Sumparwood™ is an advanced polystyrene wood made from recycled materials such as plastic fiber, leveraging a series of patented and proprietary technology.
Sumparwood™ has the appearance and touch of natural teak. Each piece is also simulated with natural wood grain details, both on the surface and within cross-sections.
The Sumparwood™ manufacturing process is carefully designed as to produce a slight and unique variation in color for each piece, thereby further resembling natural wood. In addition, the depth of the color also varies depending on lighting spectrums and viewing angles.
Sumparwood is made of a proprietary blend of Polystyrene (PS), including recyclable plastic
such as foam cups and tableware. It contain no cellulose-based fibers, which makes it a perfect material for outdoor furniture.
SUMPARWOOD™ TEST RESULTS
- Range of temperature: -16.6 to 158 Fahrenheit (Results from compressive and flexural strength testing with SGS approval)
- UV Inhibition: four years of exposure to sunlight (Xenon arc 300 W UV simulator for 448 Hours)
- Breakeven: Screwing two bolts to each end of a slat piece, breaking happens when exceeding 2000 pound of pressure.
