Product Description

Hostaform electrically conductive acetal materials.


Volume resistivity
The volume resistivity of Hostaform is ρD= 1012 Ω· m for all grades, except for the high-impact and electrically conductive materials; it is therefore largely unaffected by the presence of additives.
Hostaform C 9021 ELSX and EC270TX have a considerably lower volume resistivity. This is due to the formation of a current bridge by the electrically conductive carbon black. Destruction of the carbon black morphology and/or strong orientation of the carbon black particles can impair the current bridge and allow volume resistivity to increase. Selection of adequate wall thickness will counteract this; in addition low injection rates and high mould wall temperatures should be preferred in processing Hostaform C 9021 ELSX and EC270TX.

Surface resistivity
Surface resistivity gives an indication of the insulation resistance across the surface of a material. The dependence of this value on humidity and surface contamination must be taken into account. In the case of Hostaform, it is appreciably lower than that exhibited by hydrophilic polymers such as certain polyamides.The surface resistivity of most Hostaform grades is in excess of 1014 Ω. Antistatic modification reduces this to 1013 Ω, while in the case of C 9021 ELSX and EC270TX the value is lowered even further to 103 Ω.The surface resistivity of C 9021 ELSX and EC270TX and also its volume resistivity – can be influenced by processing parameters and moulded-part design.Therefore the electrical properties have to be controlled at the moulded part.

In the case of C 9021 ELSX, EC 270 TX, the loss of toughness associated with the electrically conductive carbon black content is partially offset by incorporating an elastomer component.
In drop tests, the decline in toughness of the reinforced and filled grades as compared with unreinforced grades is less pronounced than in the impact and notched impact strength tests. This is the reason why mouldings produced from these grades have adequate design strength, even under impact stress


HOSTAFORM C9021ELSX
Injection moulding grade with addition of conductive carbon black and elastomer. For parts requiring very low electrical resistance. Processing guidelines in section 3.3.

HOSTAFORM EC270TX
Similar to C 9021 ELSX but with higher toughness level.

HOSTAFORM EC140XF
Conductive injection moulding grade with improved resistance to fuels, especially hot diesel.
