Arnite® TV4 461 KL

Technical Datasheet | Supplied by DSM
Arnite® TV4 461 KL by DSM is a polybutylene terephthalate + polyethylene terephthalate alloy (PBT + PET) reinforced with 30% glass fiber. It is a heat and UV stabilized grade. It is suitable for processing by injection molding. Offers excellent surface properties, 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. 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. Arnite® TV4 461 KL is used in automotive applications such as exterior mirror bases. Meets ISO 1043 for PBT.
