Arnite® AV2 390

Technical Datasheet | Supplied by DSM
Arnite® AV2 390 by DSM is a polyethylene terephthalate (PET) grade reinforced with 50% glass fiber. It is suitable for processing by injection molding. It is ideal for PPA replacement and improves dynamic stability of the module at high relative humidity (unlike PA66 and PPA). Offers durability, excellent dimensional stability, high thermal and oxidative stability, high stiffness, low wear-loss, low coefficient of friction and low moisture absorption. Arnite® AV2 390 provides high crystallinity to ensure rapid cooling times, outstanding creep properties and excellent dielectric strength at elevated temperatures. Shows resistance against heat, aliphatic hydrocarbons, motor vehicle fuels, oils and greases, dilute acids and bases, detergents and salt solutions. Meets ISO 1043 for PET.
