2. List of insulation materials - Wikipedia

   en.wikipedia.org/wiki/List_of_insulation_materials

   This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.

3. Paper composite panels - Wikipedia

   en.wikipedia.org/wiki/Paper_composite_panels

   Since the last quarter of the 20th century, phenolic resin and cellulose based compound materials have been used as an alternative to ebony and rosewood to make stringed instrument fingerboards. [3] From 2012 to 2018 guitarmaker Gibson used Richlite , a paper composite material, for the fingerboard on several top-of-the-line production guitars.

4. Phenol formaldehyde resin - Wikipedia

   Phenolic micro-balloons are used for density control. The binding agent in normal (organic) brake pads, brake shoes, and clutch discs are phenolic resin. Synthetic resin bonded paper, made from phenolic resin and paper, is used to make countertops. Another use of phenolic resins is the making of duroplast, famously used in Trabant automobiles.

   The back of two circuit boards. The brown one is an FR-2 made of paper phenol. Phenolic paper is a material often used to make printed circuit board substrates (the flat board to which the components and traces are attached). It is a very tough board made of wood fibre and phenolic polymers. It is most commonly brown in colour, and is a fibre ...
