Eldon James Corp Material Quick Reference

Material Selection

Begin by checking the Chemical Resistance charts. These charts provide a general reference for establishing compatibility between our plastic materials and various chemicals. Note: the charts are for reference only – we strongly recommend testing to a standard that takes into account the actual chemical concentrations and environmental conditions specific to your application.

NATURAL MATERIALS

Antimicrobial Protected (AG)

Antimicrobial protected Ag fittings are available in Nylon, Kynar®, Polypropylene and HDPE. These fittings incorporate natural silver ion protection to guard against microbial colonization and biofilm formation on their surfaces. Kynar® Ag fittings (AGNK) are autoclavable.

Natural Kynar® (NK)

Natural Polyvinylidine Fluoride (PVDF)resin – translucent, off-white hemispheres. High stability in harsh thermal, chemical and ultraviolet environments. High toughness and mechanical strength, low permeability, abrasion r

CrystalVu™ (CVU)

CrystalVu™ (polyolefin): A clear transparent alternative to polycarbonate containing no Bisphenol-A (BPA) – will not deform at temperatures to 180 °C (356 °F). Autoclavable – enhanced characteristics compared with polycarbonate include: superior chemical resistance; no crazing with multiple autoclave cycles plus gamma and EtO Sterilization compatibility – USP Class VI, EU 2002/72/EC.

High Density Polyethylene (HDPE)

HDPE complies with FDA 21 CFR 177.1520 when used unmodified for the manufacture of food contact articles. HDPE has various applications for use in medical products and devices. It has excellent resistance to chemicals, but exhibits lower thermal resistance than other materials. It is a softer material than nylon or polypropylene and much softer than Kynar®.

Nylon - Natural (NN) / Medical (MN)

Nylons exhibit good tensile strength, moderate stiffness and high impact resistance. They’re resistant to fuels, lubricants and many chemicals, but vulnerable to attack by phenols, strong acids and oxidizing agents. MN White Medical Nylon is made from the same resin as Natural Nylon, but has an FDA compliant white colorant added.

Animal Derivative Free Polypropylene (PP)

A polypropylene formulated for biomedical and bioprocess applications. Meets FDA requirements 21 CFR 177.1520(a)(3)(i) and (c)3.1a. PP material has a Drug Master File listing. It is radiation stable and is resistant to solvents, chemicals, water and other inorganic environments. It resists most strong mineral acids and bases; however, it is subject to attack by oxidizing agents.

INDUSTRIAL & AUTOMOTIVE MATERIALS

Black Nylon (BN)

Made from 6/6 nylon – exhibits strength, moderate stiffness, high service temperature, high impact resistance and tensile strength. Resistant to fuels, lubricants and many chemicals, but vulnerable to attack by phenols, strong acids and oxidizing agents. Used in fuel line, vacuum systems and general purpose applications: automotive industry approvals.

Glass-Filled Black Nylon (GFBN)

Temperature Range -50 °F to 275 °F (135 °C) • Pressure 150 psi @ 70 °F Heat Deflection Temperature – ASTM D64: 475 °F (246 °C) @ 264 psi GFBN is a standard material used in automotive and marine under-the-hood, heater and coolant applications. GFBN’s enhanced impact resistance results from inclusion of uniformly dispersed glass fibers that add strength to the resin: automotive industry approvals.

Stainless Steel (SS)

Fittings produced with 316L alloy perform well in high temperature, harsh physical environments. 316L molybdenum bearing stainless steel has excellent impact and chemical resistance, but is less resistant than other types of stainless steel to highly oxidizing acids, such as nitric acid. The material has wide application in pharmaceutical and dairy processing and is used extensively in brewery, beverage and bioprocess industries.

White Polypropylene (WP)

Temperature Range -9 °F to 150 °F (66 °C) • Pressure 125 psi @ 70 °F
White Polypropylene has the same physical and chemical resistance properties as Natural Polypropylene, but is less expensive. WP fittings contain recycled runner material produced during virgin material, Natural Polypropylene production runs. White Polypropylene fittings are manufactured to the same tolerances and quality standards as our Natural Polypropylene fittings – WP is not a USP Class VI material and is not lot traceable.

White Nylon (WN)

Temperature Range -50 °F to 275 °F (135 °C) • Pressure 125 psi @ 70 °F
White Nylon has the same chemical and physical properties as Natural Nylon. W fittings contain recycled runner material produced during virgin material, Natural Nylon production runs. White Nylon fittings are manufactured to the same tolerances and quality standards as our Natural Nylon fittings. Lot traceability certificates are not available for White Nylon.

Gray Kynar (PVDF)

Temperature Range -80 °F to 226 °F (108 °C) • Pressure 260 psi @ 70 °F
Gray Polyvinylidine Fluoride (PVDF) fittings exhibit the same physical and chemical resistance properties as Natural Kynar®. PVDF fittings contain recycled runner material produced during virgin material, Natural Kynar® production runs. For applications that do not require lot traceability or a material that meets USP Class VI requirements, PVDF fittings represent an excellent value.
