In reply to Hotbad Peteel:
BD say this about the dropzone foam
Determining which foams absorb the highest impact forces, which foams rebound the quickest after impact and which foams offer the best weight vs. durability ratio is crucial when choosing crashpad foam. Every crashpad manufacturer claims to use high quality foam but foams are not equal—different foams with the same cell count do not absorb force the same. Through in-house testing of impact force absorption using a load cell interfaced with a Data Acquisition System, Franklin R&D has been able to record impact forces during varied, fixed-height drop tests on different foam samples, thicknesses and layering combinations. Using the data from these tests, we have blended custom-engineered foam (open- and closed-cell) using unique layering combination for optimal performance throughout our crashpad line. Our lightweight and durable combinations of foams and layers will keep you from bottoming out because, fall after fall, they do their job of dispersing impacts and rebounding quickly.
We say
Top 25mm PE40 Cross-Linked Closed Cell Foam. 25kg/m3 (approx)
Middle 75mm RX21 HLB (High Load Bearing) Open Cell Foam. 21kg/m3 (approx)
Im not sure which says most about the quality of foam used.
What information would you like?
Cheers
