Junhua PEEK5600G PEEK particles
PEEK5600G is unfilled peek. This record separates grade composition from source-specific mechanical, impact and thermal reference values.
Grade distinction
PEEK5600G is identified by its composition rather than by a generic PEEK description. The unfilled peek formulation is kept separate from the other grades in the comparison table.
Document versions
The manufacturer’s English and Chinese tables report different mechanical reference values. The existing mechanical values and new impact and thermal values here retain the English table; composition is separately sourced to the Chinese grade table. Request the current grade datasheet and test conditions before making a design comparison. Typical data are not guaranteed finished-part properties.
