Electret Masterbatch for Melt-Blown Nonwoven

The polymer and melt flow used on the melt-blown line, the charging method installed (corona, hydrocharging or other), basis weight and fibre fineness, the storage and humidity conditions the media will see, and the test protocol your customer specifies decide which grade fits.

The types listed here are the commercial variants Allzone can quote inside this single product identity. They are not stock items and no property value is asserted here — carrier resin, additive loading, colour and let-down ratio are confirmed in the quotation for the exact grade offered.

Filtration efficiency, pressure drop, charge retention and ageing behaviour are properties of the finished media — they depend on your line, your charging step, basis weight and test method, not on the additive alone. This page publishes no such value and makes no performance, protective, medical or health claim. Any figure is taken from producer documentation for the exact grade and confirmed by your own testing.

Tell us the process it runs on — injection moulding, blown or cast film, sheet extrusion, profile extrusion, blow moulding, fibre spinning, melt-blown or spunbond nonwoven — together with the host polymer, the line conditions and the finished article. Grade selection is reviewed against the process, not against a catalogue line.

Additive masterbatches behave differently in different polymers, on different lines and at different throughputs. Any effect claimed by a producer document is treated as a starting point for a line trial on your own equipment, not as a guaranteed result on your article.

This page asserts no numeric specification, no dosage, no performance value, no service life, no origin, no certification, no approval and no availability. Every value that matters commercially is taken from the producer documentation for the exact grade offered and confirmed in writing before order.

Allzone sources this material through producer channels and quotes it per enquiry. The grade is selected against your technical requirement, quantity, documentation need and destination, and is stated in the offer rather than fixed by this page.

Technical data sheet and safety data sheet for the exact grade offered are requested from the producer and shared with the offer. Where a declaration is relevant to your application — food contact, recycled content or any regulatory document — it is confirmed for that specific grade and intended use rather than assumed from this page.

Send the host polymer, the process, the article, the quantity and the documentation you need. Several masterbatches and compounds can be listed in one enquiry and reviewed together rather than split across separate requests.
