ePTFE membranes in battery vents: Quality assurance tests
Particularly to ensure safe, long-term use of lithium-ion batteries in motorized vehicles, functional venting systems are essential to compensate for temperature and pressure fluctuations. Battery housings sealed to protect against external influences are highly susceptible to pressure or temperature changes due to the lack of replaceability options. If these are not compensated for, damage to[…]

Classification of insulation materials and limiting temperatures
Insulation material classes are generally used to characterize and specify insulating materials regarding their thermal resistance. Thus the insulation material classes provide a clear, standardized classification of the respective materials according to their maximum operating temperature. Consequently, different classes with varying limit temperatures have been defined. In order to ensure long-term functionality in operation, these[…]

Corrugated pipes: Applications and product properties
Corrugated pipes consist of plastic-based insulating material pipes with diameters varying in a corrugated shape. Manufactured from a rigid material, the pipes are dimensionally stable, while the surface corrugation increases the product’s flexibility, particularly in moving applications. Furthermore, this facilitates the laying of the corrugated tube. Almost all common plastics qualify as material for the[…]

FP liner as PTFE alternative: production and application
PBT (polybutylene terephthalate) is a thermoplastic from the polyester group with properties comparable to semi-crystalline polyethylene terephthalate (PET). GREMCO manufactures the thermoplastic fluorinated polymer alloy FP (Fluorinated Engineering Polymer) based on the PBT base polymer, whereby the PBT is upgraded by the incorporation of fluorinated additives. Thanks to these fillers, the resulting FP liners are[…]
