Section Modulus (Zx / Zy)

Ranges from 0.001 to 0.010 mm³, indicating the material’s capacity to resist bending.

Radius of Gyration (ix / iy)

Ranges from 0.15 to 1.50 mm, reflecting material distribution’s resistance to buckling and deformation.

Max. Axial Load (Euler Buckling)

Can handle 50-200 N depending on profile and material, preventing premature deformation or failure.

Max. Load at Slot (Shear Test)

Withstands 200-500 N, ensuring the weatherstrip maintains structural integrity under shear forces.

Torsional Constant (J)

Typically 0.01 to 0.15 mm⁴, determining the material’s resistance to twisting and rotational stress.

Max Torque (Torsional Load Limit)

Can tolerate 5-20 N·m depending on profile and material, ensuring torsional stability under loads.

Elastic Deflection (100 N Load)

Maintains ≤ 1 mm deflection under 100 N load, ensuring structural stability and effective sealing.

Dynamic Load Rating

Ranges from 150-1000 N, indicating performance under varying dynamic loading conditions and cycles.

Compatibility Tolerance

Tolerances of ±0.2 mm for standard profiles, up to ±0.5 mm for custom design shapes.

Machining Precision Grade

Standard precision is ±0.1 mm, with custom tolerances available for specialized applications.

Fatigue Life (Slot Edge)

Can endure between 10⁶ and 10⁸ cycles, depending on load, profile, and environmental factors.

Thermal Expansion (ΔL @ ΔT=50°C)

Exhibits 0.05 to 0.15 mm/m expansion, ensuring stability in fluctuating temperature environments.

Slot Pull-Out Resistance

Typically ranges from 50-200 N depending on profile, material, and application conditions.

Max Load Bearing at Corner Joint

Supports up to 200-1000 N, ensuring stability at joint connections in harsh conditions.

Technical Advantages

TPE and EPDM weatherstrips offer superior thermal insulation, reducing heat transfer and minimizing air leakage. Their closed-cell structure helps maintain consistent interior temperatures, reducing energy costs by preventing heat loss or gain, which is critical for energy-efficient building and automotive applications. 

Both materials are highly effective in noise reduction, thanks to their density and elasticity. Their ability to absorb sound waves and prevent vibration transmission enhances acoustic performance, making environments quieter by blocking external noise—ideal for both automotive and construction applications.

Construction

Applied in building windows and doors to prevent air infiltration, water leakage, and enhance thermal insulation for energy efficiency.

HVAC Systems

Used for sealing ventilation units, preventing air leaks and improving energy efficiency while maintaining performance under high-pressure conditions. 

Aerospace

Provides critical sealing for aircraft windows, ensuring resistance to extreme temperatures, vibration, and chemical exposure in harsh environments. 

Rail Transport:

Seals railway carriage windows to prevent water ingress, resist UV degradation, and provide sound insulation against external noise. 

Marine

Applied in sealing boat and ship windows, providing resistance to saltwater, UV exposure, and extreme weather conditions. 

Customization for Specific Performance Requirements

These materials can be tailored to meet specific hardness, tensile strength, and dimensional stability needs. Customizing properties such as compression set resistance and flexibility ensures optimal sealing performance in unique applications, from high-pressure systems to dynamic sealing environments. 

TPE and EPDM offer excellent abrasion resistance, ensuring that the weatherstrips maintain their sealing integrity over time. TPE is especially durable in high-wear applications, where frequent movement or compression is involved, ensuring consistent performance even under repeated stress. 

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure the consistent quality of TPE/EPDM window weatherstrips across different production batches?

Frigate employs rigorous quality control measures, including material testing, dimensional checks, and environmental testing. Each batch of TPE/EPDM is subjected to heat aging, chemical resistance, and compression tests to ensure long-term durability. Our production facilities maintain precise temperature and pressure controls to ensure uniform material properties. This systematic approach guarantees consistent performance for every weatherstrip produced. 

What testing methods does Frigate use to verify the chemical resistance of TPE/EPDM weatherstrips for automotive applications?

Frigate conducts extensive testing for chemical resistance, including immersion tests in oils, fuels, and solvents commonly found in automotive environments. The weatherstrips are exposed to these substances at various temperatures to simulate real-world conditions. We also perform elongation and tensile strength tests after chemical exposure to verify the material’s integrity. This ensures the weatherstrips retain their sealing function despite exposure to harsh automotive chemicals. 

How does Frigate address the challenges of UV degradation in outdoor weatherstrip applications?

Frigate sources high-quality UV-resistant EPDM and TPE compounds that are specifically designed to withstand prolonged exposure to sunlight. We conduct accelerated UV exposure tests to simulate years of outdoor usage in a shortened time frame. Additionally, we monitor weatherstrip flexibility, strength, and surface integrity post-UV exposure. This ensures that Frigate’s weatherstrips maintain their sealing performance and aesthetic quality even after long-term exposure to UV rays. 

 

How does Frigate ensure TPE/EPDM weatherstrips meet the strict environmental standards for building and construction applications?

Frigate adheres to industry-specific environmental standards by sourcing materials with low volatile organic compounds (VOCs) and ensuring the weatherstrips are free from harmful chemicals. We perform comprehensive emission testing and confirm that all materials meet global environmental regulations. Additionally, the weatherstrips are subjected to thermal cycling tests to ensure they perform effectively across a wide range of temperatures. This compliance guarantees that our products contribute to energy-efficient and environmentally sustainable building practices. 

How does Frigate optimize TPE/EPDM weatherstrips for sound insulation in transportation applications?

Frigate designs TPE/EPDM weatherstrips with an optimal balance of density and elasticity, which enhances their ability to absorb sound vibrations. We run detailed acoustic testing in controlled environments to assess noise reduction performance. The materials are engineered to minimize sound transmission by preventing gaps and leaks around windows and doors. This technical focus ensures that the weatherstrips contribute to a quieter, more comfortable interior in automotive, rail, and marine applications.
