Exton, Pa.-based Biomarine Inc. turned to Milton, Wis.-based Premix Thermoplastics, Inc. when designing the housing for its new 4-hour BioPak 240R Self Contained Breathing Apparatus (SCBA). In addition to military or homeland security actions, the rebreather is also designed for use in mine and tunnel rescue, industrial accidents, Hazmat clean-up, and search and rescue.
The company needed a material capable of handling impact requirements and withstanding continuous temperatures of 190F (88C) without deforming. Also, the material had to withstand 15 seconds of direct flame without burning or showing after glow, and offer surface resistivity of less than 1-e9 ohms to control static buildup. The company chose PRE-ELEC 14- 040, a stainless steel fiber polycarbonate, with impact modification to meet impact properties. Premix supplies it in three colours: black, gray and yellow.
