MMA Monomer

Methyl methacrylate (MMA) is an organic compound and a colourless liquid. Primarily used in the manufacturing process of poly methyl methacrylate acrylic plastics (SUMIPEX® PMMA polymer), MMA is also used to produce the co-polymer – methyl methacrylate-butadiene-styrene (MBS), used as a modifier for poly vinyl chloride (PVC). Apart from its use in the manufacturing industry, an alternative application of MMA is as cement used for total hip and knee replacements.

Sumitomo Chemical Asia (SCA) is one of the leading manufacturers of Methyl Methacrylate Monomer (MMA-m) in Asia. We produce MMA-m by using the C4 Direct Oxidation process.

C4: Direct Oxidation Process

MMA-m, besides its use in large quantities as raw material for manufacture of PMMA, has other applications in the manufacture of transparent resins, cast sheets, paints, adhesives, varnishes, coatings, the leather industry and additives.

Introduction and Application of EP Grade

EP is a grade with unique characteristics. Though it has a lower melt flow rate compared to typical SUMIPEX® PMMA grades, it has a higher spiral flow length, meaning that it is ideal for both injection and extrusion usage. To add on, this grade has stronger chemical resistance in comparison to typical SUMIPEX® PMMA grades, hence it is widely used in the automotive industry for manufacturing of rear tail lamps and for applications which requires higher chemical resistance, such as cosmetic bottles and containers.

To achieve optimal quality in moulded products, please take note of the following.

Dust Prevention

  • Handle SUMIPEX® in a clean/dust-free environment.
  • When opening bag, take special care to prevent foreign matters from entering the bag.

Contamination Prevention

  • All equipment and parts (E.g. hopper, dryer, barrel, screw, nozzle, etc.) should be thoroughly cleaned before coming into contact with SUMIPEX®.

Moisture Prevention

  • SUMIPEX® should be stored in a dry environment.

SUMIPEX® is a thermoplastic, and is flammable and soluble in organic solvents. Before using SUMIPEX®, please refer to the Safety Data Sheet (SDS) separately prepared by us.

The following information are general precautions and guidelines in the handling and storage of SUMIPEX®.

Health and Safety
During the operations of drying and processing of SUMIPEX®, local exhaust ventilation and personal protective equipment (eye goggle, gloves, respirator etc.) are necessary.

  • SUMIPEX® releases gases due to drying, melting and thermal decomposition. Avoid inhaling and contact with eyes and skin.
  • Do not touch hot resin directly.
  • If feeling unwell due to inhalation, rest in a well-ventilated place and if necessary, consult a doctor.

Flammability
Do not use/place SUMIPEX® near flames and other sources of ignition.

  • SUMIPEX® is flammable. Should it catch fire, toxic gases containing Carbon Monoxide can be generated due to incomplete combustion.
  • In case of fire, use water, carbon dioxide or foam/powder extinguishing media to put out the fire.

Disposal
For disposal of SUMIPEX®, engage an authorised contractor or consult the relevant local government agencies. Disposal should be conducted in accordance with state and local regulations.

Storage

  • SUMIPEX® should be stored in accordance with state and local regulations.
  • In case of spillage, remove pellets immediately to prevent potential slipping hazard.
  • SUMIPEX® should be kept away from direct sunlight, water and moisture and bestored at ambient temperature.

All technical information and data in this brochure are believed to be accurate and reliable. However, we do not guarantee results, freedom from patent infringement, or suitability of our products for any resultant application.

 

* This information is prepared based on the materials, information and data currently available to us. Revisions will be made when new knowledge or information is obtained.
* All data presented on our diagrams, tables and charts are typical laboratory values and are intended to serve as guides only.

We have now entered an era in which greater importance is being placed on environmental issues. In addition to its benign physical properties as a methacrylate resin, SUMIPEX® contributes to conservation of resources through its prolonged and incomparable weather resistance, serving its many applications for long periods of time. Moreover, SUMIPEX® at high yields can be reduced to its monomer form through thermal decomposition, then chemically recycled and utilised as a raw material for new resin production. Furthermore, no particularly harmful gases, such as dioxins, are produced when waste resins are incinerated, as the resins do not contain halogens. Under normal combustion conditions, SUMIPEX® breaks down completely into water and carbon dioxide; adding only minimum burden on the environment. People have been using methacrylate resins ever since the beginning of their commercial production in the 1940s. This versatile plastic is still being used in myriad applications, even into the 21st century – the century of the environment – due to its outstanding characteristics.

Homeware

SUMIPEX® PMMA is used in a variety of applications. It largely finds its use in various homeware applications including furniture and kitchen accessory products. The aesthetic advantage and scratch resistant properties favour SUMIPEX® PMMA’s extensive usage.

SUMIPEX® PMMA allows for customisation through various shapes, sizes, and colours. Furniture made from SUMIPEX® PMMA has the dual advantage of durability and aesthetic design. The inherent UV-stability combined with dimensional stability allows such furniture to be weather resistant.

Naturally, SUMIPEX® PMMA finds itself very useful in various applications where lasting and aesthetic appearances are important, including laminates and shower screens. Small items like photo frames, storage racks, tablemats, bowls, servers, chesspieces etc. are all extra-durable when made of SUMIPEX® PMMA.

Automotive

Various chemical and thermal processes can provide a myriad of structural and functional properties to SUMIPEX® PMMA. With these newly acquired properties, the SUMIPEX® PMMA resin is used as an integral part of various automotive applications.

The surface hardness and scratch resistance properties lead to SUMIPEX® PMMA being used for various appliance parts and control panel as well.

Cosmetic Packaging

SUMIPEX® PMMA is lightweight, stable, and fully recyclable and finds its use in cosmetic packaging. It doesn’t contain toxic materials like heavy metals that are harmful and hazardous to the environment, making recycling an easy and convenient process.

The cosmetic industry has been using SUMIPEX® PMMA in the form of injection moulding to create durable and creative packaging for their products. Whether it is coloured, opaque, translucent, or an elaborate design, SUMIPEX® PMMA can be customized to fit any requirement. We have taken it further to create a high chemical resistant grade, SUMIPEX® EP grade to cater to this industry.

Lighting

Modern day lighting has taken leaps and bounds from where the field stood just a few years ago. Elegant, chic, and energy-efficient lighting products for display are the new norm and SUMIPEX® PMMA effortlessly allows for producing aesthetic lighting equipment.

Superior light transmitting qualities, transparency and heat resistance are some reasons behind SUMIPEX® PMMA being extremely popular and sought after for optical applications.

The brilliance and transparent texture of SUMIPEX® PMMA result in it being predominantly used for lighting purposes. A myriad choice of colours and textures to choose from, SUMIPEX® offers a kaleidoscopic plethora of hues and effects. The result – a well-lit, aesthetically pleasing home or office space.

SUMIPEX® PMMA is also extensively used in the manufacturing of LED light guide panels and lens caps as it helps to maximise their light emitting potential. Modern homes today are embellished by various lighting fixtures as well as by skylights. Lower energy costs, aesthetic appearance and reduced environmental impact result in SUMIPEX® PMMA being preferred for lighting purposes.

Optical Lenses

SUMIPEX® PMMA is well known for its transparency and clarity. It is widely used in optical lenses industry such as sunglasses lenses and reading glasses. UV stability and ease of colourability make it a prime choice for this usage.

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.
