EPDM Glazing Bead (Glass Panel Insert)

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber with superior resistance to a wide range of environmental factors. One of the key attributes of EPDM Glazing Beads is their ability to withstand extreme temperature fluctuations, from high heat to freezing conditions, without degrading or losing mechanical properties. EPDM retains its flexibility and elasticity over time, even when exposed to prolonged UV radiation, ozone, or moisture. This makes it an ideal material for external applications where materials are regularly exposed to outdoor conditions, such as on building facades, windows, and glazing systems for vehicles.

Materials

EPDM (Ethylene Propylene Diene Monomer), offering excellent flexibility, durability, and weather resistance.

Surface Finishes

Smooth, non-porous surface with options for textured finishes to enhance sealing and aesthetic appeal.

Compliance Standards

Meets ASTM D2000, ISO 9001, REACH, RoHS, ensuring conformity to global material and safety standards.

Cross-Section Area (A)

Cross-sectional area of 5 to 20 mm², tailored to specific glazing bead profiles for effective sealing.

Mass per Meter (m)

Typically ranges between 20 to 40 grams per meter, depending on bead profile and material density.

Product Description

The molecular structure of EPDM, which includes ethylene, propylene, and a diene component, gives it exceptional resilience against environmental degradation, unlike many conventional sealing materials that may crack, become brittle, or lose effectiveness under similar conditions. This resilience translates into a longer service life for both the bead and the entire glazing system, reducing the frequency of replacements and ensuring long-term functionality in the most demanding climates.

Moment of Inertia (Ix / Iy)

X-axis: 0.01–0.1 mm⁴ (bead design, bending resistance); Y-axis: 0.01–0.1 mm⁴ (perpendicular stiffness).

Section Modulus (Zx / Zy)

Typically from 0.5 to 5 mm³, representing the distribution of material to resist bending forces.

Radius of Gyration (ix / iy)

Varies from 0.1 to 1.5 mm, indicating the distribution of material relative to its axis of rotation.

Max. Axial Load (Euler Buckling)

Typically 5 to 50 N, indicating the load at which the bead may buckle or deform axially.

Max. Load at Slot (Shear Test)

Load resistance of 50 to 300 N, indicating bead’s ability to withstand shear forces at the slot.

Torsional Constant (J)

Varies from 0.01 to 0.1 mm⁴, indicating the bead’s resistance to twisting and rotational deformation.

Max Torque (Torsional Load Limit)

Rated between 1 to 10 N·m, reflecting the maximum torque the bead can withstand without failure.

Elastic Deflection (100 N Load)

Typically between 0.1 to 1 mm, showing how much the bead deflects under a 100 N load.

Dynamic Load Rating

Rated for continuous dynamic loads up to 500 N/m, ensuring durability under moving or fluctuating forces.

Compatibility Tolerance

Tolerance of ±0.5 mm, allowing for proper fitment with glass panels and frame structures.

Machining Precision Grade

Achieves machining tolerances of ±0.1 mm, ensuring high-precision manufacturing for effective sealing.

Fatigue Life (Slot Edge)

Typically over 10⁶ cycles, showing the bead’s ability to withstand repeated dynamic loading.

Thermal Expansion (ΔL @ ΔT=50°C)

Ranges from 0.0002 to 0.0004 mm/°C, indicating low thermal expansion across temperature variations.

Slot Pull-Out Resistance

Ranges from 100 to 500 N, reflecting the bead’s ability to resist pull-out from its slot under force.

Max Load Bearing at Corner Joint

Ranges from 200 to 1000 N, indicating the bead’s strength to resist forces at corner joints.

Technical Advantages

In high-performance glazing systems, ensuring the integrity and stability of glass panels under mechanical stresses is crucial. Glass panels are subject to external forces such as wind loads, thermal expansion, and mechanical impacts. EPDM Glazing Beads are engineered to accommodate these stresses by providing a precise, resilient fit between the glass and its frame. The bead’s design ensures it can maintain the pressure and load distribution required to keep the glass in place, preventing displacement during external disturbances.

The compression set resistance of EPDM allows it to maintain its sealing and retention function under constant pressure, ensuring that glass panels are securely fixed within the frame. The elasticity of EPDM allows it to conform to slight irregularities in the frame or glass, ensuring a uniform seal and reducing the risk of glass movement or failure.

Doors and Windows

Seals glass in door and window assemblies, preventing moisture infiltration while providing sound and vibration damping in high-traffic areas.

Airtight and Watertight Sealing Properties

The sealing capabilities of EPDM Glazing Beads are critical for applications that require a tight seal to prevent water, air, and dust infiltration. In buildings and vehicles, preventing leaks is essential not only for comfort but also for energy efficiency. EPDM’s closed-cell structure provides a robust barrier against water penetration, while its high compressibility ensures that it creates a tight seal along the entire perimeter of the glass panel.

The bead’s low permeability to gases and liquids is a direct result of EPDM’s unique molecular structure, which resists the passage of water molecules and prevents the formation of leaks or air gaps. In applications such as window frames, curtain walls, and automotive glazing, the EPDM Glazing Bead helps maintain a dry, insulated, and controlled environment, even under extreme weather conditions.
