Omnia Plastica Akulon® PET Arnite Omnialite
Categories:	Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET); Polyethylene Terephthalate (PET), Unreinforced
Material Notes:	Arnite is a relatively new semi-crystalline polymer developed for technical applications. It is suitable for mechanical parts which require dimensional stability and a low friction coefficient. Omnialite is a modified PET designed to provide a higher shock resistance than Arnite by reducing the E-modulus. Features: Low friction coefficient Dimensional stability both at temperature and humidity Compressive strength even at low temperature Excellent machinability High fatigue resistance Colour: natural Weak Point: The material is very stiff so the shock resistance is not high. It is possible to modify it with the addition of other polymers but this operation is done to the detriment of such characteristics as stiffness, compressive and flexural strength which are the typical features of PET. Application: Mechanical: thanks to its low friction coefficient it is particularly suitable for sliding blocks, slide ways, bearings, guides, etc. Its dimensional stability makes it an excellent choice for precision parts where tight tolerances must be maintained both in moist and hot conditions. Food contact: it is physiological inert and extensively used in the food industry. Electrical: the excellent electrical features (stable in the long run) make PET suitable for insulators and other electrical components. Chemical: good resistance to acids and chlorine solutions.
