Liphanele tsa sandwich li fetohile ntho ea bohlokoa kahong ea sejoale-joale, tse tsejoang ka bokhoni ba tsona ba ho kopanya matla, ho thibela mocheso le ho tenyetseha. Liphanele tsena, tse nang le lera la mantlha la ho thibela mocheso le kopantsoeng lipakeng tsa mekhahlelo e 'meli ea thepa e tšoarellang, li sebelisoa haholo liindastering tse fapaneng ka lebaka la ho thibela mocheso le melemo ea tsona e metle ea sebopeho.
E 'ngoe ea thepa ea mantlha e tsebahalang haholo bakeng sa liphanele tsa sandwich ke polyurethane, e tsejoang ka ho tsamaisa mocheso o tlase, e fanang ka ho thibela mocheso o phahameng. Sena se etsa hore liphanele tsa sandwich tsa polyurethane li sebetse hantle haholo lits'ebetsong moo ho boloka matla e le ntho ea bohlokoa. Mohlala, ntlafatsong ea meaho, liphanele tsena li sebelisoa khafetsa bakeng sa marulelo le ho thibela mabota a kantle, ho thusa ho boloka mocheso o tsitsitseng ka tlung le ho fokotsa tšebeliso ea matla.
Libakeng tsa indasteri, liphanele tsa sandwich hangata li sebelisoa kahong ea lifeme, matlo a polokelo le libaka tsa polokelo ea serame. Thepa ea liphanele tsa ho thibela mocheso e thusa ho boloka tikoloho e laoloang, ebang ke ho thibela mocheso ho kena kapa ho netefatsa hore moea o batang o lula o le teng. Sena se etsa hore li be tsa bohlokoa liindastering tse kang tsa ts'ebetso ea lijo le meriana, moo taolo ea mocheso e leng ea bohlokoa.
Tšebeliso ea liphanele tsa sandwich e feta feela ho kenya mocheso. Li boetse li fana ka tšireletso e ntle ea mollo, ho kenya mocheso molumo le ho tšoarella, e leng se etsang hore li lokele mefuta e mengata ea lits'ebetso, ho kenyeletsoa mehaho ea liofisi, mabenkele a maholo, esita le matlo a bolulo. Bobebe ba liphanele tsena bo boetse bo etsa hore li be bonolo ho li sebetsana le ho li kenya, e leng se fokotsang nako ea kaho le litšenyehelo tsa basebetsi.
Jwalo ka mofani wa thepa yali-catalyst tsa polyurethane, re fana ka lihlahisoa tse kang MXC-T,MXC-C15, le MXC-37, tse etselitsoeng ka ho khetheha tlhahiso ea liphanele tsa sandwich.

Bahlahisi ba diphanele tsa sandwich ba amohelehile ho botsa ka mefuta ya rona ya di-catalyst. Ka ho sebedisa di-catalyst tsa rona tsa boleng bo hodimo, o ka ntlafatsa tshebetso ya diphanele tsa hao tsa sandwich, o netefatsa hore di fihlella maemo a hodimo a bokgoni le ho tshwarella. Bokgoni ba rona ba k'hemistri ya polyurethane bo re dumella ho fana ka ditharollo tse etseditsweng ditlhoko tse ikgethang tsa tshebetso ya hao ya tlhahiso, ho o thusa ho isa dihlahiswa tse maemong a hodimo mmarakeng.
