Lining seals out air, maintains air pressure and provides the necessary elasticity
Natural rubber: this type of rubber bladder is compact, has good adhesion, is of a single composition, is environmentally friendly and has a very stable product structure.
Reclaimed rubber: This bladder is made from various kinds of waste rubber mixed with various impurities and metal grinding. Its structure is loose and its environmental protection is not as good as natural rubber.
Butyl bladder has very good air tightness, the higher the butyl content, the better the air tightness. However, if the butyl content exceeds a certain limit, the elasticity will be affected. In general, rubber liners have a gas retention period of about 2 weeks, while butyl liners can have a gas retention period of more than 5 weeks (based on a 15% drop in air pressure).
To summarize
Butyl bladder are a better choice if you need a higher gas tightness, while natural rubber bladder are more suitable if you are more concerned about environmental protection and durability. If you are looking for a cheaper price, you can choose recycled rubber bladder.
