Arnite® TZ4 254 S

Technical Datasheet | Supplied by DSM
Arnite® TZ4 254 S by DSM is a flame retardant polybutylene terephthalate + polyethylene terephthalate alloy (PBT + PET) reinforced with 25% glass and mineral 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® TZ4 254 S 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 PBT+PET.
