एक ब्यूटाइल सामग्री या प्राकृतिक रबर सामग्री।

Generally, natural rubber and butyl rubber are common. Butyl rubber has better high temperature resistance and anti-aging than natural rubber and has a long service life. At the same time, the air tightness is much better, so the medium and high-grade inner tubes basically use butyl rubber as the material. Generally, natural rubber inner tubes cost a few yuan in the car repair booth. At present, butyl rubber inner tubes are sold to cyclists.
