Autoclave

Open steam

R-4

Used in the case of extreme slurry abrasion where R -6 is not sufficient.

For abrasion resistance of slurry

42 ± 7

Type/Shore A

R-5

Inadequate for slurry abrasion, but applicable for abrasion with large diameter of coarse particle and high loading.

For special abrasion resistance

62 ± 7
Type/Shore A

R-6

(R-16)

Standard grade of natural soft rubber for acid resistance.

Alkali-resistance and slurry abrasion resistance shall be separately considered.

Storage and piping for chemical resistance

Suitable for caustic soda

62 ± 7

Type/Shore A

R-7

(R-17)

Inadequate for general acid and alkali resistance.

Used for surface application of single or on hard rubber.

 

Hydrofluoric acid resistance (Only a little amount in phosphoric acid)

67 ± 7
Type/Shore A

R-8

(R-18)

Soft rubber blended with hard rubber for vulcanization.

Used as SH type

(SH-8168, SH-8078, SH-78)

70 ± 7

Type/Shore A

R-8I

Compound of low Ca and Mg

Same as R-6 and R-8

42 ± 7

Type/Shore A

 

 * With regard to service condition, in the case of food-related, R-6(R-16) is certified by the Japan Ministry of Welfare No.85.
