Clariant Hostastat FE 20 is a fatty acid ester-based antistatic agent derived from renewable fatty acids, designed for thermoplastic polymers. It delivers high-efficiency internal antistatic performance, effectively balancing and reducing static charge on polymer surfaces. Beyond antistatic functions, it also acts as an internal lubricant and processing aid during PVC processing, with no fogging at conventional addition levels (0.5%-2%).
Renewable source: Based on renewable fatty acids, eco-friendly compliant
Multi-functional: Integrates antistatic, internal lubrication and processing aid functions
High compatibility: Excellent performance in PVC (semi-rigid/flexible) and styrenic polymers
Fog-free: No fogging at recommended dosage (0.5%-2%)
Semi-rigid & flexible PVC: Delivers internal antistatic performance and processing improvement
Styrenic polymers: Effective static charge reduction on polymer surfaces
PVC processing: Acts as internal lubricant to optimize processing efficiency
Eco-friendly thermoplastics: Suitable for fog-free antistatic requirements

Q1: What types of polymers is Hostastat FE 20 compatible with?
A: Hostastat FE 20 is primarily designed for use in polyolefins such as polypropylene (PP) and polyethylene (PE), including both homopolymers and copolymers. It demonstrates good compatibility and dispersion in these non-polar matrices, and may also be evaluated in certain engineering thermoplastics where surface resistivity reduction is required.
Q2: How does Hostastat FE 20 achieve its antistatic effect?
A: Hostastat FE 20 functions as an internal antistatic agent by migrating to the polymer surface over time, where it attracts and binds atmospheric moisture. This forms a conductive layer that dissipates static charge, thereby reducing surface resistivity and minimizing electrostatic discharge risks during processing and end-use.
Q3: Is Hostastat FE 20 suitable for applications requiring low extractables or food contact compliance?
A: Hostastat FE 20 is not specifically formulated or certified for food-contact applications. Customers requiring regulatory compliance—such as for food packaging or medical devices—should consult Clariant’s regulatory team for available documentation and suitability assessments based on their specific formulation and processing conditions.
Q4: What is the typical dosage range for effective antistatic performance?
A: Effective dosage generally ranges from 0.1% to 2% by weight, depending on the base polymer, processing method, desired surface resistivity level, and environmental conditions such as humidity. Optimization is recommended through small-scale trials to balance performance, cost, and potential impact on mechanical properties or clarity.
