Examining new classes of PU elastomers

Polyurethane elastomer systems based on the new aliphatic diisocyanate, trans-bis(isocyanatomethyl cyclohexane) also referred to as (trans-1,4-H6XDI trans-1,4-hydrogenated xylylene diisocyanate), will be introduced.
This new aliphatic diisocyanate has a very compact, linear and symmetrical structure that results in ultra high-performance properties. In particular, the resilience and tear strength are superior or comparable to other ultra high-performance elastomers based on para-phenylene diisocyanate (PPDI) and o-tolidine diisocyanate (TODI).
Being aliphatic, isocyanate prepolymers based on trans-1,4-H6XDI have superior stability in regards to shelf life, heat history and exposure to humidity. Isocyanate prepolymers may be processed with short chain diols such as 1,4-butanediol or aromatic diamines with a wide range of pot life.
Elastomers based on trans-1,4-H6XDI have superior light stability resulting in parts that retain their color over a longer period of time than elastomers based on aromatic diisocyanates.
This technical paper will present the physical/mechanical properties, thermal mechanical behavior and abrasion resistance properties. Results will show that elastomers based on trans-1,4-H6XDI offer ultra high-performance properties.
