The dangers of styrene
Styrene is a viscous liquid that is either clear or yellowish in colour. It is not very water
soluble, but will mix with a number of organic solvents like acetone, ether, methanol,
benzene or toluene. Styrene is used in organic chemical synthesis and also to make plastic
and rubber materials.
The sectors most concerned by styrene are polystyrenes, synthetic rubbers (styrene-butadiene), and unsaturated polyesters and reinforced unsaturated polyesters (reinforced with
glass fibre, for example).

unit for 15 minutes (Figure 6) to
cure the resin. When the laminated
surfboard is taken out of the unit, the
vacuum bag is removed.

set up. A vacuum pump is activated at
one end of the flow mesh, causing the
resin at the other end of the mesh to
migrate (Figure 5). Once the reinforcement is impregnated, the surfboard – still wrapped in the vacuum
bag – is placed inside a UV exposure

The Styrene Free project coordinated
by Rescoll was a technical success on
several counts, since it resulted in:
- the development of a polyester resin
for infusion that meets “surfing”
specifications;
- the application of the vacuum infusion process to the lamination of
surfboards using the above resin;
- a reduction in the use of the consumables usually associated with the
infusion process;
- the creation of a prototype that
meets surfing expectations.
The effectiveness of the product/
process pair was observed during the
laboratory tests and the
prototype fabrication, since there
were no styrene emissions during
processing. This was validated by the
measurements taken by an inspector
from the regional sickness insurance
fund (Carsat) who was called in. In
addition, for the same performance,

the resulting board weighs less than
a standard board, which has both an
economic advantage (less resin used)
and a technical one (better mechanical performance). n

The Styrene Free project was
financially supported by the Aquitaine
Regional Council and the Aquitaine
branch of the French Environment and
Energy Management Agency.

Styrene: What are the risks?
For health:
- Acute risk (brief exposure): headaches, sleepiness, dizziness,
weakness, nasal irritation and problems with coordination linked
to the inhalation of styrene. Eye irritation linked to contact with
styrene.

- Chronic risk (extended exposure): headaches, nausea, dizziness,
feeling intoxicated and problems with coordination linked to the
inhalation of styrene. Eye, nasal and throat irritation linked to
contact with styrene.

Other risks:
- Fire and explosion: linked to the flammability of styrene and its
ability to form explosive mixtures with air above temperatures of
40°C (forms a heat-sensitive explosive peroxide).

• Potentially explosive reaction with oxidants.
• Dissolves certain plastics and rubbers.
