One caveat: Typical TPE shrinkage is around 2% while that of substrate materials is closer to 1%. When looking to incorporate sustainable content into your TPE, the raw material cost may be more expensive than traditional materials for three reasons 1) supply chain maturity, 2) high demand, low supply, 3) location of source and supplier.

1.

Three common ways this can be done are 1) in a way that creates a woven structure, 2) by placing the fiber fabric into a mold that is injected with resin, or 3) by pultrusion, where the fibers are pulled through resin and then shaped and cured in a heated die.

Due to this unique viscosity/shear rate dependency, normal melt index testing (done at shear rates as low as 50 1/sec) will not reflect how the TPE will process at higher shear rates. Shear rates during extrusion processing are usually in the hundreds of reciprocal seconds and shear rates during injection molding may go as high as 11,000 1/sec.

We also offer a wide range of UL 94-recognized color concentrates for different polymer grades, from standard to engineering polymers, that fulfill the vertical burning (V-0; V-1; V-2) and horizontal burning (HB) tests.

Table 1 illustrates some common GLS Materials, their supplied hardness, and the relationship between hardness and thickness.

To convert cubic inches to cubic centimeters, the conversion factor is 16.4 (in^3 x 16.4 = cm ^3 and 2.54 in = 1 cm).
