VULKOLLAN in its classic form is a polyurethane elastomer based on naphthalane 1,5-disocyanate Desmodur 15 (NDI), polyester polyol and special chain extenders. VULKOLLAN is produced by hot casting.
The raw materials used for VULKOLLAN are subject to tight specifications and strict quality controls. All licensed processors must follow COVESTRO guidelines for VULKOLLAN formulations and production processes, otherwise they cannot use the name VULKOLLAN.
VULKOLLAN wheels take up to 4 weeks to produce, due to the stabilizing requirements needed. Thus it is important to allow adequate time for any application.
