Application: HBS-A400 is a vegetable based saturated-alkylbis(2-hydroxyethyl)amine of high prrity and low color. HBS-A400 is an internal antistatic additive that can be used in various polymers such as PE, LDPE, PP, SAN, ABS and HIPS. HBS-A400 gives sustained antistatic action and is especially effective in film applications due to its relative fast migration because of its relative short chain.
HBS-A400 is a liquid at ambient temperatures and can be dosed directly into the polymer by using a single or twin-screw extruder. Pigment or color concentrates should be mixed with the antistatic agent prior to extruding. Premixing ensures uniform distribution of HBS-A400 in the resin while HBS-A400 acts as dispersion aid to the pigment color concentrate.

After being mixed into the polymer HBS-A400 continuously migrates to the surface of the finished product where it provides excellent antistatic performance. Due to its relative low molecular weight, HBS-A400 is a relatively fast acting antistatic agent. The saturated alkyl chain gives HBS-A400 a good thermal stability, which makes it especially well suitable for application needing higher processing temperatures. The low color makes HBS-A400 specially suited for more demanding applications.

Some indication for the level applied in various polymers is given below:
Polymer           Addition level (%)
PE               0.1-0.3
PP               0.1-0.3
