Phenolic tubing is produced from a dielectric Kraft paper that has been pre-impregnated with a special Phenolic resin and cured to the Class “B” stage. After forming, the tubes are baked to complete the resin cure. In this process, the Phenolic and the special adhesive coalesce to form a complete homogenous product. Phenolic tubing has excellent mechanical strength as well as good electrical properties. Strength for strength, Phenolic tubing provides a much thinner wall than Kraft alone. Phenolic tubing will also hold its shape better than Kraft; particularly under humid conditions.

plastic forming capabilities are highly customizable too. We can accommodate whatever type of closure is needed, partial or complete, without lengthy or pricey tooling preparation. We have the capability to produce proof seals with our advanced technology. Passing each part through a state-of-the-art Hi-Pot system ensures each product is manufactured to the highest quality standards. Special extrusion capabilities Our special extrusion capabilities include providing: Leak proof seals Clear tubing or colors, depending on the material Some tubing in continuous lengths of up to 5, 000 feet Some tubing available with formed ends (for containers or vials), depending on the material

Vulcanized fiber has been called the world’s oldest plastic. Using compatible adhesives for bonding, vulcanized fiber products are durable and offer excellent tear resistance, bonding surface, electrical insulation, impact strength and burst qualities. The electrical arc-quenching characteristics, used alone or in combination with other substrates, offers a low cost alternative to materials now being used as fuse bodies.

We also offer a unique tube adaptation process — called “bow” — for square and rectangular tubes. Bow tubes have convex sides, meaning the sidewalls are curved slightly away from the center of the tube. Four different degrees of bow are available from us: Paraformed – for flat sidewalls and flat inside corners (exclusive to us) Very slight – approximately .020″ of bow per inch of sidewall, per side; provides some degree of added strength Slight – approximately .030″ of bow per inch of sidewall, per side; adds strength Regular – approximately .040″ of bow per inch of sidewall, per side; provides maximum strength and resistance to collapse Bow tubes are best used when the tube must be wrapped tightly with magnetic wire during a transformer manufacturer’s winding process. Generally, bow is applied to Kraft paper and Kraft paper combinations only. We can, however, force bow in square and rectangular tubes made from other materials.
