We supply most base or topsheet plastics from the Austrian Isosport. Isosport has best quality products in the world. Another manufacturer of ptex or topsheet plastics might be CPS or Socrep.

Storage: Room temperature with low temperature fluctuations. Humidity should not be too high. You can store it on the roll.

Handling only with gloves!

When you receive the plastics, make sure you brush them off with a clean cloth and if you have 93% denutered alcohol or 100% alcohol. All plastics are treated minimum on one side from factory and ready to be used with epoxy. Make sure you know how to turn it correctly.

In case you press at room temperature, make sure you wait 5-7 days before starting to cut your product. Also if possible, higher the temperature as much as possible, this will improve bounding.

IMPORTANT: Base or Ptex is flamed and sanded for successful adhesion to epoxy. Make sure you know how to turn your base properly. If not, please contact us for help!


TPU Topshet stands for Thermoplastic polyurethane. It has good transparency, good resistance to scratches, good durability and it binds well to epoxy. Not suitable for sublimation. Graphics might be printed digitally. This should work with solvent inks. The butadien in the ABS reacts with the solvent and achieves good bonding. If pretreated e.g. a thin layer of resin that might make the other types of ink stick. TPU is a softer and more easy to work on topsheet.

PBT polyester sublimation topsheet, It is white. It is suitable for sublimation. Good strength and resistance, good binding to epoxy as it also has a mesh on the epoxy side to improve adhesion.

PA, Polyamide and nylon topsheet: It is the most expensive and highest quality topsheet. Ultra durable. It is clear and suitable for sublimation. The Polyamide is usually sanded and flamed and corona treated for improved adhesion. PA is a tough and more hard to work on .

Ptex IS6000, in 0.4mm thickness is also good alternative to topsheet. It is with good durability, and easy to work with. It is about 70% clear. It is sanded and flamed.It is suitable for sublimation and printing with primer.

IMPORTANT: Please make sure you know how to turn the topsheet, which side is up/down! Check also for protective film! If in doubt contact us!
2115 TPU/ABS: The glossy smooth reflective side is the epoxy side usually. Can be tricky. Check for protective film which is the outside side.
4160 PBT: The treated and rough side with fleece is the epoxy side.
8210 PA: If sanded, the sanded rough side is the cepoxy side. If not sanded then as for 2115 TPU/ABS, the smooth side will usually be epoxy side. It can be tricky. Always think about what finish you have on the outside surface and try to locate it. The other one should be epoxy side.

Bases are divided in Extruded and Sintered. Extruded are cheaper and produced by melting. They are softer, slower, easier to repair, hold better wax. Sintered are more expensive and produced by pounding in shape. They are durable, faster, harder to repair. They can be added carbon/graphite to benefit quality. The quality number starts with 1000 and up. Extruded can be 1600, 4800 etc. Sintered can be 7200, 7500 etc. The higher the number the better the quality usually. Price reflects the quality.

You can find bases for ski/snowboard but also for kite and wakeboards.

In case you press at room temperature, make sure you wait 5-7 days before starting to cut your product. Also if possible, higher the temperature as much as possible, this will improve bounding.


Not all base and ptex is created equal. Extruded bases are softer and cheaper, more easy to repair. A 1600 base is cheapest base, very soft, while a 4800 base while still extruded offere much higher quality and durability.


Make sure to read:

If you recognize some wraping you can also try to wind it in other direction for storage.

UHMW PE is Ultra High Molecular Weight plastic. It might also called Ptex by some manufacturers. It is very strong and durable plastic, comparable to Sintered base!

Sintered bases come in numbers of IS7200 and up, indicating the density. They are very durable and hard to damage.



These are Graphite or carbon bases or race bases made with special nano additives and carbon additives to improve the gliding performance.

This should be compatible with inks that are based on solvents. Because of the interaction between the butadien in the ABS and the solvent, good bonding between the two materials is achieved. Depending on how the ink is created (for example, with a thin layer of resin), it may assist the other types of ink cling better to the paper. TPU is a topsheet material that is softer and simpler to deal with than other materials. The topsheet is constructed entirely of PBT polyester sublimation and is fully white in color. It is suitable for use in sublimation processes. Because to the addition of a mesh on the epoxy side to help in adhesion, this product has exceptional strength and resilience, as well as outstanding adherence to epoxy.
