Masha ni gaw asak kaba wa na rai nna, rubber gaw asak kaba wa na rai nna, rubber gaw asak kaba wa na rai nna, rubber gaw aten galu lang ngut ai hpang, nkau mi gaw n-gun ja ai hte n-gun ja wa nna, nkau mi gaw n-gun ja wa nna, n-gun ja wa nna, rubber a npawt nhpang elasticity hte n-gun atsam hpe mau hpa hku nna jahkrat kau ya ai, n-gun n-gun, n-gun rawng ai, garan ginhka ai, n-gun n-gun ni mung, shinggan lam amyu myu a npu e, shinggan lam ni a npu e, shinggan lam ni a npu e, galai shai wa ai a mahtai rai nga ai. law malawng gaw, katsi ai hte oxygen a n-gun yawm ai lam rai nga ai.
Oxidation gaw rubber asak kaba wa na matu ahkyak ai lam langai mi rai nga ai. Oxygen gaw, rubber molecule ni hte rubber molecule ni hte free radical chain reaction hpe hkrum sha nga ai, molecular chain gaw hkrat sum mat ai (sh) grai lai mat wa ai majaw, rubber atsam ni galai shai wa ai. Ozone gaw oxygen hta grau nna chemical hku nna shamu shamawt nga ai rai nna, rubber.} hpe grau nna hkra machyi shangun ai.
