The discussion centers on the differences between Griv-Ex and G10 materials, both of which are fiberglass reinforced plastics used primarily for knife handles. Griv-Ex is often perceived as a trendy alternative to G10, which is known for its durability and resistance to aging, particularly under UV exposure. Participants noted that while both materials exhibit similar rigidity and toughness, G10 is more resistant to environmental degradation. The conversation highlights the importance of understanding the specific polymer compositions and potential marketing implications behind these materials.
PREREQUISITESThis discussion is beneficial for materials engineers, product designers, and knife manufacturers looking to understand the performance characteristics of Griv-Ex and G10 materials in product applications.
That's why I come and ask, sounds like the rigidness and toughness are close. What I cannot find is the difference when they age. G10 sounds to be quite immune to aging even under sunlight. Hows Griv-Ex. That I cannot find.Baluncore said:Google gives many hits that compare Griv-Ex with G10 for knife handles.
They are both fiberglass reinforced plastic, so the difference will be in the polymer employed.
With any polymer, UV will be a problem in a dry or hot environment. The polymer will absorb some water that will be protective, while the glass fibre will absorb water that will be destructive.yungman said:That's why I come and ask, sounds like the rigidness and toughness are close.

Ultimate question is how long can Griv-Ex last compare to G10.
So they just very similar?Baluncore said:With any polymer, UV will be a problem in a dry or hot environment. The polymer will absorb some water that will be protective, while the glass fibre will absorb water that will be destructive.
UV will not affect the glass fibre, but will damage the polymer, especially in a dry environment.
To reduce the rate of physical and chemical reaction, keep it cool and temperature stable.
We should not all have to duplicate your research for you. You are in a position to identify the polymer employed in Griv-Ex, as opposed to the G10 you use. Is it simply a marketing term, or is it really a different class of epoxy crosslinking. Could it be that there is a protective mineral filler added to Griv-Ex ?
The lack of comparative information suggests you use Griv-Ex because it is trendy, and so increases your marketing price point.
That may be the case, it could be all in the marketing.yungman said:So they just very similar?

They actually advertise G10 is more expensive, they have two different models almost the same, major difference is the cheap one uses Griv-Ex, the more expensive one use G10.Baluncore said:That may be the case, it could be all in the marketing.
You should look for patent numbers and MSDS documentation.
