    MR and VB Films for Composite Molding

    CHEMFILM MR and VB Films for Composite Molding
    CHEMFILM® MR films (mold release films) combine the chemical inertness and universal non-stick properties of PTFE polymers with maximum conformability and heat resistance. Compare the data for CHEMFILM MR versus other materials typically used in composite fabrication in order to understand its superior performance, particularly for complex shapes and high temperature resins
