Selar® PA 3426
聚酰胺 6I/6T 共聚物
DuPont Packaging & Industrial Polymers
產(chǎn)品說明：
Selar®
PA 3426 is an amorphous nylon (polyamide) resin which exhibits superior
transparency, good barrier properties to gases, water, solvents and essential
oils and high temperature structural properties which make it suitable for
consideration in a number of applications.
Features:
· Selar® PA 3426 barrier resin can be utilized in both flexible and rigid packaging structures and is characterized by very good gas O2, CO2 and moisture barrier. Furthermore, Selar® PA is unique in that its gas barrier improves with increasing relative humidity. It has excellent physical properties, high temperature resistance and excellent optical properties desirable in a structural resin. Like other nylons, Selar® PA barrier resin is an excellent barrier for many types of solvent systems. In general it has good resistance to aliphatic, aromatic hydrocarbons, dilute alkalis, higher molecular weight alcohols, and low concentrations of lower molecular weight alcohols. It is not recommended for acids or concentrated lower molecular weight alcohols. End use testing is recommended for each application. With its high degree of stiffness, very good gas and moisture barrier, solvent resistance and excellent gloss and clarity, Selar® PA used in monolayer provides a "glass like" container for rigid packaging.
Applications:
· High melt viscosity for extrusion processes such as EBM.
· Improved perbance in shrink applications when blended with nylon 6.
· Monolayer - blow molded tubes, pharmacuetical vials or bottles, typically less than 4 ounces.
· Nylon 6 modification for higher heat resistance, better oxygen barrier, broader thermobing b.
