V Ring of PTFE+PPS+Carbon Material Sealing Ring with High Temperature Resistance

Product Description
The  PTFE V ring Seal is a pressure-assisted sealing device consisting of a PTFE (or other PPS+carbon+MoS2) seal partially encapsulating a corrosion-resistant metal spring energizer.
The PTFE jackets are precisely machined, filled with PTFE composites and other high performance polymers, function at temperatures ranging from cryogenic to 250 C and inert to almost all chemicals. Some types also can be used in sanitary environment.

Material
PTFE filled with PPS+carbon+MoS2

PPS is a kind of polymer with white appearance, high crystallization, hard and brittle. The relative density of pure PPS is 1.3, but it will increase after modification.
 PPS (polyphenylene sulfide) compounds offer a unique combination of properties and a cost/performance balance unmatched by other engineering thermopastics:

Application Example
Radial Seals in Static Service.
Radial Seals in Reciprocating Motion.
Radial Seals in Rotary Motion.
Inside face Seals in Static and rotary Service.
Outside face Seals in Static and rotary Service.

Application
Applications area of PPS including electronic/electrical components, precision optoelectronic components, automotive components and special industrial and mechanical components.

Size
Both imperial and metric sizes are available on all stype.
