DA-910Â is the new generation Polyphthalamide(PPA) based on functionalized fluoropolymer tailored for blown film including lamination, pipes, XLDPE.Â DA-910 needs to be added at lower level than other PPA. The average particle size 300 micron. Elliminate melt fracture in ldpe.lamination film is added to prevent gel formation. Avoids die-build up. Can be compounded with ldpe to produce master batch. Reduce die pressure and extrusion temperature. Increase output. Â Average particle size -300 micron.
