Pneumatic tubing is often selected by outside diameter, pressure rating, color, and price.That may be the case for many standard airlines, but it ignores one critical characteristic that may be of great importance in the case of vacuum systems, high-voltage circuits, and low-flow instruments: air permeability. In other words, gas molecules are highly likely to flow through an untarnished polymer membrane, thus, reducing pressure on the designed side and degrading the system’s performance. The extent of permeation depends on the plastic material, wall thickness, temperature, pressure differential, and gas type. Therefore, permeability has to be considered along with the bending…

Polyurethane Pneumatic Tubing Rarely made from base resin only. A variety of stabilizers, processing aids, pigments, lubricants, and modifiers may be added to improve its resistance to heat, moisture, sunlight, chemicals, abrasion, flexing, or other factors. The challenge is that one additive may negate the effect of another, such as by making the material too hard or too flexible. A compound that adds flame resistance could also lower the tensile strength or cause problems like discoloration. Buyers considering multiple additives should ask how they complement each other and what testing was done on the final tubing. It is also important to…

  In choosing polyurethane pneumatic tubing for use in machinery, the consumer can get an engineering specification full of data regarding materials and numbers. Nonetheless, all this information is only important to the extent that it is relevant to the application. Working pressure, bend radius, temperature range, chemicals exposure, and fittings compatibility are some of the factors that determine how relevant the information will be. Pneumatic tubing datasheets serve the purpose of avoiding complications associated with choosing the wrong tubing. What information should engineers check first on a pneumatic tubing datasheet? A technical data sheet generally provides plenty of information, but…

  In pneumatic tubing manufacture, the preparation of material prior to extrusion is likely to have an impact on the uniformity and performance of the tubing itself. In cases where multi-material tubing is manufactured using multiple types of polymer material in the construction, the control of moisture levels prior to processing assumes importance for manufacturers. The selection of tubing manufacturers requires not only consideration of the final properties of the tubing but also the manner in which the materials used in the manufacture process are processed. Why does material drying matter in pneumatic tubing manufacturing? Before polymer materials enter the extrusion…

  Lors de l'achat de tubes pneumatiques, plusieurs facteurs sont généralement pris en compte. Les dimensions du tube, la pression de service maximale, la flexibilité et le prix sont autant d'éléments importants pour les acheteurs potentiels. Cependant, d'autres facteurs liés à la production des tubes pneumatiques peuvent avoir un impact significatif sur la constance des produits d'un fournisseur et sur l'expérience client. Pour les tubes en polyuréthane, l'un des indicateurs les plus importants des matériaux qui les composent est l'indice de fluidité à chaud (MFI) de la résine TPU utilisée dans leur fabrication. Le MFI d'une résine TPU détermine…

  Pour les fabricants de systèmes pneumatiques et les acheteurs industriels de tubes pneumatiques, la qualité de ces derniers ne se limite pas à la simple circulation de l'air. Des tubes de qualité inférieure peuvent entraîner des fuites, des courbures incorrectes, des fissures et une défaillance prématurée. Lors du choix de tubes pneumatiques en polyuréthane, de nombreux clients prennent en compte le diamètre, la couleur et le prix. Cependant, le processus de fabrication est le facteur déterminant de leur qualité. L'extrusion du TPU, la qualité du matériau, le refroidissement et le contrôle qualité lors de l'inspection finale sont des éléments essentiels pour les tubes pneumatiques utilisés dans les équipements d'automatisation et les applications industrielles. Pourquoi l'extrusion est-elle si importante pour les tubes en polyuréthane ?
