Phenolic resins are available only in dark colour shades. They are not suitable for use with food. Typical appli- cations include thermally insu- lating operating elements. The material group Polyamide 6 (partially crystalline) offers univer- sal materials for mechanical function components in mechanical engineering. Polyamides are: - cold-temperature resistant - impact stress resilient and impact resistant - abrasion resistant Reinforced Polyamides, such as PA 6 GF30 or PA-HP, combine high stiffness and rigidity with extreme impact strength, properties which make them highly robust under mechanical stress. Polyamide PA-T (amorphous) is translucent with a slightly yellow transparency. Typically used for oil level sight glass. * + resistant, o conditionally resistant, – non-resistant Material Characteristics of Plastics Materials and Elastomers continued
