II. Further Information
Health and Safety:
The material is manufactured to the highest standards but, special requirements apply to
certain applications such as food end-use contact and direct medical use.
Workers should be protected from the possibility of skin or eye contact with molten polymer.
Safety glasses are suggested as a minimal precaution to prevent mechanical or thermal
injury to the eyes.
Molten polymer may be degraded if it is exposed to air during any of the processing and off-
line operations. The products of degradation have an unpleasant odour. In higher
concentrations they may cause irritation of the mucus membranes. Fabrication areas should
be ventilated to carry away fumes or vapours. Legislation on the control of emissions and
pollution prevention must be observed. If the principles of sound manufacturing practice are
adhered to and the place of work is well ventilated, no health hazards are involved in
processing the material.
The material will burn when supplied with excess heat and oxygen. It should be handled and
stored away from contact with direct flames and/or ignition sources. In burning the resin
contributes high heat and may generate a dense black smoke. Starting fires can be
extinguished by water, developed fires should be extinguished by heavy foams forming an
aqueous or polymeric film.
Storage:
The spool s is packed in a bag protecting it from contamination. If it is stored under adverse
conditions, i. e. if there are large fluctuations in ambient temperature and the atmospheric
humidity is high, moisture may condense inside the packaging. Under these circumstances, it
is recommended to dry the material before use. Unfavourable storage conditions may also
intensify the materials slight characteristic odour.
The material is subjected to degradation by ultra-violet radiations or by high storage
temperatures. Therefore the spool must be protected from direct sunlight, temperatures
above 40°C and high atmospheric humidity during storage. The spool can be stored over a
period of more than 6 month without significant changes in the specified properties,
appropriate storage conditions provided. Higher storage temperatures reduce the storage
time.
The information submitted is based on our current knowledge and experience. In view of the
many factors that may affect processing and application, these date not relieve processors of
the responsibility of carrying out their own tests and experiments; neither do they imply any
legally binding assurance of certain properties or of suitability for a specific purpose. The
data do not relieve the customer from his obligation to control the resin upon arrival and to
complain about faults. It is the responsibility of those to whom we supply or products to
ensure that any rights and existing laws and legislation are observed.
