The most vital development work in sealing technology is done in optimising the geometry and improving the characteristics of the materials. Wall factory offers an extraordinarily wide variety of materials for large diameter seals, in order to meet any operating demands. Only the standard materials are listed in this brochure. All other material solutions will be provided by Wall factory upon request:
Polyurethane elastomer (CPU) developed by Walle, with extraordinarily high pressure resistance and abrasion resistance, hydrolysis-resistant;
Special hard grade polyurethane elastomer (CPU) developed by Walle, with extraordinarily high pressure resistance and abrasion resistance, hydrolysis-resi- stant;
NBR material for seals and pre-load elements;
H-NBR material for high thermal and chemical stress, good mechanical properties and suitable for a wider temperature range
FPM (FKM, viton) material with very high chemical and thermal resistance; outs- tanding ozone, weathering and ageing resistance; EPDM material for mineral oil-free, aqueous media or steam applications;
TFE/P (Aflas) material with high thermal and chemical resistance, even in aqueous and amine-containing hydraulic fluids and hot steam; PA6G material for guide and back-up elements
UHMW-PE material for guide and back-up elements; very good gliding properties in water; low moisture absorbtion.
PTFE-pure material for static support elements and subordinated guide parts; only partly useable for seals; practically resistant to chemical attacks. Very low coeffi- cient of friction; *
PTFE with 15% glass-fibre + 5% molybdenum disulphide (MoS2); for back-up and guide elements; for gliding components of compound seals for spring energized or O-ring activated seal profiles; *
PTFE with 40% bronze; for back-up and guide elements; for gliding components of compound seals for spring energized or O-ring activated seal profiles
Now our company is specialize in producing seals of these materials: Viton A, Viton B, Viton F, Viton GF, GLT, GFLT, ETP, Aflas, ACM, AEM, VMQ.
Besides, we also product below item, such as PTFE Rubber Diaphragm, clamp seals, P seals, H seals, Casing Tubing Hanger Packers, FS Casing & Tubing Seal, Springsele, Teesele, Valve Rod Seal, Metal End Cap Seal, and so on.
We have the highest quality and lowest costs in the industry delivered on time.
