Rubber Application

Natural Soft and Hard Rubber

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.

SH composite rubber, combining soft and hard rubber, stands out with its high elasticity and good load-bearing capacity. This type of rubber is highly suitable for industrial applications due to its resistance to acids, alkalis, and abrasion. With advanced technology and manufacturing processes, this composite rubber delivers outstanding performance for a wide range of equipment and applications.

Characteristics

  • ( 01 )

    High Elasticity

    The rubber compound has excellent stretch and shape recovery capabilities, making it suitable for applications requiring flexibility.
  • ( 02 )

    Good Load-Bearing Capacity

    This material can withstand tensile and compressive forces without deforming, ensuring durability during use.
  • ( 03 )

    Abrasion Resistance

    The rubber compound is resistant to abrasion, giving products a long service life even when subjected to continuous friction.
  • ( 04 )

    Vibration Damping Capability

    The rubber compound can absorb and minimize vibrations, reducing noise and protecting equipment.

Although soft rubber type (R, C, B and S type) is not be damaged by shock or vibration, there is a problem in this point for hard rubber type (E type). When hard rubber is used for corrosion resistance and shock and vibration resistance need to be taken advantage, triple layer application or soft~hard~soft (SH type) is used.

SH (Sunhard) specifies the sign of each structure (hard –soft and soft-hard-soft) from metal surface, and the contents of thickness and material differs depending on the required service condition.

In this case, therefore, it is separately specified. Designed value of standard hardness differs from by each rubber structure.
