Hostastat HS 1 is an antistatic agent for plastic materials.
Hostastat HS 1 is an alkane sulfonate which provides highly effective antistatic properties to thermoplastic polymers.
General information of Hostastat HS 1:
Hostastat HS 1 is incorporated into plastics as an internal antistatic agent or applied as an external antistat to avoid the negative effects of electro-static charges (e.g. attraction of dust, static discharge, splashing of printing inks).
Benefits of Hostastat HS 1:
Hostastat HS 1 is an antistatic agent mainly used in engineering plastics and PVC
Hostastat HS 1 exhibits an outstanding efficiency and provides long term antistatic effect
Applications of Hostastat HS 1:
Hostastat HS 1 is incorporated into plastics to reduce the negative effects of electrostatic charge accumulation such as dust attraction, static discharge and splashing of printing inks.
During the processing of thermoplastics, Hostastat HS 1 acts as a flow promoting lubricant and release agent.
Hostastat HS 1 is preferably used as an internal antistatic agent for polar plastics, such as PVC and styrenics.
Where incorporation into the polymer is not possible, Hostastat HS 1 can be applied externally to the surface of the finished article by spraying or dipping.
Therefore Hostastat HS 1 is normally used in the form of a 1 % aqueous solution in conjunction with 0,1 % of a suitable surface-acting alcohol, such as Mowiol 10 – 74.
Physical Properties of Hostastat HS 1:
Hostastat HS 1 has a good solubility in water.
Melting Point: ca. 220 °C (396 °F)
Alkane sulfonate: ≥ 90 %
Sodium sulfonate ca.: 5 %
Packaging and Handling of Hostastat HS 1:
Hostastat HS 1 is also available in other physical form.
Pills form may contain traces of brownish or greyish granules which have neither influence on the properties nor on the usability of Hostastat HS 1.
Storage of Hostastat HS 1:
Minimum shelf life of Hostastat HS 1 is 2 years from the date of shipping when properly stored.
Partially emptied containers of Hostastat HS 1 should be carefully resealed immediately after use.
Protect Hostastat HS 1 from moisture.
Hostastat HS 1 should be stored dry and at room temperatures and processed immediately after opening the packaging.

Hostastat HS 1 acts as an internal antistatic & release agent and flow promoting lubricant.
Hostastat HS 1 possesses an outstanding efficiency.
Hostastat HS 1 reduces the negative effects of electrostatic charge accumulation such as dust attraction, static discharge and splashing.
Hostastat HS 1 shows compatibility with thermoplastics and polar plastics like PVC and styrenics.
Hostastat HS 1 has a minimum shelf life of 2 years.
Hostastat HS 1 acts as an internal antistatic agent, flow promoting lubricant and release agent.
Product range of Hostastat HS 1:
Hostastat HS 1, a sodium alkane sulfonate, is supplied as
> Hostastat HS 1 FF (free flowing), pale yellow fine grain
> Hostastat HS 1 Pills, yellowish granules
> Hostastat HS 1 Pills Zn, yellowish granules coated with Zn-stearate as an anti tacking agent to prevent sticking of the granules
Hostastat HS 1 has the appearance of light yellow particles.
Due to the special production process HS 1 does not contain chloride ions.
Storage of Hostastat HS 1:
When using HS 1, special care should be taken that the product is highly hygroscopic.
Hostastat HS 1 is well known that the effect of internal antistatic agents basically depends on the molecular structure, which determines the important properties of antistatic agents such as polarity and mobility.
The long carbon chain in the Hostastat HS 1 molecule provides mobility to polar plastics, while its polar groups provide hygroscopicity, ie it binds moisture necessary to form a conductive film.
The ionic character of the polar groups results in the high conductivity of the Hostastat HS 1 surface film to bind moisture.
In addition to the chemical composition of the antistatic agent, processing methods and ambient temperature can also affect the speed and effectiveness of the antistatic agent's action.
The glass transition temperature of the plastic also has an influence on the antistatic effect.
For those polymers with glass transition temperatures well above room temperature, the antistatic agent does not migrate continuously over the life of the article.
Hostastat HS 1 is particularly suitable for use as an internal antistatic agent for polar plastics.
In those cases where it cannot be added directly to the polymer, Hostastat HS 1 can be sprayed or impregnated onto the surface of the article as a 1% aqueous solution.
Hostastat HS 1 is an external lubricant in PVC, PS and thermoplastic engineering plastics, and has excellent mold release and flow improvement effects.
The addition amount of Hostastat HS 1 is 0.1-2.0%.
Hostastat HS 1 has extremely low volatility at high temperature, so it is commonly used as a Processing aids for high melting thermoplastic engineering plastics.
