Vacuum machine Seal Rings

Commonly used types and uses of materials produced by: sealing materials should meet the requirements of sealing function.

In order to meet different application requirements. But on the whole the sealing material shall meet the following requirements:

1) material density is good, not leaking medium;

2) have suitable mechanical strength and hardness;

3) good compressibility and elasticity, permanent deformation is small;

4) does not soften under high temperature, do not decompose, does not harden at low temperatures, do not rattle;

5) corrosion-resistant properties, acid, alkali, oil and other medium and long-term work, their small size and hardness changes without adhesion on metal surfaces;

6) small coefficient of friction, wear resistance is good;

7) has combined with sealing surface softness;

8) good aging resistance, durability;

9) easy to manufacture, cheap, based on easily.

Usually material: NR,SBR,IIR,CR,EPDM, special rubber: Viton (FKM), and VMQ. and so on.

Color: black, Brown, yellow, green, blue, white

Hardness: 40 (± 5) (± 5) (60 (± 5) (± 5) (± 5) (-5)

Standard: AS568,BS,P,V,G,BS,GB,M, non-standard

1. do not indicate otherwise specified dimensions (unit: mm)

O-ring size inside diameter (ID) * diameter (C/S);

2. in the absence of special instructions, most of the products design of mold rubber kind 70 specifications depending on their material;

3. due to the mold shrinkage coefficient of different materials with different, existing mold cannot process certain sealing rings, separate molds needed.

4. different material chemical compatibility is different, please consult before ordering, we will provide you with a detailed answer.
