Memory Foam hpe hpaw tsun dan ai

Memory foam gaw polyurethane hte kaga polymer arai ni hte galaw da ai bungli galaw ai foam langai rai nna, nbung katsi ai hpe hkam sha lu ai hte n-gun n rawng ai hku bai nhtang wa lu ai atsam nga ai. Ndai arung arai hpe NASA kaw nna 1960 ning daram hta lamu ga sanghpaw li dung shara ni hta shock absorption galaw na matu shawng nnan galaw shapraw ai rai nna, hpang de tsi hpaji hte nta arung arai ni hta mung jat wa ai rai nna, mattress hte pillow zawn re ai arung arai ni hta grai lang wa ai. Hkyen lajang ai lam hta, polyurethane raw materials hte chemical additives ni hpe lang nna, n-gun kaba ai -n-gun hte n-gun kaba ai foaming galaw ai lam lawm nna, n-gun n-gun hpe bra ayai shangun ai hte hkum hkrang hpe n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun n-gun (porous structure) hku nna n-gun n-gun n-gun n-gun hpe lu la ai.

Memory sponge a flat surface hpe lata hte dip dat jang, lata masat langai mi pru wa nna, loi loi hte n nga mat wa na re. Ndai gaw, myit dum ai sponge - "slow rebound" a iconic effect rai nna, kaga arai ni a matu shi a slow rebound hpe kasi la na matu yak ai.

Memory foam material gaw nbung katsi ai hte maren shi a n-gun hte n-gun hpe galai shai ya lu ai. Katsi ai hte maren loi loi hte n-gun yawm wa na re. Shinggyim hkum hkrang gaw memory foam hte matut mahkai wa ai shaloi, shinggyim hkum hkrang a katsi ai hpe hkam sha nna, n-gun n rawng wa nna, shinggyim hkum hkrang a n-gun hpe maren mara hkam la lu na re. Dai majaw, memory foam material hte galaw da ai yupku hte yupku ni gaw shinggyim hkum hkrang hte grai hkrak ai.
