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…

  空気圧チューブを購入する際には、通常、いくつかの要素が考慮されます。チューブの寸法、最大使用圧力、柔軟性、価格は、購入希望者にとって重要な考慮事項です。しかし、空気圧チューブの製造に関連するその他の要素は、サプライヤーの製品の一貫性や購入者のサービス体験に大きな影響を与える可能性があります。ポリウレタンチューブの場合、チューブの製造に使用されるTPU樹脂のメルトフローインデックス（MFI）は、チューブの製造に使用される材料の最も重要な指標の1つです。TPU樹脂のMFIは、…を決定します。

  空気圧システム構築業者や空気圧チューブの産業用購入者にとって、チューブの品質は単に空気を移動させる以上の意味を持ちます。規格外のチューブは、漏れ、不十分な曲げ、ひび割れ、早期故障につながる可能性があります。ポリウレタン空気圧チューブを選ぶ際、多くの顧客は直径、色、価格を考慮します。しかし、チューブの品質を決定する最も重要な要素は、製造プロセスです。TPU押出成形プロセス、材料の品質、冷却、最終検査時の品質管理は、自動化機器や産業用途で使用される空気圧チューブの品質を左右する決定的な要素です。ポリウレタンチューブにおいて、押出成形プロセスが重要なのはなぜでしょうか…
