| The goal is to balance the surface texture and durometer values of the TPE to get the intended product feel. |
| Hard-Line tees feature a barb designed for use with harder durometer tubing such as polyethylene 55 Shore D and polypropropylene 80 durometer. |
| The only drawbacks of this durometer level are that turn response is a bit lower, and alternative finning such as a frog kick does not respond as well. |
| It is said to be particularly effective for dispersion in low durometer compounds and provides translucent cross-sections in unpigmented silicone rubber. |
| It is offered in 64A durometer and is well suited for outdoor use. |
| At high durometer, DIN test results were identical for the polyethers MPE-A nd MPE-C, while the polyester MPE-B had much poorer abrasion resistance. |
