Rubber Dam Bag

Our industrial-grade rubber dam bags are engineered with a specialized fabric-reinforced multi-layer structure, utilizing high-strength reinforcing and protective canvas to bear heavy tensile stress. The outer rubber layer provides exceptional resistance to abrasion, ozone, and UV heat, while the inner layer ensures absolute watertightness and airtightness. Designed to accommodate heights from 1.0m to 6.0m with rigorous safety factors and internal pressure ratios. Contact our manufacturing facility directly for custom OEM specifications, detailed technical datasheets, and bulk order pricing.

  • Detailed Description

The fabric-reinforced rubber material used for the rubber dam bag consists of reinforcing canvas, which bears the tensile stress of the dam bag, and protective canvas, integrated with rubber layers that ensure airtightness.

The rubber layers are typically distributed across the outer, middle, and inner sections of the dam bag, with each layer performing its specific function.

Outer Rubber Layer:

Given the prevalence of floating debris in rivers, our company uses a specialized rubber formulation with exceptional resistance to abrasion, sunlight, heat, and ozone.

Middle Rubber Layer:

This layer directly protects the canvas; it serves as a bonding agent for the two or more layers of canvas, ensuring superior adhesion between the rubber and the fabric.

Inner Rubber Layer:

In addition to its function of protecting the canvas, this layer provides a high degree of watertightness and airtightness.
