The invention relates to a method of joining parts (1, 2) made of polymeric materials. The method consists in forming over the first and the second part (1, 2) a joining surface (10, 20) and then in submitting the joining surface of each part to a surface activation treatment. The ...
On the opposite end of the impact spectrum, heavier organic materials such as items made entirely of paper, rubber and wood dominated. Often, items of similar purposes were positioned on polar ends of the index, having been scored both in plastic form and in an alternative material; for ...
[0032] In the framework of the present invention it is thus evident that if a ceramic micromanufactured item should be produced, a material having in practice chemical/physical and Theological properties which are typical of polymeric materials (and is therefore easily worked with known systems, su...

FIELD: heating systems, drying.;SUBSTANCE: invention refers to devices for cooling and drying the items produced during extrusion of polymeric materials, and can be used in chemical, food, construction and other industries. Items cooling and drying device includes frame, housing inside which on ...
(HDPE), however other polymeric materials may be substituted depending on the application, including the provision of additives for reducing static electricity. HDPE works well due to its combination of stiffness, flexibility and memory (i.e., its tendency to return to its original shape after ...
Polycondensation of oligomeric or polymeric fatty acids and other multifunctional carboxylic acids like maleic acid or itaconic acid with multifunctional polyols is shown in EP-A0980882. After crosslinking these materials show good thermal and adhesive properties, however they are very soft and do not...
The capsular vehicles include vehicles often used for drug delivery, such as liposomes, and time release capsules; and also capsules made of glass, plastic and other such materials. For example, the bioluminescence generating reagents (or components) may be coated on the inside of a glass ...
Nor may the curing temperatures be too high, since otherwise the lead insulation, which is often made of PVC, may suffer damage. The invention provides a method for jacketing an elongated item such as more particularly leads or cable sets, where a stretched shrink-wrap film is guided in a ...
