Introduction

PUF Feature

軽量
Lightweight

PUF is a porous structure
consisting of open cells and
has many air gaps, therefore
is a light plastic material with a density of minimum
15kg/m3.

クッション性
Cushioning
Flexible-PUF has excellent
cushioning properties, thus it
is used in a wide range of
fields such as bedding,
furniture, automobile seats,
and industrial parts.
応力緩和性
Stress relaxation
A type of PUF called low-
elasticity foam, is used for
mattresses, pillows, wheel-
chairs, cushions, etc. because it has excellent energy
absorption and good pressure
dispersion.
衝撃吸収性
Shock absorption
PUF can disperse impact
energy by deforming against
strong shock, thus it is used
as shock absorbing materials
so on.
通気性
Breathability
The open-celled PUF which
has breathability, is available widely from low to high air
permeation, according to the
purpose of use.
難燃性
Flame-retardant
A type of PUF which is hard to spread fire meets the flame
retardance regulation about
interior materials for auto-
mobiles, railway vehicles, and interior materials for aircraft.
シール性
Sealability
The low air-permeable PUF 
can be used as air seal
materials, and the highly
water-repellent PUF can be
used as water seals.
吸音性
Sound absorption
Since PUF is a porous struc-
ture, the energy of the sound that has penetrated into PUF
is attenuated and PUF exhibits
excellent sound absorbing
capability.
加工性
Processability
PUF has capability for various processing such as slicing, cut-ting and punching.
