“Let me know the thickness. If the thickness is less, then 6bar pressure might affect the bladder”. This question is from our customer, he worries if the bladder thickness is less, bladder can not load enough pressure. Generally speaking, the inflation pressure of our rubber airbag is 7.5kg. It is made of 6 layers of inner and outer cord fabrics by hand. The thickness is also calculated by technicians. So totally no need worry about the thickness.
