Practically indestructible, they also float thanks to a granulated cork
core and hold scent--toughness and features that make traditional plastic bumpers almost obsolete.
The Helix is a result of a four-year deal between Portuguese cork maker Amorim and US bottle maker O-I, using granulated cork
for elasticity and reliability.
Agglomerated cork is obtained from granulated cork
compressed in an autoclave and crossed by a water vapour flow at 350[degrees]C [12, 13].
The secret is in the construction, made out of a super durable poly firehose case, which is darn near indestructible even for obnoxious chewers, then stuffed with pure granulated cork
core for a toughness that surpasses hard bumpers.
