Mez factory launches new Kinetic Core™
After rumors of discontinued extruded PP core a.k.a “EPP” (the PP core most brands used for their polypro boards) most factories tried to find new cores they could use for their polypro boards to keep those boards in their range and offer a stiffer alternative than the classic PE core.
Nick “Mez” Mesritz recently announced that his Indonesian based bodyboard factory has switched all of their PP production to a new proprietary blend of EPP Expanded Polypropylene cores he has dubbed Kinetic Core. The core will be used for boards made at Mez factory (NMD, VS, Pride etc.)
Here are some more details and info abot the new core with Mez himself:
Why the switch?
When Pregis, the USA based packaging company, ceased production of Propafoam extruded PP core, the only viable option was EPP. A year or so back we contacted all the major EPP companies and began testing their foam to see who could offer the best material. We settled on Arpro® EPP from JSP, the Japanese company that pioneered the development of EPP in the 1970’s. In JSP’s own words, Arpro® is an engineered foam material, constructed by combining polypropylene resin with spe- cial additives, and applying heat, pressure and CO2 in an autoclave, where the material is formed into small plastic beads. These small, closed-cell foam beads are injected into a steam chest to create parts custom moulded into complex shapes using steam heat & pressure. The next step was to work with JSP to design our own unique, bodyboard specific, moulded cores.
What’s with the name?
Kinetic Energy can be described as “the energy of motion”, and while I am aware that true Kinetic Energy is directly related to speed and mass of an object, I liked the connotation of the word “Kinetic” and its relation to motion. We noticed during our testing phase that the Arpro® EPP had these crazy compression set characteristics, meaning that you would compress the material and it would spring straight back to shape. PE does this to some extent, but nothing like what we were seeing with Arpro® EPP. The recoil was off the charts, which can only mean one thing in body- board terms, and that is projection. Motion, projection, recoil, spring, call it what you want, but I’m calling it Kinetic.
What’s the difference between your EPP and other EPP foams?
I really can’t comment on anyone else’s foam. EPP/ BPP/ EFC, they’re all the same material, which is Expanded Polypropylene, albeit at different densities as specified by the customer. All I know is that Kinetic Core is the best EPP I have found and it gives me what I want in a PP bodyboard.
When can we expect to see it?
As they say, coming to a store near you.
