Safety surface materials
A safety surface material for a playground facility employing a monolithically mixed and troweled Thermoplastic Olefin (TPO) polypropylene/polyurethane cushion course base layer—which, for water park/spray park use is overlain by a Thermoplastic Rubber wear course top.
1. A recreational facility surfacing material comprising:
a cushion course base layer of foam polypropylene granules within an outer skin layer of non-foamed polypropylene in a mixture with Methylene Diphenyl Diisocyanate (MDI) urethane binder or Hexamethylene Diisocyanate (HDI) urethane binder; and
a wear course top layer of granulated or round Thermoplastic Rubber (TPR), Ethylene Polypropylene Diene Monomer Rubber (EPDM), or Thermoplastic Vulcanized Rubber (TPV) mixed with one of a Methylene Diphenyl Diisocyanate and Hexamethylene Diisocyanate urethane binder overlying said cushion course base layer.
2. The surfacing material of claim 1 wherein the wear course top layer comprises 20% urethane binder by weight.
3. The surfacing material of claim 1 wherein the cushion course base layer comprises 30% urethane binder by weight.
4. The surfacing material of claim 1 wherein said cushion course base layer is of a thickness of 2½″ to 4″.
5. The surfacing material of claim 1 wherein said wear course top layer is of a thickness of ⅜″ to ½″.
6. A seamless surface comprising the surfacing material of claim 1 .
7. The surfacing material of claim 1 , further comprising a synthetic turf.
8. The surfacing material of claim 1 , wherein the cushion course base layer is comprised of 1 to 3 mm granules.
9. The surfacing material of claim 1 , wherein the cushion course base layer is comprised of 1.3 mm to 1.5 mm granules.
10. A recreational facility surfacing material comprising:
a cushion course base layer of foam urethane granules within an outer skin layer of non-foamed urethane in a mixture with Methylene Diphenyl Diisocyanate (MDI) urethane binder or Hexamethylene Diisocyanate (HDI) urethane binder; and
a wear course top layer of granulated or round Thermoplastic Rubber (TPR), Ethylene Polypropylene Diene Monomer Rubber (EPDM), or Thermoplastic Vulcanized Rubber (TPV) mixed with one of a Methylene Diphenyl Diisocyanate and Hexamethylene Diisocyanate urethane binder overlying said cushion course base layer.
11. A recreational facility surfacing material comprising:
a cushion course base layer of foam thermoplastic olefin granules within an outer skin layer of non-foamed thermoplastic olefin in a mixture with Methylene Diphenyl Diisocyanate (MDI) urethane binder or Hexamethylene Diisocyanate (HDI) urethane binder; and
a wear course top layer of granulated or round Thermoplastic Rubber (TPR), Ethylene Polypropylene Diene Monomer Rubber (EPDM), or Thermoplastic Vulcanized Rubber (TPV) mixed with one of a Methylene Diphenyl Diisocyanate and Hexamethylene Diisocyanate urethane binder overlying said cushion course base layer.
12. The surfacing material of claim 11 , wherein the foam thermoplastic olefin granules within an outer skin layer of non-foamed thermoplastic olefin are foam polyethylene granules within an outer skin layer of non-foamed polyethylene.
