    Overview

    BDT Series: Advanced Curative-Incorporated Terpolymer FKM for Aggressive Fluid Resistance

    The BDT Series (Terpolymer FKM) is a high-performance line of curative-incorporated fluoroelastomers designed to surpass standard copolymers in the most demanding environments. By utilizing a terpolymer backbone (VDF/TFE/HFP), this series offers superior resistance to aggressive fuels, oils, and chemical solvents, making it the ultimate choice for automotive, aerospace, and industrial fluid systems. Featuring an integrated curing system, the BDT series ensures exceptional batch-to-batch consistency and optimized scorch safety across a wide viscosity range. Our ChipChill coolant helps IDC centers achieve a PUE value close to 1.0, while our FSA is critical for new energy lithium battery PVDF adhesives and solar cell backsheets. Our elastomer products serve the automotive, petroleum, chemical processing, and wearable electronics industries due to their excellent resistance to high temperatures and corrosion.

    Product Advantages

    • 01

      Superior Fluid Barrier

      The terpolymer structure provides significantly enhanced resistance to fuels and chemicals compared to traditional FKM copolymers.

    • 02

      Precision Curative Integration

      Built-in curing agents eliminate mixing errors, providing a fast cure rate and consistent physical properties for every production run.

    • 03

      Arctic-Grade Flexibility (BDTL Series)

      The BDTL40P grade is specifically modified to maintain sealing integrity in extreme cold without sacrificing fluid resistance.

    • 04

      High-Fluorine (HP) Options

      Grades like BDT601HP offer high crosslinking and maximum chemical resistance for critical industrial gaskets.

    • 05

      Efficient Processing

      Specialized grades like the BDT246 Series allow for shortened post-cure times at lower temperatures, reducing energy costs and increasing output.

    • 06

      Exceptional Mechanical Bonding

      High-viscosity grades (e.g., BDT651P) provide the "hot tear" strength required for complex metal-to-rubber bonding in oil seals.

    Material & Manufacturing Process

    1. Chemical Structure: A specialized blend of Vinylidene Fluoride (VDF), Tetrafluoroethylene (TFE), and Hexafluoropropylene (HFP), precisely balanced to optimize fluorine content.
    2. Our equipment Supported by advanced equipment such as short-path molecular distillation and electronic-grade purification filtration, we ensure superior product quality.
    3. Compounding Versatility: Fully compatible with standard FKM fillers and additives; can be processed using Internal Mixers or Two-Roll Mills.
