REINFORCEMENT METHODS
 

Spiral
The spiral reinforcement is mainly used for the production of low pressure hoses. It has a high fatigue strength and flexibility.
Braid
Braid reinforcement is used for the production of high pressure hoses. This method gives a somewhat less fatigue strength and an increased stiffness. This implies a better form stability than with the spiral reinforcement.
        
Spiral reinforcement with steel wire helix
Spiral reinforcement with embedded steel spiral is mainly used for the production of hoses meant to withstand overpressure and vacuum. The steel spiral implies improved flexibility, that is to say, smaller bend radius.

Spiral with embedded anti-static wire
Spiral reinforcement with embedded anti-static wire is used in hoses meant to withstand overpressure, and conveying for example petrol, oil, abrasive particles, chemicals, etc. The wire is manufactured in copper and has very good characteristics of discharging static electricity.

 



RUBBER TYPES

 

Natural rubber (NR) -60 ºC +70 ºC
Natural rubber is recognizable by its elasticity and abrasion properties, as well as its endurance limit. Natural rubber has poor resistance to oil and gasoline, and a limited ozone and heat resistance. Natural rubber was the first type of rubber to be used commercially in the middle of the Nineteenth century. Today, natural rubber is used among others within applications like car tires, details in rubber, conveyer belts and hoses for material conveyance.
+ High grade of resistance to abrasion, elasticity characteristics. Good resistance to cold.
- Poor resistance to gasoline and oil. Poor heat resistance.

 

Styrene-butadiene rubber (SBR) -55 ºC +90 ºC
SBR rubber has properties that ressemble those of natural rubber with better heat and aging properties. Fracture characteristics, tear endurance and solidity are however worse. SBR is often mixed with natural rubber to optimize characteristics and price. SBR has a somewhat lower price than natural rubber. SBR is only to a certain extent resistant to oil.
+ High grade of resistance to abrasion, elasticity characterisitcs, good heat tolerance.
- Poor weather and ozone resistance.

Nitril rubber (NBR) -35 ºC +100 ºC
Its most notable quality is the resistance to oil, but even to gasoline and solubles. Resistance to oil increases with an increasing achryl nitrate level, but to the detriment of an increased stifness under cold conditions. Poor ozone and weather resistance. Nitril rubber is the most common rubber used in our hoses today. Nitril is for example the standard material used in O-rings and seals.
+ High gasoline and oil resistance, good resistance to chemicals.
- Poor weather and ozone resistance.

Chloroprene rubber (CR) -55ºC +100 ºC
CR is a synthetic rubber introduced by Du Pont in 1931 called duprene, which was later changed to neoprene. It is a chloroprene rubber material. Du Pont succeeded so well in marketing its product that neoprene has become a synonym for chloroprene. CR has good heat properties, weather resistance, abrasion properties, and is resistant to oil.
+ Good weather and ozone resistance. Good resistance to oil.
+ Good heat resistance.
- Moderate gasoline resistance.

Polyeurethane (PU) -30 ºC +80 ºC
Polyeurethane is a material that has become common within hoses lately. Polyeurethane has remarkable abrasion properties and is used in many thermoplast hoses. It is even used in rubber hoses within hydraulics as outside protection shell. Resistance to oils, gasoline as well as ozone is quite good. The downside is the limited temperature spectrum and that it is not compatible with acids.
+ High grade of resistance to abrasion, high weather and ozone resistance. Good resistance to gasoline and oil.
- Sensitivity to hydrolysis

Silicone rubber -90 ºC +250 ºC
Silicone rubber hods a unique position. Thanks to its special structure, this material has a very high heat resistance and litlle stiffning under cold conditions, and the widest temperature spectrum of all types of rubber.
+ High heat tolerance.
+ High weather and ozone resistance.
+ Good chemical resistance.
- Poor gasoline and oil resistance.
- Sensitivity to hydrolysis.

EPDM rubber (EPDM) -55 ºC +120 ºC
A relatively new material from the sixties. EPDM rubber is recognizable to its high heat and ozone resistance. It is used in cooling hoses as well as in sealing strips. Non resistant to oil.
+ High weather and ozone resistance. Good heat tolerance, good resistance to chemicals, good abrasion.
- Poor gasoline and mineral oil resistance.

Polytetrafluoro ethylene (PTFE) -80 ºC +260ºC
Fluoro plastics and PTFE in particular are incredibly resistant to all kinds of chemicals, including concentrated acids and organic solubles. Only alcaline metals, fluor and fluor compounds have a damaging effect on PTFE. Moreover, PTFE has a very wide temperature spectrum. In common language, one usually uses the denomination teflon for this material, which is the registred trademark of Du Pont for PTFE.
+ High temperature tolerance.
+ High resistance to chemicals.
+ Good weather resistance.
+ Low abrasion.
+ Good gas permeability:
+ Self-lubricating.
- High price.
- Poor elasticity
