworth  systems use well-established homogeneous welding techniques to join components. The weld becomes the strongest part of the system. Using both socket welding , secure welds ensure the reliability of the whole system.


PBR homopolymers  for the production of flexible pressure piping systems for the growing demand of flexible pipes in surface heating and cooling systems. The elongation at break of PB-R copolymers is also increased significantly. Improved impact toughness properties enable for installation at lower temperatures with less risk of damage. The long term creep rupture performance is equal to PB-1 homopolymers up to 70 °C.

For most application classes according to ISO 10508 the design stress of PB-R is similar to that of PB-1.

PBR homopolymers can be used for mono- and multilayer pipe designs containing oxygen barrier layers such as EVOH.
