Silane Pex globally by country in 2000

New bimodular materials (PE 100) manufactured by a cascade process, which equips
them with highly cristalline zones of short molecule chains, allowing wall thicknesses
well below the more standard PE’s. They are the reference materials for gas distribution
pipes in Europe today. The term PE 100 indicates the strength this PE (long term
strength of at least 10 Mpa at 20°C over 50 years).

PE 100 set new standards in terms of creep rupture strength, stress crack resistance
and resistance to rapid crack propagation. Sagging and dimensional stability are
however issues for PE100 based pipes at dimensions that exceed 65mm (Silane xlinking
does resolve the sagging issue). Their higher stiffness is limiting their use in smallerdiameter
waterpipes for floor-heating.
