Material Notes:
OROGLAS HFI-7 is a medium impact grade that in addition to the improvement in impact resistance provides superior flow which contribute to reduce the cycle time and improve demolding.Key features : impact resistance: up to 7 times more impact-resistant than standard acrylic easy processing: flow significantly improved which contribute to reduce cycle time by 20 % ( MFI, 230°c/3.8 kg ) = 11 gr / 10 min ( MVI, 230°c/3.8 kg ) = 10.3 ml / 10 min clarity, brilliance and excellent optical properties UV stability Typical applications : OROGLAS HFI-7 is the material of choice when toughness and increased flow are required. OROGLAS HFI-7 can be injection molded or extruded to produce parts for the following fields: building, lighting, appliances, information technology and business machines.ISO data provided by the manufacturer, Arkema.Arkema, formed in 2004, was formerly Atofina Chemicals and before that Elf Atochem.
