to decrease the incidence of pressure sores. Low-temperature
flexible ski boot shells can be injection moulded from
polyester or polyether TPUs. The abrasion resistance of TPU
has had a great impact on the design of high-performance
wheel and bearing structures of in-line skates.

FIBRE REINFORCED COMPOSITES IN
LEISURE PRODUCTS
Heitz E
Parts made from fibre composites have been used in leisure
and sports products for a long time. Their low weight in
conjunction with the ability to absorb high forces means
preference is given to fibre-reinforced plastics. Ingenious
designs and special production procedures are used to
produce high-tech products for this area of application.
Bicycle production is increasingly making use of parts made
from fibre composites based on aeronautical engineering
principles; high standards found in this industry have now
been transferred to the civilian and leisure sectors. Translation

Constructing a range of sports and safety surfaces is easier,
quicker, and cheaper using a new impact absorbing asphalt
based on reclaimed rubber. Traditional surfaces have been
achieved by laying a conventional asphalt to provide a
stable and level base upon which to lay a resin-bound rubber
shock pad that provides the impact absorbing properties of
the structure. A sand-filled synthetic grass carpet is laid
over the shock pad to provide the playing surface. By
developing an impact absorbing asphalt the two processes
are reduced to one which is considerably cheaper.

Metallocenes, a relatively new class of polymer catalysts,
are reported to be currently among the hottest topics with
material suppliers. But what do resins that use metallocene
catalysts have to offer moulders? Huston Plastics is using
a polyolefin elastomer - Engage from DuPont Dow
Elastomers - to replace a material formerly used to mould
fins used for fly fishing, which deteriorated on exposure
to petroleum. This ethylene octene copolymer material is
produced via Dow’s Insite technology, which includes
both process expertise and metallocene catalysts. Details
are given.

RECYCLING OF AUTOMOTIVE FOAM/FABRIC
LAMINATES BY INCORPORATION INTO
REBONDED POLYURETHANE FOAM
Sims G L A; Angus M W
Manchester,University; UMIST
PU foam waste has, for many years, been manufactured
into rebonded foam for use in energy absorbance
applications such as vibration and sound damping,
sportsground surfacing and carpet underlay. Recent
legislation places more responsibility on manufacturers
to recycle rather than landfill polymeric waste, and is of
major importance for PU components and fabric laminates
used in the automotive industry. An investigation of the
incorporation of polyester PU foam and foam/fabric
laminates into rebonded foam using a prepolymer based
on MDI is presented. Compression and fatigue properties
of rebonded foam formed from granulated PU foam bound
with prepolymer additions of 1-30% were determined in
the density range 50-150 kg m-3. The effect of
incorporating granulated PU foam/fabric laminate
recycled from automotive seat covers into the chip foam
was also assessed. 7 refs.
