Arnite® TV4 461

Technical Datasheet | Supplied by DSM
Arnite® TV4 461 by DSM is a polybutylene terephthalate + polyethylene terephthalate alloy (PBT + PET) reinforced with 30% glass fiber. 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 461 provides high crystallinity to ensure rapid cooling times, outstanding creep properties and excellent dielectric strength at elevated temperatures. Arnite® TV4 461 shows resistance against heat, aliphatic hydrocarbons, motor vehicle fuels, oils and greases, dilute acids and bases, detergents and salt solutions. Used in automotive applications. Meets ISO 1043 for PBT.
