Halogen-free molding material.


Design engineers grappling with vibration and shock control issues in limited spaces, such as in most precision electronics products, are now said to access the same optimized shock and vibration control properties found in the company's Isodamp elastomers, in a halogen-free, injection moldable formulation, Isodamp C-8002. Isodamp C-8002 thermoplastic A polymer material that turns to liquid when heated and becomes solid when cooled. There are more than 40 types of thermoplastics, including acrylic, polypropylene, polycarbonate and polyethylene.  molding material dissipates energy internally, at the molecular level, virtually immediately, and is said to avoid the design problems of lightly damped compounds (silicones, gels, rubbers, etc.) that require excess sway space for deflection deflection /de·flec·tion/ (de-flek´shun) deviation or movement from a straight line or given course, such as from the baseline in electrocardiography.

 during a shock input. Like other Isodamp elastomers, Isodamp C-8002 is said to minimize vibration amplification at resonance, quickly restoring equilibrium to sensitive, precision systems. The environmentally clean formulation of Isodamp C-8002 is expected to be especially important to companies designing products for Japan and other applications where halogens See Chlorine  and other substances are excluded, according to according to

 the company. Isodamp C-8002 is said to be soft and pliable, yet physically strong, wear-resistant and adhesive-friendly. It is also flame-resistant to UL 94 V-0 and highly dielectric dielectric (dī'ĭlĕk`trĭk), material that does not conduct electricity readily, i.e., an insulator (see insulation). A good dielectric should also have other properties: It must resist breakdown under high voltages; it should not , according to the manufacturer.
