Litharollo tsa Tekheniki tsa ho Ntlafatsa Botsitso ba Foam ea EVA
1. Ntlafatso ea Tlhahiso
1.1 Ntlafatsa Botenya ba Crosslink
Eketsa DCP ka 10–20% mme o kenye 0.1–0.2 phr TAIC ho matlafatsa sebopeho sa marang-rang le ho tsitsisa ts'ebetso ea foam ea nako e telele.
1.2 Khetha Mekhahlelo ea SEBS e Phahameng ea ho Khutlela Hantle
Sebelisa SEBS e nang le thepa e matla ea ho thibela ho fokotseha ho boloka botšepehi ba ketane ea limolek'hule. Kopanya le SEBS e thata ho feta ho ntlafatsa matla a ho tsitlella le ho hanyetsa ho tsofala.

2. Ntlafatso ea Ts'ebetso
• Eketsa mocheso oa ho folisa ka 5–10°C (mohlala, 160°C → 165–170°C).
• Eketsa nako ea ho lokisa ka metsotso e 3-5 ho netefatsa hore ho hokahanngoa ho felletseng.
• Sebelisa botsofali ba bobeli mochesong oa 80°C ka lihora tse 2 ho lokolla khatello ea ka hare le ho ntlafatsa botsitso ba ho khutlela morao nako e telele.
