Adiprene® L 315

ADIPRENE® L 315 is a liquid urethane polymer which can be cured to a strong, rubbery solid by reaction of its terminal isocyanate groups with polyamine or polyol compounds. When cured with MBCA l , ADIPRENE L 315 yields hard tough products that approach the strength of structural plastics in many properties. Vulcanizates of ADIPRENE L 315 effectively fill the gap between elastomers and plastics, combining high impact strength and resistance to abrasion and deformation with resilience and extensibility. These vulcanizates are resistant to the deteriorating effects of heat, water, oxygen, ozone, oils and most solvents.

ADIPRENE L 315 is a fully saturated polymer having an available isocyanate content of about 9.5% and a Brookfield viscosity of about 14 500 cP (14.5 Pa-s) at 86°F (30°C). Compounding and processing techniques used with other polymers of the ADIPRENE L family are generally applicable to ADIPRENE L 315, although allowance must be made for its high reactivity.

The vulcanizate properties of ADIPRENE L 315 suggest its use in wheels, rolls, heel lifts, bearings, metal forming tools, sporting goods, ball joint liners, and in other applications where plastics or metals are now being used.
