| Product Description | ||||
|
ASTALON™ H4000 is the lowest viscosity (ultra high melt flow) grade in the ASTALON™ range and is well suited to extremely intricate or "difficult to fill" injection moulding applications, especially those requiring stress free mouldings for optical and electrical signal transmittance. Offering a balance of transparency, toughness, heat resistance, flame retardancy and processability, typical applications include domestic video and audio discs (compact discs) as well as digital discs for the computer data and program storage field.
