Epoxy Shell Nov 2004

  1. 1. Epoxy Bowling Ball Shell Introduction 2004-2005
  2. 2. Epoxy Shell
  3. 3. Normal Epoxy vs. Spaghetti <ul><li>Regular Epoxy </li></ul><ul><ul><li>Epoxy + hardener= product </li></ul></ul><ul><ul><li>Used for glue & corrosion resistant parts </li></ul></ul><ul><ul><li>Chemical resistance- repels chemicals due to tight chemical bonds </li></ul></ul><ul><ul><li>Low friction </li></ul></ul><ul><ul><li>Normally very hard (off the durometer scale) </li></ul></ul><ul><li>Modified Epoxy </li></ul><ul><ul><li>Epoxy + hardener + many secret ingredients = ball </li></ul></ul><ul><ul><li>High friction, oil absorbing bowling ball & nothing else </li></ul></ul><ul><ul><li>micro porous cell structure for fast oil absorption (1 min) </li></ul></ul><ul><ul><li>Very high friction in oil </li></ul></ul><ul><ul><li>72-75D due to mixing different epoxies </li></ul></ul><ul><ul><li>CONCLUSION- Does everything that epoxy is not suppose to do </li></ul></ul>
  4. 4. History <ul><li>Testing started in 1996 (8 years ago) </li></ul><ul><li>With reactive shell- want more hook </li></ul><ul><li>Since 2000 we have been working to get the epoxy ball further down the lane!!! </li></ul><ul><li>Modified Epoxy hooks more in oil than anything to date </li></ul><ul><li>Can hook way too early in heavy oil </li></ul><ul><li>Have built and tested over 900 balls </li></ul>
  5. 5. Modified Epoxy Shell <ul><li>Epoxy is the base material </li></ul><ul><li>Regular epoxy hooks a little more then polyester </li></ul>
  6. 6. Friction for Existing Balls
  7. 7. Epoxy Epoxy normally has about the same friction as Polyester
  8. 8. Straight Epoxy
  9. 9. Epoxy with Different Plasticizers Plasticizer A- Plasticizer C Plasticizer B- Plasticizer D – COF in oil same as White Dot on dry lane Superflex
  10. 10. Modified Epoxy Shell <ul><li>Epoxy- does not hook naturally </li></ul><ul><li>Needs “Secret” additives </li></ul><ul><ul><li>Creates maximum friction in the oil </li></ul></ul>
  11. 11. Early Epoxy Shell Test Hooked Early
  12. 12. Epoxy shell got better with time
  13. 13. Get different reactions by using different Ingredients
  14. 14. Good length- Sanded Roll vs. Polished Epoxy
  15. 15. Friction Chart for Columbia Shells
  16. 16. Today’s COF Averages
  17. 17. Epoxy Shells Can Get Ultra High Friction
  18. 18. To Get Epoxy Shell to Production <ul><li>Tested over 900 different formulas </li></ul>
  19. 19. Latest Version- Getting Close to Production
  20. 20. Spaghetti shell after 50 games - No loss in Performance
  21. 21. Where to start the first Epoxy ball? <ul><li>Big hook ball for oil? </li></ul><ul><li>Ball for typical house condition? </li></ul><ul><li>Somewhere in between? </li></ul>
  22. 22. Qualities of Epoxy Balls <ul><li>Shell has unique, marbleized appearance </li></ul><ul><li>Ball changes color as oil is absorbed </li></ul><ul><li>Unique epoxy smell </li></ul><ul><li>Can adjust performance by altering the additives </li></ul><ul><li>More midlane hook </li></ul>
  23. 23. <ul><li>(or should we say, the start) </li></ul>The End
