I. Core Pain Points in Industrial Machinery Applications
Under high-temperature conditions (e.g., in equipment chambers, pipeline insulation, or mechanical seal areas), conventional foam boards tend to soften, crack brittlely, or even powder and detach, contaminating internal equipment components and increasing maintenance costs.
After prolonged compression loading (e.g., during mechanical cushioning or seal pad operation), the resilience decreases and permanent compression deformation becomes excessive, resulting in poor sealing performance and cushion failure, thereby compromising equipment operational stability.
In harsh industrial environments (high temperatures + mechanical vibrations), foam boards have a short service life. Frequent replacements are not only time-consuming and labor-intensive but may also cause production line downtime and losses.
II. Core Selling Point
1. Excellent high-temperature resistance; completely prevents powdering after exposure to high temperatures.
It can withstand long-term exposure to industrial high-temperature environments ranging from-40°C to 200°C, making it suitable for high-temperature applications such as equipment chambers, high-temperature pipelines, and areas surrounding engines.
After 1000 hours of high-temperature aging tests, the material exhibited no softening, brittleness, or pulverization, retaining its original physical morphology and performance, thereby preventing equipment contamination or failures caused by material failure.
Special-grade foamed silicone can withstand temperatures up to 315°C for short-term use.
2. High rebound performance with low permanent compression deformation
The rebound rate is ≥150%, allowing rapid restoration to its original state after mechanical compression or vibration, ensuring sustained effectiveness of sealing, cushioning, and shock absorption functions.
The permanent compression deformation is ≤5% (tested according to GB/T 10654 standard). Even after prolonged stress exposure, it maintains its original dimensional accuracy without exhibiting "collapsing" or "deformation," ensuring stable sealing clearance and eliminating risks of air, oil, or gas leakage.
With high toughness and tear resistance, it withstands complex operating conditions such as frequent opening/closing, vibration, and impact in industrial machinery equipment, thereby extending its service life.
III. Model Selection Recommendations
Select the model based on temperature scenarios:
Conventional high-temperature environment (≤200°C): Opt for standard heat-resistant foam board for better cost-effectiveness.
Extreme high temperatures (200°C–250°C): Select high-specification heat-resistant models and use them with specialized adhesives to enhance thermal stability.
Select type based on the load scenario:
Light-load sealing/buffering (e.g., equipment door sealing, mild vibration buffering): Select the standard density variant (350–550 kg/m³).
Long-term heavy-load compression (e.g., high-pressure sealing, mechanical support and cushioning): Opt for the high-density variant (550–800 kg/m³), which offers stronger rebound and minimal deformation.
Select the model based on size requirements:
Standard dimensions (Thickness 0.8–50 mm, width ≤1200 mm) are available for immediate stock and same-day shipping.
Non-standard dimensions and special shapes (such as custom sealing gaskets or tailored cuts) can be tailored to specifications upon request; production can be customized upon providing the drawings.
