Name: Mitsubishi Chemical METABLEN P-551A Acrylic Processing Aid
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Mitsubishi Chemical METABLEN P-551A Acrylic Processing Aid

Enhances melt strength and melt elasticity during extrusion of acrylic (PMMA) resins.
Improves surface gloss and reduces die build-up in high-speed sheet and profile extrusion.
Provides excellent thermal stability without discoloration at typical PMMA processing temperatures (180–230 °C).
Offers good compatibility with standard methyl methacrylate homopolymers and copolymers.
Enables stable extrusion output with reduced surging and improved dimensional consistency.

Typical Applications Of Mitsubishi Chemical METABLEN P-551A Acrylic Processing Aid

Extruded PMMA sheets for signage, lighting diffusers, and architectural glazing.
Continuous extrusion of acrylic profiles including trim, framing, and decorative moldings.
Co-extrusion layers requiring enhanced interlayer adhesion and surface integrity.
High-gloss acrylic injection-molded components where surface defect minimization is critical.
