Martial arts sparring equipment padding (ESA or PVC foam?)


I’m a student working on a design project that requires the use of a foam the same or similar to that used on martial arts sparring equipment padding. Ads for some of this equipment mention “vinyl-dipped ESA foam” and “vinyl-dipped PVC foam”. I can’t seem to find any info on these foams. Can anyone here direct me to an info source or, better yet, a supplier of this type of foam? How about the vinyl covering?

Thanks in advance for any help.

Try to find someone in your area who specializes in reconditioning automotive interiors. They could supply you with materials and/or vendor names.
