Here a snipet to help achieve this:

from preview_generator.preview.builder.office__libreoffice import OfficePreviewBuilderLibreoffice
from preview_generator.preview.builder.pdf__pypdf2 import PdfPreviewBuilderPyPDF2
from preview_generator.preview.builder.plain_text import PlainTextPreviewBuilder

pdf_ready_mimetypes = []  # type: List[str]
pdf_ready_mimetypes = \
    OfficePreviewBuilderLibreoffice.get_supported_mimetypes() + \
    PdfPreviewBuilderPyPDF2.get_supported_mimetypes() + \
    PlainTextPreviewBuilder.get_supported_mimetypes()
enable_pdf_buttons = \
    file.file_mimetype in pdf_ready_mimetypes  # type: bool

Mimetypes we know for pdf are application/pdf, application/x-pdf
