Just as safe as TPE, You can say that is a senior TPE

Is S-TPE butt soft like regular TPE and/or Ultra Soft TPE or does is it more firm like Silicone?

If you look at the video on the first post, it seems even softer than TPE. But only time will tell. Cannot wait for people to start getting their hands on the material.

Appreciate the reply. Been trying to research non stop on the material. Think I'm going to pull the trigger and get me one with the material. I'll update here as soon as I get it.

WM DOLLS

Please tell me the 150M is first in line?

Will the 173H also get a LHP update? Id like to get another with S-TPE aswell

yes, you are right, the S-TPE is softer than the ultra one and also has less oil,

I'd like to some jiggle videos of some of WM's most popular dolls with the new S-TPE to see how they compare to normal TPE version.

I don´t know if this was asked yet but what about the color fade?

Would love to see the 150M and 173H get updated!

Might want to take a look at the JK 150, they're under WM. You can get it in S-TPE. I assume that's meant to be the update for the 150M. Nothing for 173H yet.

Good job wm, glad to see you improved TPE again with better softer material. Maybe I will get one stpe soon

It would be great of this new S-TPE wasn't as porous like silicone.

Styrenic thermoplastic elastomer (TPS, TPE-S) also known as Styrenic Block Copolymers (SBC) are usually described as SBS or SEBS based compounds. They are tri-blocks copolymers containing an elastomeric midblock and polystyrene endblocks. The rubber midblock is typically a polydiene (either polybutadiene or polyisoprene), resulting in the well-known families of SBS and SIS polymers. These products are the first generation of styrenic block copolymers and discovered by Shell Chemical in 1950s.

To improve thermo-oxidative and UV stability, the polybutadiene or polyisoprene rubber block of an SBS or SIS polymer can be hydrogenated to form a styrene-ethylene-butylene-styrene block copolymer (SEBS) or a styrene-ethylene-propylene-styrene block copolymer (SEPS). The double-bonds of SBS which are vulnerable to external influence are then broken. The SEBS polymers demonstrate excellent weatherability, thermal stability and high tensile strength, as well as the characteristics of a non-polar olefinic mid-block. These products are known as second generation of SBC. PHOENIX™ of Phon Tech are compounds mostly based of SEBS or SEPS polymers, some based of SBS polymers.

Quite a detailed representation of the material. The only thing that I can add to this is
