What is DSM's Arnite TV4 261

Today's manufacturing industry is rapidly moving towards smaller, more integrated and smarter, placing unprecedented performance demands on materials. From automotive electronic control systems to smart home appliance structures, from industrial modules to precision connectors, traditional materials often struggle with dimensional stability, electrical safety or impact resistance. If you're having trouble choosing a material for demanding applications, DSM's Arnite TV4 261 (PBT TV4 261) may be just the ticket.

01 | What makes PBT Arnite TV4 261 stand out from the rest?

Multiple levels of electrical safety

In high-voltage components and control modules, electrical stability is a top priority. With an insulation strength of 42 kV/mm, volume resistance of 1E10 Ω-cm, and an arc resistance rating of 5PLC, the Arnite TV4 261 not only meets electrical safety standards, but it also provides protection for high-density cabling and miniaturised modules.

Balanced aesthetics of structural strength and toughness

Compared to traditional ‘brittle’ GF-PBT, TV4 261's mechanical data is quite convincing - tensile strength of 145 MPa, tensile modulus of 9750 MPa, simple beam notch at 23°C, and impact strength of 9.5 kJm. Impact strength of up to 9.5 kJ/m² at 23°C. Even at temperatures as low as -30°C, the unnotched impact toughness remains at 60 kJ/m², demonstrating excellent resistance to low-temperature embrittlement.

Stability is productivity

In injection moulding, Arnite TV4 261 continues to perform well in complex cavity configurations and multi-cavity, high-productivity designs with a 30% glass reinforcement system and low dimensional change of 0.6%, dramatically reducing reject rates and mould calibration costs.

02 | Typical application areas: not everything, but for the ‘difficult’

Electrical connectors/modules: components requiring high voltage resistance and thermal stability.

Structural supports for household appliances: e.g. iron bases, heat gun housings, long-term heat resistance up to 140°C.

Automotive electrical housings: structural stability under multiple conditions of oil, heat and vibration

Industrial modules/power distribution assemblies: arc resistance and excellent dimensional consistency for precision assembly scenarios
