As the pickleball market continues to evolve, paddle core technologies are also rapidly advancing.
Today’s mainstream paddle core options mainly include traditional PP honeycomb cores, upgraded Gen 4 PP structures, and newer EPP foam cores.
As a professional pickleball paddle OEM manufacturer, we are frequently asked by brands about the differences between Gen 4 PP and EPP cores.
In reality, these two core structures represent different playing characteristics and product positioning.
Many premium T700 raw carbon paddles today use upgraded PP core technologies.
What Is a Gen 4 PP Core?
Gen 4 PP (Generation 4 Polypropylene Core) is generally considered an upgraded version of the traditional PP honeycomb structure.
Compared with standard PP honeycomb cores, Gen 4 PP typically offers:
- Better structural stability
- Larger sweet spot
- More consistent power feedback
- Reduced vibration
- Improved compatibility with thermoformed construction
For OEM brands, Gen 4 PP remains one of the most balanced and market-accepted solutions in terms of performance and production stability.
What Is an EPP Core?
EPP (Expanded Polypropylene) is a highly elastic foam material.
Compared with traditional honeycomb structures, EPP focuses more on:
- Softer feel
- Higher rebound performance
- Better vibration absorption
- Quieter impact sound
- More explosive power release
In recent years, EPP core technology has gained increasing attention from professional players and premium paddle brands.
Especially for paddles seeking a balance between control and power, EPP offers unique characteristics.
What Is the Biggest Difference Between Gen 4 PP and EPP?
In simple terms:
Gen 4 PP:
More focused on stability, balance, and control.
EPP:
More focused on elasticity, power, and vibration dampening.
Different brands choose different core structures depending on their target player preferences and market positioning.
Which One Is Better for OEM Customization?
For OEM customers, we usually recommend:
Gen 4 PP if your focus is:
- Mainstream market demand
- Balanced all-around performance
- Stability and control
- Mature mass production solutions
EPP if your focus is:
- Premium product lines
- Product differentiation
- Stronger power feedback
- Innovative paddle technologies
What Core Customization Options Do We Support?
As a pickleball paddle OEM manufacturer, we support:
- Gen 4 PP Honeycomb Core
- EVA Foam Core
- EPP Foam Core
- Custom thickness options
- Thermoformed & cold-pressed constructions
- Swing weight tuning
- OEM graphics and packaging customization
We can help brands develop different paddle structures based on market positioning, player style, and performance goals.
Final Thoughts
Neither Gen 4 PP nor EPP is universally “better.”
The real key depends on:
- Brand positioning
- Playing style
- Price range
- Desired player experience
The future of pickleball paddles will not only be about materials, but also about overall structure engineering and playability optimization.
