Evoh (ethylene vinyl doro copolymer)
Etlelene Vinyl Doro Copolymer inzvimbo yePolymer inosanganisa maitiro eVETHLYNE Polymers uye iyo gasi rinotsungirira zvivakwa zveEndylyne Doro Polyne. Iyo inoonekera zvakanyanya uye ine gloss yakanaka. Evoh ane zvakanakisa zvipingamupinyi zvemweya uye nemafuta, aine simba rakanakisa simba, nekukasira, kupfeka kurwisa, kupesana nekutonhora, uye kuita kwemusoro, uye kuita kwakanakisa. Kuita kwekutambisa kwaEvoh kunoenderana nezvematatu ezvinyorwa. Kana iyo ethyley yezvemukati inowedzera, iyo gasi rekumanikidza kuita basa rinoderera, asi kushanda kwakashata kwekuita kunowedzera, uye zviri nyore kugadzirisa.
Zvigadzirwa zvakarongedzwa neEVOH zvinhu zvinosanganisira masosi, zvigadzirwa zveDairy, zvigadzirwa nyama, zvigadzirwa zvigadzirwa, nezvimwe.
PVDC (Polyvinylidene Chloride)
Polyvinylidene chloride chloride (PVDC) ndeye polymer ye vinylidene chloride (1,1-dichloroethyle). Iyo tembiricha yekushambadzira yeHomopolymer PVDC yakaderera pane iyo yekunyungudika, ichiita kuti zviome kunyungudika. Naizvozvo, sezvinhu zvekutakura, PVDC ndeye Copolymer yeVinylidene Chloride chloride chloride, iyo ine yakanaka Airlenness, iyo Corrostion kuramba, kudhinda kwakanaka uye kupisa kuiswa zvivakwa.

Nekuda kwekutya kushamwaridzana pakati peimwe nzvimbo yekunyepedzera uye inoshanda lesins, inodikanwa kuti uise zvimwe zvinonamatira pakati peaya maviri matema kuti aite se glue uye gadzira yakasanganiswa yeyakawirirana. Iyo yekuzvinamatira inoshandisa dendere resin, inowanzo shandiswa inosanganisira polyolefin yakabatanidzwa neye malecic andeddride uye ethylene vinyl acetate copolymer (Eva).
Maleic Anhydride akaputirwa Polyolefins
Maleic Anhydride akabatanidzwa polyolefin anogadzirwa nekugadzira maleic anydride muPolyethylene kuburikidza nekuwedzera kwekuwedzera, kuunza mapoka ePolar pamaketari asina-polar. Iyo inonamatira pakati pePolar uye isina-polar zvigadzirwa uye inowanzo shandiswa mune mafirimu emapuranga ePolwenyfins akadai sePolypropylene and nylon.
