杜邦尼龙PA3426耐高温尼龙

杜邦 pa3426---pa 3426 is an amorphous nylon (polyamide) resinwhich exhibits superior transparency, good barrier properties togases, water, solvents and essential oils and high temperaturestructural properties which make it suitable for consideration in anumber of applications.

features:

selar® pa 3426 barrier resin can be utilized in both flexibleand rigid packaging structures and is characterized by very goodgas o2, co2 and moisture barrier. furthermore, selar® pa is uniquein that its gas barrier improves with increasing relative humidity.it has excellent physical properties, high temperature resistanceand excellent optical properties desirable in a structural resin.like other nylons, selar® pa barrier resin is an excellent barrierfor many types of solvent systems. in general it has goodresistance to aliphatic, aromatic hydrocarbons, dilute alkalis,higher molecular weight alcohols, and low concentrations of lowermolecular weight alcohols. it is not recommended for acids orconcentrated lower molecular weight alcohols. end use testing isrecommended for each application. with its high degree ofstiffness, very good gas and moisture barrier, solvent resistanceand excellent gloss and clarity, selar® pa used in monolayerprovides a "glass like" container for rigid packaging.

applications:

high melt viscosity for extrusion processes such as ebm.

improved performance in shrink applications when blended withnylon 6.

monolayer - blow molded tubes, pharmacuetical vials or bottles,typically less than 4 ounces.

nylon 6 modification for higher heat resistance, better oxygenbarrier, broader thermoforming window.
