The matrix material used is a phenolic resin molding compound (type: Bakelite X22; manufacturer: Hexion GmbH, Iserlohn, Germany), which is suitable for additional fillers due to its higher resin content. The trials are carried out on an Allrounder 370A – 600 injection molding machine (manufacturer: Arburg GmbH + Co KG, Lossburg, Germany) equipped with a ...

The entire subsequent development of the electrical industry was only made possible by phenolic resins (Bakelite), which served as an insulating and construction material. The actual use of plastics as substitutes during the raw material blockade in The First World War dealt another blow to their image, especially in Germany. Inferior-quality viscose staple fibers were not particul...

...t the start of the 20th century, phenolic resins marked the dawning of the age of fully synthetic materials. In 1907, Leo H. Baekeland discovered the condensation polymerisation of phenol and formaldehyde to form resins (Bakelite). These resins had excellent electrical properties, which made them a much sought-after housing material for the burgeoning electrical industry. The material could be compression moulded, allowed high-volume article production, and its starting materials, phenol and for...

Both parameters are dependent on the pressure p. Injection Mould At Bakelite AG in Iserlohn, an existing injection mould was converted to produce two standard dumbbell test bars (Fig.2). Standard longitudinal wave sensors (Fig.1) with 4MHz centre frequency were used. The sensors were fitted flush into the mould wall. The measure...

In technical time frames polyurethanes, which are “just” 73 years old, are no longer the subject of across the board development, but particularly in application technology the R&D work continues with bright prospects. There are almost certainly a great number of holes, surfaces and gaps that could sensibly be filled with PU. On top of that are further ingenious treasure trove...
