Arnite® TV4 660 SN

Technical Datasheet | Supplied by DSM
Arnite® TV4 660 SN by DSM is a flame retardant polybutylene terephthalate and polycarbonate grade (PBT/PC) reinforced with 30% glass fiber. It is suitable for processing by injection molding. Offers durability, excellent dimensional stability, high thermal and oxidative stability, good color-stability, high stiffness, good wear resistance, low coefficient of friction and low moisture absorption. Arnite® TV4 660 SN provides high crystallinity to ensure rapid cooling times, outstanding creep properties and excellent dielectric strength at elevated temperatures. Arnite® TV4 660 SN shows resistance against heat, aliphatic hydrocarbons, motor vehicle fuels, oils and greases, dilute acids and bases, detergents and salt solutions. Meets ISO 1043 for PBT.
