Blankenhain/Thuringia – GRAFE Polymer Technik GmbH is one of the
most innovative partners to the plastics processing industry. The company from
Thuringia is presenting its latest material development at the FAKUMA: a
permanently antistatic compound for the manufacture of safety helmets. The
primary objective in developing this material was to meet the requirements of DIN
EN 397, since protecting the health and safety of people is of highest priority.
Safety on construction sites is of top priority, particularly in hazardous areas. Safety helmets are one of
the most important pieces of protective equipment in the construction and related industries. DIN EN
397 states that safety helmets must be worn without exception at work and during all activities where
falling, suspended, thrown, or blown objects may present danger. The purpose of safety helmets is to
limit, or better still, avoid danger. To this end, helmets must be resistant against thermal, chemical
and climatic influences and should withstand both elastic and plastic deformation. In testing, helmets
are exposed to very low (down to -10 °C) and very high temperatures (up to 50°C), and are subjected
to a ball drop and penetration test. In this test, the helmets are examined for penetration resistance
and safety upon impact with pointed or rounded objects.
Up until now, permanently conductive materials have only been produced in standard black. Safety
helmets in other colors were not electrically conductive and had therefore no antistatic properties. The
newly developed, permanently antistatic PP compound from the GRAFE Group allows the
manufacture of colored, electrically conductive helmets. The PP compound is available in the
following vibrant colors from GRAFE’s Colorstat® series: blue, yellow, white, red and brown. The PP
material was especially developed for lightweight designs. Using 2K injection molding, additional
design elements can be added. These may include, for example, plastic elements that light up in the
dark without requiring additional light sources. Let’s remember: safety helmets can save lives.
