PLACCEL 220N is polycaprolactone diol and its molecular weight is 2000.Polycaprolactone diols have more excellent UV resistance and heat resistance than polyether diols,and ahigher water resistance than adipate besed polyester diols.In particular,PLACCEL 220N is characterized for its narrow molecular weight distruibution.
Polyurethane elastomers made from PLACCEL 220N show excellent abrasion resistance and compression permanent set resitance.The recommended applications of these polyurethane elastomers are solid tires,rolles,scratching blades of toner for copy machines.Because of their low content of low molecule oligomer unit,the so-called"blooming"is not likely to occur.
