GLS believes these factors all play a role in the decision process and should be used in your decision process.
For example, using GLS product XL9070 (SpGr of 0.89) and GLS product G7970 (SpGr of 1.18), both 70A TPEs, the mass of the part in grams is calculated as follows:

Most GLS TPE materials replicate the mold surface fairly well.
If a matte finish is required, a rougher mold texture should be used (or a GLS product such as GLS Versalloy™ TPV Alloys, which naturally produce a matte surface).

The tub features a custom overmolded GLS Versaflex™ thermoplastic elastomer (TPE) and non-toxic PolyOne OnColor™ colorants.
In addition, Karibu chose PolyOne’s non-toxic OnColor™ colorants, which are customizable and compatible with the GLS TPE material.
Karibu selected our TPE and colorants because they are superior to conventional products,” said Michelle Hearn, director of marketing for PolyOne GLS.

TPE materials are quantified based on Shore hardness, which is a material’s resistance to indenture on a 6.3- mm minimum thickness molded plaque (ASTM D2240).
The TPE compounds developed at GLS bridge the gap of the above chemistries and offer solutions to customers with adhesion requirements for substrates ranging from Polypropylene to Polyamide which represent the opposite spectrum of polarity.
