Clariant Hostastat FA38 is a light yellow powder antistatic agent with dual functionality—it acts as both an antistatic agent and a lubricant for plastics, and is easy to operate. It can continuously migrate from the plastic matrix to the surface, maintaining long-term antistatic effects. When used together with antistatic agent FE2, it exhibits a synergistic effect to achieve faster antistatic performance. Additionally, it serves as a processing aid, especially effective for improving the surface gloss of PS and ABS products.
Dual functions: Delivers antistatic performance and lubrication for plastics
Long-lasting effect: Continuently migrates to plastic surface to sustain antistatic property
Synergistic compatibility: Works with FE2 to accelerate antistatic results
Multi-role: Acts as a processing aid to enhance surface gloss of PS/ABS products
PE (LDPE, HDPE) & PP: Functions as antistatic agent and processing aid (suitable for BOPP films)
PS & ABS: Serves as antistatic agent and improves product surface gloss
Long-term antistatic scenarios: For plastic products requiring sustained antistatic performance
Multi-functional processing: For plastic processes needing integrated antistatic, lubrication and gloss-enhancing functions

Q1: What types of polymers is Hostastat FA38 compatible with?
A: Hostastat FA38 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 is also suitable for certain engineering thermoplastics where surface resistivity reduction is required without compromising mechanical properties.
Q2: How does Hostastat FA38 achieve antistatic performance in plastics?
A: Hostastat FA38 functions as an internal antistatic agent by migrating to the polymer surface during processing and service life. Its amphiphilic molecular structure enables it to orient at the air–polymer interface, where the hydrophilic moiety attracts ambient moisture—forming a conductive layer that dissipates static charge effectively.
Q3: Is Hostastat FA38 suitable for applications requiring regulatory compliance for food contact or medical devices?
A: Hostastat FA38 is not pre-approved for direct food contact or medical device applications under major global regulatory frameworks. Customers must conduct their own regulatory evaluation—including migration testing and toxicological assessment—based on final formulation, processing conditions, and intended end-use requirements.
Q4: What is the typical dosage range for Hostastat FA38 in polymer formulations?
A: Dosage depends on the base polymer, processing method, and target surface resistivity. Hostastat FA38 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—and often achieves effective antistatic performance within the lower half of this range, especially in thin-walled or high-surface-area applications.
