Engineered for strength-to-weight excellence, these 10-pack sheets deliver durability and precision for professional-grade scratch builds.

## Description

Depron is a brand name for Extruded Polystyrene (XPS) closed cell foam in sheet form. It is a fantastic medium for building model aircraft, and also a popular medium for architectural model building, as well as model boats and prototype design, XPS foam is stronger than traditional EPS Thermocol and can be further strengthened with carbon fiber or wood strips. Strength to weight ratio and rigidity is perfect for RC airplanesEasy to cut with precision by knifeEasily sandableSheets are flat and have a smooth finish.Technical Specifications: Size: 30inch x 20inchThickness: 5MM (thickness of sheet will be 5mm - 6mm ) Density: 300GSM 60kg/m3Quantity: 10 sheets per packWeight: 106g (of one sheet)

Review: Worth the purchase. - Used it for making an rc airplane of 5ft length and width, these sheets are exactly what you need to make it, since it's 5mm little tough to bend without breaking it, but it's doable. Wasted nothing out if these sheets. The structure are rigid to make a perfect flight.
Review: Good for planes that dont require bending the foam too much imo - Well as the title reads, its good for builds that dont require bending too much. Builds such as a piper cub or a cessna would work just fine! Also Id suggest using this depron for making scratch builds and not flitetest planes (you can, its just a bit difficult since FT planes rely on folds), but overall, I'd rate it 4 stars (mostly cuz I can't get my head wrapped around how to actually use depron properly. I'm more of a fliteboard guy). Quite durable if you ask me. All in all, a great product for scratch builds. I've got 2 scratch builds made out of this depron and I've got over 6 sheets left. So i might build a few more parkflyers.

## Questions & Answers

**Q: What if it breaks into shipping ?**
A: Well should not with all the packaging. But if it does, will send you a free replacement.

**Q: Should i go with 3mm or 5mm if the diameter of body is 13.1cm, will 5mm arc bend and sustain the tension?**
A: 3MM. 
You will not be able to bend 5MM to that diameter without breaking it. With 3MM it will be possible, however go slowly and take your time.

**Q: These sheet to kerala shipping?**
A: The sheets ship all over India. To locations covered by Amazon EasySHip, they are sent through the Amazon courier. Else to rest of India by IndiaPost Parcel service.

**Q: Can this sheet be used for fibreglass / carbon fibre moulding? (Trying to make custom vehicle body parts)**
A: Nope
