Fiberglass Coated Silicone Sponge Sheet combines the core performance of foam silicone with the structural advantages of fiberglass. Designed for mid-to-high-end applications like industrial sealing, it features five key competitive advantages that precisely meet industrial clients' demands for "high reliability, strong durability, and easy processing".
PRODUCT DESCRIPTION
1. Extreme Temperature Resistance, Breaking Through the Limits of Operating Conditions
Wide temperature range stability:
The substrate is made of high-quality foamed silicone rubber, reinforced with a glass fiber coating, capable of withstanding long-term use at temperatures ranging from-60°C to 250°C. It can endure short-term exposure to high-temperature impacts up to 400°C and maintains excellent elasticity even in low-temperature environments, without brittleness or hardening.
Enhanced thermal stability:
The fiberglass coating creates an efficient thermal barrier that significantly reduces heat transfer rates. Compared to standard foam silicone boards, this design improves dimensional stability by 30% under high-temperature conditions, effectively preventing seal failures caused by thermal expansion and contraction.
II. Exceptional structural strength with dual compliance to tear and tensile resistance standards
Tearing resistance doubled:
The glass fiber fabric and foam silicone substrate are seamlessly bonded through high-temperature vulcanization, forming a composite structure of 'flexible substrate + rigid skeleton' with a tearing strength of ≥15 kN/m, significantly exceeding that of conventional foam silicone boards (≤8 kN/m).
Low elongation deformation rate: 50% increase in longitudinal/longitudinal tensile strength, with permanent deformation ≤3% under long-term stress (e.g., flange sealing, equipment clamping), effectively addressing the industry pain points of common foam silicone sheets prone to elongation and collapse.
Puncture-resistant and wear-resistant:
The surface glass fiber coating has higher hardness than the silicone substrate, capable of withstanding puncture and abrasion from sharp metals, sand, and other foreign objects, extending the product's service life by 3-5 times.
3. Dual Excellence in Sealing and Insulation, Meeting Industrial Needs in Multiple Scenarios
High airtight waterproof seal:
The closed-cell foam structure features uniform porosity, combined with seamless coating coverage, providing waterproof and dustproof performance. It also offers excellent barrier properties against gases and liquids (e.g., water, weak acids, and weak alkalis), making it ideal for sealing pipelines and enclosures.
Excellence in electrical insulation:
Glass fiber, an inherently insulating material, achieves a volume resistivity of ≥10¹⁴ Ω·cm when incorporated into composites. This makes it ideal for insulating and sealing new energy battery packs and high-voltage electrical equipment, effectively eliminating leakage risks.
IV. Chemically Corrosion-Resistant and Compatible with Complex Media Environments
The product demonstrates exceptional resistance to chemical erosion, a common issue in industrial environments.
Anti-aging:
Resistant to UV, ozone, and humidity, with no significant performance degradation after over 5 years of outdoor or harsh environment use.
Resistant to weak acids and weak alkalis:
Capable of withstanding low-concentration acidic or alkaline media such as dilute sulfuric acid and sodium hydroxide, suitable for sealing in chemical equipment.
5. Easy to process and install, reducing customer application costs
Customized processing is hassle-free: We can perform precise cutting, punching, and die-cutting to create any size or shape (e.g., gaskets, seals, or strips) based on customer drawings, with smooth cuts free from slag and seamless coating adhesion.
High installation adaptability: The product features excellent flexibility to conform to irregular surfaces, with a smooth coating surface that resists adhesion and dirt. No additional release agent is required during installation, significantly improving construction efficiency.
Fully mass-producible specifications: standard thickness 1-45mm, width 1000-1200mm, supports coil and sheet supply, with stable delivery times (7-15 days) for bulk orders, meeting customers' large-scale production needs.
