Materials Science Behind Next-Generation Urethane Golf Balls
Core Tech
Graduated Core Design
Traditional premium golf balls often rely on multiple layers or dual-core constructions to adjust compression, feel, and energy transfer. However, every additional layer requires another molding and alignment process, increasing the risk of eccentricity, off-center balance, and inconsistent performance.
Multi-Layer Performance Without Multi-Layer Risk
Instead of stacking separate core layers, we engineer a gradual hardness transition from the center of the core outward (soft center → firm perimeter).
This creates a stable energy-transfer structure that delivers the performance effect of a multi-layer design while reducing the risk of off-center construction.
Key Benefits
- More consistent ball performance
- Improved energy transfer
- Reduced risk of eccentricity
- Straighter and more stable flight
- Better production consistency
- Flexible compression design for different product models
Also Known As
- Progressive Core
- Dual-Stage Gradient Core
- Graduated Core Design
Cover Tech
Premium Urethane (TPU) Cover Technology
Tour-Level Control with Advanced Durability
Many traditional 2-piece golf balls use a surlyn cover because it is durable and distance-oriented. However, surlyn-covered balls often lack the soft feel and greenside control that better players expect.
Kerichem upgrades this construction with a Premium TPU / Urethane Cover, designed to provide softer feel, longer club-face contact, and improved greenside spin control.
Why TPU / Urethane Matters
For businesses, the cover material is not just a selling point. It directly affects product positioning. A TPU / Urethane cover can help a brand move from a basic distance-ball category toward a more premium performance category.
Key Benefits
- Softer impact feel
- Better greenside control
- Premium product positioning
- Improved spin performance
- Stronger differentiation from standard Surlyn-covered balls
- Suitable for premium OEM / ODM golf ball programs
Advanced Formula Coating
Performance, Protection, and Premium Appearance
Beyond the core and cover, Kerichem applies advanced coating technology to improve both performance and visual quality.
The coating system is designed for:
- Wind resistance
- Dirt resistance
- Luxury appearance
- Easy visibility
- Brand differentiation
For branding, this matters because the golf ball is not only a performance product. It is also a branded product. A premium coating helps sellers create a stronger first impression and a more professional product line.
Product Application
Solving a Long-Standing Technical Challenge
2-Piece Urethane Breakthrough
A 2-piece urethane golf ball has historically been difficult to produce successfully. The challenge is balancing soft feel, distance, durability, and core stability in a simplified construction.
Common issues include:
- Loss of distance
- Core durability problems
- Hard impact feel
- Inconsistent performance
Kerichem’s solution combines Graduated Core Technology with a Premium TPU / Urethane Cover, creating a 2-piece urethane ball that delivers soft feel, strong distance, improved durability, and greenside control.
B2B Advantage
For brands and sellers, this creates a new product opportunity:
A simpler 2-piece construction with premium urethane performance positioning.
This is especially useful for companies that want to offer a differentiated ball between standard Surlyn distance balls and higher-priced multi-layer tour balls.
3-Piece Urethane Tour
Built for premium tour-level performance with durable urethane cover, mantle layer, graduated core design, and advanced coating.
