General FAQ

Methyl Methacrylate (or more commonly referred to as MMA monomer) is colourless liquid that is the basis material for Polymethyl Methacrylate (SUMIPEX® PMMA).

Polymethyl Methacrylate (SUMIPEX® PMMA polymer) is a kind of thermoplastic resin, which is flammable and also soluble in an organic solvent.

*Note: Data obtained from various available sources and to be used as reference guide only.

The SUMIPEX® PMMA polymer finds its use across various industries and applications owing to its favourable properties like aesthetics, scratch resistance and thermal resistance. SUMIPEX® PMMA is extensively used in these industries:

Yes, it is. In fact it is one of the few plastic materials that can be reversed into its original monomer liquid form through a cracking process. Once reversed into the original liquid form, it can be reused for other applications.

Product FAQ

SUMIPEX® PMMA is manufactured by free radial vinyl polymerisation process using MMA monomer.

SUMIPEX® PMMA (density= 1.19kg/m3) is a much lighter option as compared to glass (density=2.5kg/m3).
The optical property of SUMIPEX® PMMA (Total light transmittance=92.6%) is also higher as compared to glass (Total light Transmittance=90.2%).

SUMIPEX® is also known as acrylic glass, a good alternative to glass as it is safer option due to its shatter proof characteristics.

SUMIPEX® molding materials are available in a variety of different grades. Each grade possesses the special characteristics unique to acrylic polymers, thus allowing usage in a wide range of applications. SUMIPEX® can be chosen from numerous selections in accordance with the particular desired usage.

SUMIPEX® is made to have more durability properties compared to other transparent plastics.
