Black Aflas or Kalrez Rings Resistant to Strong Acid and Alkali
FFKM 75 shore A O Ring
Introduction for O Rings
1.The O-ring is an annular seal having an O-shaped cross section,
the size of which
is determined by the inner diameter ID and the wire diameter CS.
2.O-ring size calculation: outer diameter = inner diameter + 2 x
wire diameter
(OD = ID + 2x CS).
3.The purpose of using O-ring seals is to prevent leakage and loss
of liquids or gases.
4.O-rings are the most commonly used type of seal because of their
simplicity, convenience,
and small installation space. As long as the groove design and
material selection are correct,
and the operating conditions are within the temperature range of
the rubber material, the seal
can have a long-term sealing effect in the static or dynamic seal.
Following elastomers can be use in O ring :
* Aflas® or Kalrez®(FFKM)
* Acrylate Rubber(ACM)
* Butyl Rubber(IIR)
* Ethylene-propylene (EPR, EPDM)
* Ethylene Acrylate Rubber(AEM)
* Fluorocarbon (FKM/FPM/FKM)
* Fluorosilicone(FVMQ)
* Hydrogenated Nitrile (HNBR)
* Neoprene Rubber(CR)
* Nitrile Rubber (Buna-N/NBR)
* Natural Rubber(NR)
* Polyurethane(PU)
* Silicone Rubber
* Styrene-butadiene Rubber (SBR)

Quality control
Material Inspection:Storage of all raw materials before the test, and issue a report on
the corresponding
material properties, compared with raw material's own property
report, two reports property values
is consistent, can put in storage.
Model Inspection:After the mold development or mold cleaning finished on the
machine, we will test
all the specifications of the mold to ensure that each cavity of
the product specifications and quality.
Production Inspection:The production process of the product inspection personnel timing
semi-finished
product inspection, ensure the quality of the rationality of
technology, defective rate control in a reasonable
range.
Quanlity Control:The quality inspection department will conduct a sampling
inspection of each batch of
products
Production Full Inspection:The optical inspection machine can ensure the appearance and
dimension
of the product are 100% qualified.
