Rubber Application

Natural Soft Rubber (NSR)

Ha Thanh exclusively applies the technology, materials, and process techniques for rubber lining from OHJI Japan, providing a full-package service from rubber materials to complete project execution.

Natural Soft Rubber (NSR) stands out for its high elasticity and good load-bearing capacity. NSR is widely used across various industries due to its flexibility and high durability.

  • Reliable applications
  • Precise thickness
  • Strong adhesion
  • Easy defect detection
  • Easy to repair
  • Very durable service life

Characteristics

  • ( 01 )

    High Elasticity

    NSR soft rubber has excellent stretch and shape recovery capabilities, making it suitable for applications requiring flexibility and minimal deformation.
  • ( 02 )

    Good Load-Bearing Capacity

    The soft rubber can withstand high tensile and compressive forces without fracturing, helping the product maintain its integrity throughout its use.
  • ( 03 )

    Abrasion Resistance

    With strong anti-abrasion properties, NSR ensures a long service life for products, even under harsh operating conditions.
  • ( 04 )

    Vibration Damping Capability

    NSR rubber effectively absorbs vibrations and reduces noise, protecting machinery and creating a more pleasant working environment.

Application

Ha Thanh exclusively applies the technology, materials, and process techniques for rubber lining from OHJI Japan, providing a full-package service from rubber materials to complete project execution.

Rubber mats with a thickness from 3mm to 20mm (1m width) and unlimited length, 100% free of air bubbles. Widely used for anti-corrosion lining for the equipment operating in the conditions below.
Resistant to acids, alkalis, and abrasion.

OHJI Rubber Characteristics Applications Vulcanization conditions Hardness
(Type A)
Autoclave Open steam
OHJI R-4
  • Used in the case of extreme slurry abrasion where R -6 is not sufficient.
  • For abrasion resistance of slurry
 ● ● 42 ± 7
OHJI 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
OHJI 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
OHJI 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)
 ● ● 70 ± 7
OHJI R-8
(R-18)
  • Soft rubber blended with hard rubber for vulcanization.
  • Applied to equipment that is subject to abrasion and strong impacts during operation.
  • The thickness of the anti-corrosion rubber lining to protect against operational impacts is designed and applied according to the specific requirements of each equipment type or product.
 ● ● 42 ± 7
OHJI R-8i
  • Compound of low Ca and Mg
  • Same as R-6 and R-8
 ● ● 42 ± 7

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

Ha Thanh is the only company in Vietnam that supplies genuine OHJI Natural Soft Rubber (R-4, R-5, R-6, R-16, R-7, R-17, R-8, R-18, R-8i) manufactured by OHJI Japan in Vietnam.
