BASF LAROSTAT HTS 905 is an antistatic agent with the key characteristics of low resistance and long - lasting antistatic performance. Classified as a quat (quaternary ammonium salt), it can be used for internal addition in materials. It is water - soluble, comes in a liquid form, and is stable up to 250°C. This makes it suitable for a variety of applications in different industries.
Efficient antistatic property: Low resistance for fast static dissipation, long-lasting effect to prevent electrostatic damage
Heat stability: Stable at up to 250°C, maintains effectiveness in high-temperature processing
Water-soluble & liquid form: Easy to mix and apply via internal addition or other methods
Broad application scope: Quaternary ammonium salt type, suitable for engineered thermoplastics, flexible PVC, PP, textiles and dust control
Plastic industry: For engineered thermoplastics & flexible PVC; prevents static buildup in electronic casings and plastic packaging
Polypropylene processing: Improves antistatic performance of PP pipes, sheets and injection-molded parts
Textile & dust control: Manages static in textiles to reduce dust adsorption; applied to industrial dust control scenarios

Q1: What types of polymers is LAROSTAT HTS 905 compatible with?
A: LAROSTAT HTS 905 is primarily designed for use in thermoplastic polyolefins such as PP and HDPE, and demonstrates good compatibility in engineering plastics including ABS, PS, and certain polyesters. It is not recommended for highly polar or hydrophilic resins like PA or PET without prior compatibility testing.
Q2: How does LAROSTAT HTS 905 achieve antistatic performance in finished parts?
A: It functions via a migratory mechanism — the additive gradually diffuses to the polymer surface during processing and service life, forming a thin conductive layer that dissipates static charges. Performance is optimized under typical ambient humidity conditions and may vary with part geometry, surface area, and exposure environment.
Q3: Is LAROSTAT HTS 905 suitable for applications requiring long-term antistatic effect?
A: Yes — it offers durable antistatic performance due to its balanced migration rate and surface retention characteristics. Long-term effectiveness depends on processing conditions, part thickness, and end-use environment (e.g., temperature, humidity, surface abrasion), but it is formulated to maintain functionality over extended service life in typical industrial applications.
Q4: Can LAROSTAT HTS 905 be used in direct food-contact applications?
A: LAROSTAT HTS 905 is not pre-approved for food-contact use under major global regulatory frameworks. Customers intending to use it in food packaging or processing equipment must conduct full regulatory evaluation and obtain necessary authorizations based on their specific formulation, processing method, and intended application.
