Engraved; ABS vs. PBT, what's the difference?

post #1 of 6
Thread Starter 
This question is torturing me, because I want to replace keycaps but I don't want to feel like I'm missing out. They're going to be engraved, so I'm not worried about lettering fading away, but rather how long the keys will stay textured, and which one will look and feel better after 1 year or 5 years of use.

The thing is that I can get them both for the same price, but WASD's ABS keycaps are way more customizable, but I've read a bit of "PBT is just better". Basically if there is solid, noticeable differences that will appear or I will feel in the long term.

In short, enlighten me on why PBT is better, and/or convince me PBT is > customizable ABS.

  • Expensive
ABS Plastic (Acrylonitrile Butadiene Styrene)
  • Solvents will "melt" the keys
  • Keys develope "shine" faster
  • Low Cost
  • Light Weight

Quoted from the guide. I would also add that PBT has a bit more texture to it than ABS.

ABS is more smooth, PBT is more textured. I prefer PBT myself.

I also prefer PBT, both for the texture and the ant-shine buffer. I live at my pc, so ABS caps develop shine really fast for me.
