1Deviating from ISO 37 standard test piece S2 is tested with a traverse speed of 200 mm/min.
2The adhesion quality depends on mold design, product geometry and process parameters.
All values published in this data sheet are rounded average values.
The expected shelf life of the TPE granules is a minimum of 24 months from the date of delivery, provided that the storage instructions are followed and the product is kept in the unopened original KRAIBURG TPE packaging.
Dry conditions at room temperature (below 40 °C/ 104 °F), away from heat sources and direct sunlight, must be maintained for proper storage. Contact with nitrogen oxides during storage should be avoided.
