Armacell s patented r-PET technology
of producing PET foams, made of 100%
recycled PET.
LIGHTWEIGHT CORE FOR STRONG STRUCTURES
ArmaForm CoreArmaForm Core
Armacell offers a wide range of innovative and eco-friendly structural foam cores
combining lightweight and high mechanical strength in conjunction with residual
flexibility and maximum service life. Made entirely of recycled PET bottles,
ArmaForm Core is sustainable, 100% recyclable alternative to legacy materials.
The trend of designing environmentally-friendly composite
structures which are light, strong and recyclable has led industrial
designers, specifiers and composite manufacturers to accelerate
the substitution of conventional core materials such as Balsa, SAN,
PUR or PVC with our PET foam cores in a wide range of applications
as diverse as wind turbine blades, train floors and truck bodies,
building envelopes, boat hulls and surfboards.
