WEYLCHEM Hostapur SAS93 (formerly Clariant) is an anionic antistatic agent, mainly composed of ethylene oxide amine adduct complexes, with a white or light yellow granular appearance and 99% active content. It features the ability to significantly reduce the surface resistance of plastic products, making it widely used in engineering plastic fields such as electronic packaging and electronic appliances. As an internal antistatic agent, it is suitable for polyolefins, nylon and various plastics, providing ideal antistatic effects, dust removal and safe production guarantees. It is a non-hazardous material with a shelf life of one year.
High efficiency & persistence: Reduces plastic surface resistance to 10⁸⁻¹⁰Ω; stable performance, low climate impact
Good compatibility: Compatible with resins, no effect on product processing and usage performance
Multi-functional: Acts as external lubricant for PVC, PS & thermoplastics; excellent release & flow improvement
High temperature resistance: Low volatility at high temps; suitable for high-melting thermoplastics (max 400°C)
Polyolefins (PE, PP): Films, sheets, containers, packaging bags, mining dual-resistant mesh belts
Nylon products: Nylon shuttles, PP fibers and related items
Various plastics: PVC, PS, HIPS, ABS/SAN, PC, PET, PBT, POM, PA, TPU, PU, EVA, etc.
Electronic industry: Electronic packaging & appliances for safe production

Q1: What is the primary function of Hostapur SAS93 in polymer formulations?
A: Hostapur SAS93 is an anionic antistatic agent designed to reduce surface resistivity and dissipate static charge in thermoplastic polymers during processing and end-use. It functions by migrating to the polymer surface and attracting ambient moisture to form a conductive layer.
Q2: Which polymer systems is Hostapur SAS93 most commonly used with?
A: It demonstrates good compatibility and performance in polyolefins (e.g., PP and HDPE), ABS, PS, and certain engineering thermoplastics. Performance may vary depending on polymer polarity, melt temperature, and processing conditions.
Q3: How does processing temperature affect the performance and stability of Hostapur SAS93?
A: Hostapur SAS93 exhibits thermal stability suitable for standard extrusion and injection molding processes. Prolonged exposure above 230 °C may accelerate migration or degradation, so optimal dosing and residence time control are recommended for high-temperature applications.
Q4: Is Hostapur SAS93 suitable for applications requiring low extractables or food-contact compliance?
A: While Hostapur SAS93 is not specifically certified for food-contact use, it is widely employed in non-food industrial packaging and technical components where antistatic performance and low volatility are priorities. Regulatory approval must be verified case-by-case per intended application and regional requirements.
Q5: What is the typical dosage range for effective antistatic performance?
A: Dosage depends on polymer type, required surface resistivity, and processing method, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—optimized through formulation trials.
