I eventually found the image of the rear side of a Sueke rubber cover. Translation says:
Hangzhou Suke Sports Goods Co., Ltd.
TEL: +8613115739772
I guess the best way to understand the difference is by asking to the producer, but we may need a chinese speaker for that.
BTW on Chinese market I also see "Suke no. 1" and "Suke no. 2", I guess that's same glue as Sueke but in different bottles, this time is same color and different labels.
EDIT: from another Sueke rubber:
