Rubber Material Reference, Neoprene, EPDM, Buna-N

Material Reference. The chart below is intended to help in the material selection stage of designing rubber parts / products. Rubber compounding is a very broad and technical field, since basic rubbers or elastomers are mixed with various chemicals and ingredients (and even with each other) to obtain desired physical properties.

CHEMICAL RESISTANCE GUIDE

polypropylene has better stress crack resistance and low temperature toughness than homopolymer at the expense of small reductions in other properties. Most Chemline valves and all the pipe fittings are PP-R. PP-R pipe is also available. The working temperature range of Chemline’s PP-R ball valves is –20 to 80°C (–4 to 176°F) and up to 90°C

Chemical Resistance | Hose and Fittings Source

Even within hose temperature limits, end fittings and hose size can affect performance at higher temperatures. Service Conditions: A rubber compound usually swells when exposed to a chemical. Within a given percent of swell, a hose tube may function satisfactorily if the hose is in a static condition, but may fail quickly if the hose is subject to flexing.

News - PTFE vs MPTFE (Modified PTFE)

It is a fascinating coination of the properties of PTFE and PFA (Perfluoroalkoxy), which is known for its superior mechanical properties. Like PTFE, TFM is chemically inert and has a similar range for continuous usage temperature, as well as similar resistance to water absorption. It also retains much of PTFE’s non-stick characteristics.

Most Common Types of Industrial Hoses and Their Appliions

15/2/2021· Steam hose, to an extent, runs the gamut when it comes to construction: there’s EPDM, nitrile in instances where oil resistance is needed, and chlorobutyl in more premium varieties, like when you need a hose that is going to stand the test of time. Most of these will handle temperatures north of 406°F for saturated steam and 450°F for superheated steam, with pressures up to 250 psi. on

Corrosion Protection - REMA TIP TOP

Polymer: Isoprene rubber (IR) / Styrene-butadiene rubber (SBR) Chemically resistant against: Mineral acids, bases, aqueous phases and in particular excellent resistance against moist chlorine.

Downstream Oil & Gas Solutions/Parflex

Designed to provide temperature maintenance for gases, liquids or other process materials. Has a maximum temperature rating of 250°F (121.1°C), when power to the heating cable is on, and can be steam cleaned at 400°F (204°C), when power to the heating cable is off. Electric Trace Self Regulating Low temperature (SL) and High temperature (SH)

FEP / PFA / Teftek Chemical Compatibility

PFA and Teftek® also can be used under the appellation. Though all of the fluoropolymers can be alogued in the same family, they vary in regards to thermal and mechanical properties. PTFE and PFA have a raised temperature tolerance in comparison to FEP and Teftek®. FEP, PFA and Teftek® are clear, yet PTFE is translucent.

HNBR rubber compounds - Polycomp

HNBR rubber, Properties & Appliions. HNBR is a hydrogenated version of NBR (nitrile) rubber. NBR is a copolymer of ACN and 1,3-butadiene. The NBR backbone still contains double bonds remaining from the 1,3-butadiene monomer units. These double bonds are also prone to chemical attack, thermal degradation and oxidation.
