Superior chemical resistance FKM (Peroxide Cured) BDP Series fluoroelastomer
Overview
BDP Series: 70% High-Fluorine Peroxide Curable FKM for Steam & Amine Resistance
The BDP Series (High-Fluorine Peroxide Curable FKM) is a pinnacle of chemical barrier technology, engineered with an ultra-high fluorine content of 70% and a specialized peroxide cross-linking system. Unlike standard FKMs, the BDP series delivers extraordinary resistance to high-temperature steam, aggressive acids, and amine-containing chemicals, making it indispensable for petrochemical and chemical processing industries. With an optimized formula providing excellent mold flow and hot tear resistance, this series achieves a drastic reduction in post-cure time (only 4 hours), significantly boosting production throughput. Whether for precision O-rings with complicated geometries or specialized Pearl White decorative components, the BDP series ensures a flash-less, high-performance seal with unmatched weatherability and dimensional stability.
-
Peroxide Cure Superiority
Provides significantly better stability in Steam, Amines, and Aqueous Acids compared to traditional bisphenol-cured FKMs.
-
High-Speed Production
Optimized for efficiency with a Short Post-Cure Cycle (4hrs), reducing energy consumption and accelerating lead times.
-
Precision Engineering
Superior mold flow and release properties result in "Less Flash" production, perfect for intricate parts and complicated geometries.
-
Enhanced Bonding (BDP-H9751)
Specifically engineered for improved bonding to Silicone Rubber (VMQ), ideal for multi-material gaskets and hybrid components.
-
Aesthetic & Weatherability (BDP-B9701)
Features a unique Pearl White grade with outstanding resistance to UV and outdoor weathering for high-end decorative seals.
Material & Manufacturing Process
- Advanced Cross-linking: Utilizes a peroxide-based vulcanization mechanism to create a more robust molecular network that resists hydrolytic and chemical cleavage.
- High-Purity 70% Fluorine Base: Formulated using premium terpolymers to achieve the maximum chemical barrier required for Alcohol-Fuel and Petrochemical
- Homogeneous Compounding: Processed under strict temperature controls to ensure a perfectly uniform curative dispersion, preventing "weak spots" in finished molded parts.
Solutions & Application Scenarios
- Petrochemical & Oil/Gas: Critical gaskets and O-rings exposed to Amine-based corrosion inhibitors and sour gas environments.
- Plate Heat Exchangers (PHE): Specifically BDP-H9751 for gaskets requiring long-term resilience against high-pressure steam and thermal cycling.
- Automotive Fuel Systems: Seals for flex-fuel engines where 70% fluorine is required for zero-permeation of ethanol-blended fuels.
- Chemical Processing: Diaphragms and valve seats handling concentrated acids and various organic chemicals.
Technical Processing Guide
-
Molding Versatility: Optimized for Injection, Transfer, and Compression molding.
- Press Cure: Typically 2-5 min @ 165-170°C, adjustable based on part thickness and geometry.
- Pre-Processing: It is highly recommended to re-mix (re-mill) the compound before molding to ensure optimal plasticity and scorch safety.
