Melemo ea Bohlokoa

01

Ntlafatsa elasticity ea thepa ea foam ea EVA

Ha e bapisoa le phofo ea talcum kapa anti-abrasion agent, Si-TPV e na le elasticity e molemo.
02

Ntlafatsa ho tlala ha 'mala oa thepa ea foam ea EVA

Lihlopha tse ling ho Si-TPV li ka sebelisana le li-chromophore tsa dae, tsa ntlafatsa ho tlala mebala.
03

Fokotsa shrinkage ea mocheso oa lisebelisoa tsa foam tsa EVA
