H 22 S
H 22 S is a high melt flow rate homopolymer with a narrow molecular weight distribution for the high speed production of low denier continuous filament for spun-bonded, nonwoven fabrics.
The major applications for spunbonded fabrics made of H 22 S are diapers, medical and sanitary tissues, protective fabrics for agricultural, industrial and medical applications, backings and linings for the furniture and carpet industries. H 22 S can also be used for the production of partially oriented yam and bulked continuous filament.
