What does the abbreviation NBR, EPDM, PTFE mean?

Every specialist who has ever dealt with industrial or hydraulic hoses has come across intricate abbreviations like EPDM, NR, SBR in technical sheets of various hose products. Naturally, each time the question arose, what is it, and how is it deciphered. To avoid lengthy searches on the Internet, we publish a table on our website with a breakdown of the most common abbreviations. In this table you will also find the properties of these materials. We hope that this information will help you in your work and will allow you to easily select a product that will fully meet your requirements.

Name	Designation	Composition	General properties
Natural rubber	NR	Isoprene rubber	Excellent physical properties including abrasion resistance. Not oil resistant.
SBR	SBR	Styrene butadiene rubber	Good physical properties including abrasion resistance. Not oil resistant.
Butyl rubber	IIR	Isobutylene isoprene rubber	Very good weather resistance. Low air permeability. Good physical properties. Poor oil-based fluid resistance.
EPDM	EPDM	Ethylene propylene diene terpolymer	Resistant to heat, ozone, weathering. Not oil resistant.
Cross-linked polyethylene	XLPE	Cross-linked polyethylene	Excellent resistance to most solvents, oils and chemicals. Not to be confused with the chemical properties of standard polyethylene.
High molecular weight polyethylene	UHM	High molecular weight polyethylene	Excellent resistance to most solvents, chemicals and hydrocarbons. Abrasion resistant. Suitable for food contact. Not to be confused with the chemical properties of standard polyethylene.
Teflon/Fluorocarbon resins	PTFE	Polytetrafluoroethylene	Excellent chemical resistance to solvents. Smooth, anti-adhesive surface, easy to clean.
Nitrile	NBR	Acrylonitrile butadiene rubber	Oil resistant. Good physical properties.
Neoprene	CR	Chloroprene rubber	Excellent weather resistance. Fire resistance. Good oil resistance. Good physical properties.
Polyurethane	AU	Polyester	Abrasion resistant. Not resistant to hydrolysis.
viton	FKM	Fluoroelastomer	Excellent temperature resistance. Very good resistance to chemicals.
