描述
PLEXIGLAS 7H PMMA Molding Compound Extrusion Grade High Melt Strength
Material: PMMA (Acrylic)
Process: Extrusion
MVR: 1.4 cm³/10min
AMECA: Listed
Packing: 25kg bag / 500kg box
PLEXIGLAS 7H is a high melt strength PMMA molding compound specially designed for demanding extrusion applications. With an extremely low MVR of 1.4 cm³/10min at 230°C/3.8kg, it delivers exceptional melt strength for stable processing of large profiles, sheets, tubes, and multi-skin sheets. It combines the familiar properties of PLEXIGLAS molding compounds — 92% light transmission, outstanding weather resistance, high mechanical strength, surface hardness, and mar resistance — with high heat deflection temperature (Vicat 103°C, HDT 100°C at 0.45 MPa) and AMECA listing.
PLEXIGLAS 7H is particularly suitable for extruding optical and technical profiles and sheets. Typical applications include sheets, tubes, multi-skin sheets, coextrusion of window profiles, and similar extrusion applications requiring high melt strength and structural integrity. Processable on extruders with 3-zone general purpose screws for engineering thermoplastics at melt and die temperatures of 220-260°C.
