| Material Types and General Properties | |||||
| <Table 1>Material types and general properties | |||||
| Item Type | Temp.R ange("C) | Property | |||
| High Temp.R | Low Temp.R | ||||
| ACM | 150 | -10 | It is used in diaphragm,hose for automotive application.Good
resistance to heat,ozone and oil.Generally attacked by water,alcohol,glycol and aromatic hydrocarbons.The molecular structure contains ethyl acrylate(EA),butyl acrylate (BA),and ethyl acrylate(MEA).High BA content get better low temperature resistance,and high MEA content get more oil resistance. | ||
| NR | 70 | -40 | Excellent compression set,high tensile
strength,resilience,abrasion,tear resistance,good friction characteristics,excellent bonding capabilities to metal substrate,and good vibration dampening characteristics | ||
| VMQ | 225 | 55 | The most widely temperature ranges for application.Good weather and
ozone resistance,but poor mechanical property and chemical resistance. | ||
| PTFE | 250 | -150 | Due to the low friction coefficient,it is used in oil seal
lip.However,it is poor elastic property | ||
| TPU | 100 | -40 | Polyurethane is one of the groups of elastic thermoplastic
materials.PU has been used in seal technology for many years because of their physica characteristics.It is an organic material of high molecular weight whose chemical composition is characterized by a large number of urethane groups.In addition it is characterized by extremely good mechanical properties such as high tensile strength,abrasive resistance,tear strength,and extrusion strength.However t is not resistant to polar solvents,chlorinated hydrocarbons,aromatics,brake fluids,acids,and alkalis | ||
| FKM | Excellent chemical resistance except ester and ketone | ||||
| 200 | -25 | Dipolymer | Copolymer of vinylidiene fluoride and hexafluoro propylene,and fluorine content is 66%. | ||
| -20 | Tripolymer | Copolymer of vinylidiene fluonide,hexafluoro propylene and
tetrafluro ethylene.Fluorine content is 68%.Tripolymer has better fluid resistance than dipolymer | |||
| XNBR | 100 | -40 | Modification of traditional NBR with the insertion of carboxyl
groups It has better tensile strength,modulus,abrasion than NBR | ||
3,Application scenarios
Light and medium load hydraulic reciprocated sealing system. Widely
used at industries such as mobile machinery, light machine,
agricultural machinery, injection moulding machinery, forklifts,
cranes, automobiles, forestry machinery and mining machinery, etc.
Favorable mechanical characteristics even under tough working
conditions.
4,product features
- high wear resistance, low pressure deformation and excellent
anti-extrusion performance - tear resistance especially in bending
and tensile - easy installation
