Makrolon® WB1239 is a polycarbonate grade formulated specifically for production of high-capacity water bottles that offers several advantages compared to glass and other materials.

The grade also complies with international standards for food contact and can be used repeatedly.

Weighing just 750 grams (1.65 lbs.), a five-gallon water bottle made out of Makrolon® WB1239 polycarbonate is 15 percent lighter than similar size glass bottles. This makes maneuvering the water bottles much easier.

Compared with other plastics, such as polyethylene terephthalate (PET), polypropylene (PP) and polyvinyl chloride (PVC), this polycarbonate grade offers a superior combination of stiffness, toughness, break resistance and temperature resistance. This helps create high-capacity bottles that have a long service life.

Key properties of bottles molded from Makrolon® WB1239 polycarbonate include:

  • Suitability for food contact applications
  • High mechanical strength and impact strength
  • High heat resistance
  • Dimensional stability

Additionally, water bottles made out of Makrolon® WB1239 polycarbonate can be cleaned and re-filled repeatedly, allowing drinking water to be efficiently distributed. A key advantage for the water-cooler sector.
