Conclusion First
Industry materials usually refer to MPP as microcellular polypropylene foam and EPP as expanded polypropylene. SVS Chuzhang uses an MPP core, while Jijing uses an EPP core; when choosing, also consider the 16mm thickness, approximately 225g weight, paddle shape, paddle face, and actual hitting feedback together.
What Material Names Tell You
- Both MPP and EPP are based on polypropylene
- Different foaming structures, densities, formulas, and molding processes will alter final performance
- Material abbreviations alone cannot prove power, control, spin, or durability
How SVS Uses Them
- Chuzhang: Cike and Bianhua use the same MPP paddle body
- Jijing: Chidao and Hongtianlei use the same EPP paddle body
- Paddles are all 16mm and approximately 225g
How to Compare
- First, playtest with the same type of ball, on the same court, and using the same drills.
- Compare net touches, transition zone resets, baseline drives, and continuous fast blocks
- Record results that you can consistently repeat, not just the first hit
