Rubber layer that covers the outside of the fender to protect the cord layers and the inner liner rubber from
abrasion and other external forces.
2)Inner rubber layer
liner of a rubber membrane that seals the pressurized air inside the fender.(In general,we will make some inner
rubber container in advance and inflate them.few days later,we will test the pressure again.The one which it's
pressure did not change is good one.We will put it into store and when clients order we can use it directly.
This can ensure every fender we send to client is airtight one)
