SGP na-anọchite anya ionic intermediate membrane (Sentryglass Plus), nke bụ ihe eji eme sanwichi dị elu nke DuPont mepụtara. A na-egosipụta arụmọrụ ya dị elu na:
;
1, ezigbo ihe eji arụ ọrụ, ike dị elu. N'okpuru otu ọkpụrụkpụ ahụ, ikike ibu nke sanwichi SGP dị okpukpu abụọ nke PVB. N'okpuru otu ibu na ọkpụrụkpụ ahụ, mgbagọ nke iko SGP laminated bụ otu ụzọ n'ụzọ anọ nke PVB.

3, nkwụsi ike siri ike, iguzogide mmiri mmiri. Ihe nkiri SGP enweghị agba ma doo anya, mgbe anyanwụ na mmiri ozuzo gasịrị, ọ na-eguzogide ụzarị kemịkalụ, ọ dịghị mfe ịcha odo, ọ na-acha odo odo < 1.5, mana ọ na-acha odo odo nke ihe nkiri sanwichi PVB bụ 6~12. Ya mere, SGP bụ ezigbo iko laminated nke nwere oke ọcha.
