Title
(EN) SYNTACTIC POLYURETHANE ELASTOMER BASED ON SOFT SEGMENT PREPOLYMER AND NON-MERCURY CATALYST FOR USE IN SUBSEA PIPELINE INSULATION
(ID) ELASTOMER POLIURETAN SINTAKSIS BERBASIS PREPOLIMER SEGMEN HALUS DAN KATALIS NON-MERKURI UNTUK PENGGUNAAN DALAM PENYEKATAN PIPA-SALURAN BAWAH LAUT
Abstract
(EN)
Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a prepolymer made from a polyether polyol and a polyisocyanate, a chain extender, a polyisocyanate and microspheres. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.

(ID)
Elastomer poliuret.an sintaksis yang dibuat. menggunakan katalis non-merkuri. Elastomer yang terbuat dari campuran reaksi yang mengandung prepolimer terbuat dari polieter poliol dan poliisosianat, pemanjang rantai, poliisosianat dan mikrosfer. elastomer melekat dengan baik ke dirinya sendiri, yang membuatnya sangat berguna sebagai isolasi termal untuk jaringan pipa dan struktur lain yang memiliki geometri yang kompleks.
