LF - prepolymers with excellent properties
The company is said to be an innovation leader in the development of low free (LF) isocyanate technology, which is marketed under die brand name Adiprene
LF prepolymers will therefore not be affected by the forthcoming EU-wide restrictions on diisocyanates.
It is based on polyurethane (PU) elastomers produced from Adiprene
Low Free (LF) prepolymers.
Urethane prepolymers with low free isocyanate content from the Adiprene
LF and Trixene product lines play an important role in the LANXESS product range for coatings, adhesives and sealants.
Under the brand name Adiprene
LF, unique low free isocyanate urethane prepolymers have been developed for use in adhesives, sealants, and one component foams.
The company has announced a rise in price for polyurethane prepolymers (adiprene
, vibrathane, royalcast) by 8.0%; the curatives (vibracure, duracure) by 4.0% ; and polyester polyols (fomrez) by 10.0%.
Duracast from Chemtura Corp., Middlebury, Conn., uses a specialty pure MDI and polyether, polyester, or polycaprolactone polyols.
Hawk uses a durable material called Uniroyal Adiprene
Urethane to cast his sheaths.
They settled upon Adiprene
urethane prepolymer from UniRoyal Chemical, Middlebury, CT.
The EVA midsole features an ADIPRENE
heel component rendered in a burst of lime green - a styling replicated on the Torsion System beneath.
LF prepolymers not only offer advantages in terms of health protection, industrial hygiene and safety, but compared to similar standard prepolymers, they also result in technically higher performance PU end products, according to the company.
