Category

3D Printing Materials

Synonyms

Poly(methyl methacrylate), Methyl methacrylate resin, Perspex

Description

PMMA is a transparent plastic that offers incredible strength and stiffness and can be optically clear. This transparency makes it easy for advanced vision systems or employees performing physical visual inspections to analyze and monitor food product quality throughout transportation.

IUPAC Name

Poly(methyl 2-methylpropenoate)

Molecular Weight

average Mw ~350000 by GPC

Molecular Formula

[CH2C(CH3)(CO2CH3)]n

InChI

1S/C5H9O2/c1-4(2)5(6)7-3/h1-3H3

InChI Key

PMAMJWJDBDSDHV-UHFFFAOYSA-N

Melting Point

160 °C (320 °F; 433 K)

Density

1.18 g/cm³

Solubility

H₂O: insoluble

Application

PMMA is often used to store milk and other dairy products, oils, and feed for animals. Acrylic is also used to create mixing bowls, where transparency can aid mixing and other cooking process applications. PMMA is BPA-free and non-toxic when solid, and it’s so biocompatible that acrylic is frequently used in dentures and cavity fillings.

Storage

room temp

Chemical Formula

(C5O2H8)n

Feature

The limitations of acrylic include poor impact resistance and limited heat resistance, weakness against attacks by organic solvents, and susceptibility to cracking under pressure due to poor wear and abrasion defense. It’s important to consider these downsides when choosing whether or not to use PMMA for food and beverage packaging purposes.
